Blog about outdoor products I personally believe fit under the category of "HARDCORE" By this I mean not only well-made but totally functional for serious pursuits, either on land or beneath the seas. As a diver, caver and scientist, I want to be able to rely upon my gear.

Nieto Knives RANGER XXL Lock Back Folder in N695 and G10 construction and XLNT folder.
Types of folding knives
Slip joint (non locking) folding knives are a very old design but appear to be coming back into vogue (in certain European countries) due to increased media hype surrounding the so called "knife crime"- which BTW is mainly orchestrated by hands attached to afflicted minds whereby those persons are certainly not using 100 buck plus hunting knives for their primeval doings but mainly home made devices and hardware tools of the carpenter! The authorities are of the opinion that a small slip joint knife is somehow less dangerous in such hands than a similar or even bigger sized locking knife. Funny that, as I distinctly remember being attacked by such a person during high school years who was a mere half metre or so from me, playing with a small slip joint knife and then lunging at me with intent to do bodily harm. Of course I remember it, especially how the Pang Gai Noon grip upon his thrusting arm resulted in all cessation of any idea of sticking it to me in the guts. Slip joints cut and stab just as well as any knife, period.
I digress and one can write volumes on the existence of knife crime and who are the key perpetrators of such violence.
The slip joint, while a favourite amongst many, is not the best choice for the outdoor enthusiast except for the traveller where a Swiss Army type knife would be a lot handier than any of the knives discussed below.
Lock back knives have been used by just about everyone who says: "Ive been using knives for ages"! In fact I would argue that anyone over the age of 45-50 in 2020 will fit into this category. So that means all of you "young'ns" had better listen up.
Stockmen, farmers, hunters, campers, soldiers, hikers etc. etc. have been using lock back knives for donkey's years!
Along comes the Liner lock, a weaker locking mechanism (there are exceptions of course, however, these are modified locking systems and still by definition are a "Liner lock") compared to a lock back. Whoa! Who says so? I do! (if we have to go down this ridiculous "strong Vs weal route"). The stop pin for example of the liner lock undergoes a bending and shear force when large forces are placed upon the blade because the blade is acting as lever upon the fulcrum (being the pivot) in attempting to move the immovable, ie the stop pin.
In order not to shear the stop pin, it must be thick enough and constructed with quality engineering in mind. The contact surface of the liner against the back of what could be considered the "knife tang" is small (Pressure = Force divided by Area) compared with that of the actual tang width. That is not ideal and for the liner to correctly "lock up" both liner surface and tang surface must be perfectly aligned and machined/ground in such a way s to form two "wedges" if you like. However, pressure against this wedge will only cause possible movement away from the lock position, hence the advent of the LAWKS system and variations of this (also see below).
Also when a force is applied to the liner lock (there are some exceptions (eg the treated tangs and end of the liner in some FKMD knives, which greatly improve the friction between the two mating surfaces) and the liner locks within the HF1 and HF2 series folders of Extrema Ratio, where a "safety locking pin" can be inserted into both frame and knife tang to bolster the blade and turn it into a "semi" (my words) fixed blade knife. Here the main forces are only acting upon the main pivot and the "safety locking pin". Other manufacturers such as J and V (Spanish company) utilise a safety locking pin on some liner lock folding models and so does the Italian company Wanderer (although the locking pin is used on a Roller lock mechanism and not a liner lock). I'm sure I have left many out here of this brief discussion. But I digress.
What about the LOCK BACK FOLDER????
Not so with the lock back folder where the tang of the blade usually matches in width the large slab of steel which undergoes compressive forces, (not bending forces as in a lock back design). Note, equivalent sized lock back knives are usually heavier than liner lock counterparts (but we are talking nothing really in weigh differences, differences which only matter to the weight junkies out there).
When it comes to reliability and longevity the Lock back design is king at present (ok liner locks and frame locks just haven't been around for that long yet, so maybe the jury is still out?)
When properly designed, the lock back knife is a very strong and safe design. It is virtually impossible for the blade to become accidentally released when subject to strong forces, unlike many modern designed liner and frame lock knives where the emphasis appears to be on the ease of opening. This latter aspect carries a disadvantage requiring the knife when folded to be carried either confined within a trouser pocket using the clip provided or within a small pouch (sometimes supplied), especially flipper folders of any description. A ball indent on both frame and the liner of liner lock and frame lock knives, can if properly engineered will help to restrain the blade from accidental release when subjected to mild forces (far under the forces required to release a traditional back locking folder, however these knives should IMHO NEVER be carried loose in a bag or rucksack for safety.
Reduction of pivot friction can also be achieved by substituting either plastic or bronze phosphor washers with thrust bearings at the expense of overall manufacturing costs and also increasing the frequency of maintenance over time due to contamination and or breakdown of the thrust/ball/roller bearing cassettes.
The lock back design folder has a much greater surface area of blade tang in contact with the actual structural part of the knife frame, whereas in a liner lock, frame lock, roller lock; all of these designs the only point of contact with the knife frame is via the friction reducing washers or bearings, which in most cases never cover the entire frame area.
A con with the lock back design is that they generally require more attention to lubrication and cleaning around the pivot because there are no washers or bearings and for the knife blade to exit and close smoothly the interface (sub millimetre) MUST be well lubricated and kept clean of foreign debris, especially extremely fine silt/dust, animal guts and oils, all of which if left to dry can impede the operation of the blade.
Because there is basically no "space" between blade and structural liners there is of course little chance for debris to become lodged within however, this does not, as mentioned, preclude liquids entering and congealing within the mechanism (although one would have to be very sloppy in knife maintenance.
The force from the heavy spring in the lock back knife helps to retain the blade in a closed form even if the blade was to become partially open, most good* designs will in fact return the blade to its closed position. Many "modern designs" of locking knives, once the blade exits the frame, it can move effortlessly and this is IMHO a big mistake with knife design for knives intended for outdoor usage.
* It must be a good design and not incorporate some woosy spring system!
What about Frame Locking knives?
Frame lock, another weaker design than the lock back for the same reasons stated above. It's funny how people are fixated upon "weaknesses" in fixed bladed knives but have totally been brainwashed to ignore any weaknesses in the frame lock. Of course though for general usage the frame lock is more than good enough to be safe. To mention CS's triad lock, a reinvention of the "lock back wheel" is neither a frame lock nor a liner lock nor a roller lock and hence it really achieves (supposedly) great strength in the locking mechanism. I say supposedly as I do not own one and CS would never dream in a thousand years of sending me one for review (that's a long story). The achieved strength is of little consequence as the probability of exerting the forces to close a knife as they demonstrate are highly unlikely but that's CS. Now don't get me wrong CS makes some great products, if not kings of showmanship!
Auto assisted liner locks in another article
Roller type lock Already discussed in previous articles here on this blog.
Now to use as an example of a classic design in locking knives, I present the following:
Nieto Knives RANGER XXL R011 G10 Lock back Survival Folder fully made in Spain featuring Böhler's N695 (their version of 440C) stainless steel with a HRC of XX? LOL, they don't say what the HRC is, which is quite strange. In fact the HRC is not mentioned on any of their social media sites, nor on any written material provided with the knife or their official web site. My guess is that they are covering themselves to be able to modify this ant any time in the future. When the Nieto Ranger XXL first came out in 2019, only red liners were offered, not the "toxic green" ones like in the one I just bought.
The Nieto engraving is now featuring an improved font that gives an air of modern design and the old Nieto font was exactly that, it just looked "OLD"!
On first examination of this folder I found ALL components to be perfectly aligned and functioning as expected. The knife itself came very well oiled in a plastic bag in their typical silver colored cardboard boxes. The only literature included was a publicity brochure, which BTW did feature also a picture of said knife.
I have many Nieto folders and why not, they are all constructed perfectly as far as I'm concerned. In fact a fine attention to detail is an absolute must for creating a folder which will be firstly, safe to use and secondly last for the following generations (IMHO). Their folders to date deliver such philosophy to a reality.
The only disagreement with the website data was certainly no one metre of paracord was included, more like 50cm! Ok that's more than enough and for me it adds ZERO value to the knife. I want to see a great product and a matching great scabbard. In the latter case the heavy Denier Nylon scabbard was well constructed and no lose stitching, frayed ends of webbing or clumsy stitching was noted.
General Characteristics:
Sabre ground
Semi tanto tip
Lock back folder
The spine of the Nieto Ranger XXL is also nicely rounded and it bears a distinct resemblance to other knives in the line up because this knife has been designed by Manuel De Le Torre.
The thick N695 stainless steel blade of the Nieto Ranger XXL (Ro11 G10-ie 10cm long blade; there is another version with an 8cm long blade) features a double sided Fuller which has been milled using EDM. This is a process which can be seen on several of their larger fixed blade models. EDM (Electrical Discharge Machining) process creates a defined plasma, which erodes/mills hardened materials without changing their temper and can be utilized as shown above to mill out tricky shapes which a regular milling tool would not be capable of. This is a sort of "coarse EDM as one can easily see the semi rough surface within the Fuller but I think it looks pretty cool too as well as slightly lightening the blade from an engineering perspective. In fact my son commented that one could strike a non safety match in the groove LOL!
Closed length of the Nieto Ranger XXL is approximately: 13.5cmm or 5 1/8" long, therefore making it easy too carry inside the pocket as well, instead of using the pouch if desired. Note the G10 composite is made in Spain, they make a point of this on their web site, although I have no problem with G10 from Asia. I guess they are saying all the raw materials for the knife originate in Europe.
The overall length of the Nieto Ranger XXL is: 23.5cm. The grip is very comfortable whilst doing hard work upon the blade.
An excellent fully Molle compatible Nylon webbing pouch is supplied as standard and it can also be worn (as seen above) on a regular tactical belt. (note the accessory cord was also supplied and I found that it was just enough for me to tie an overhand knot into one end and place the knife around my neck.
The Nieto Ranger XXL has a blade thickness of approx 4.5mm! There is also a small section of thumb/finger gimping present.
The Nieto Ranger XXL features a hefty spring to hold the knife closed and actuate the back lock.
The scales of the Nieto XXL Ranger are made from the composite G10. The liners are very thick stainless steel at approx 1.5mm thick. Although not shown in this image, the liners are partially milled to lighten the knife.
Perfect match between tang and locking mechanism. No surprise there, Nieto make excellent folders!
The rear tang of the Nieto Ranger XXL features a well designed locking notch set at an angle less than 90 degrees for an optimal lock up and this also prevents any backwards pressure from disengaging the knife, should it be subjected to such forces (outside of normal operation). Note here also the beautiful green liners above the actual stainless steel liners of the main frame.
Nieto Ranger XXL (sounds like a Kebab! "I'll have one XXL please"!) Seriously, this is one hardcore lock back folder.
The strong Tanto tip was easily plunged into (I hate to say it) living Birch tree.
There is also a hefty glass breaker and Lanyard hole.
Unlike totally traditional Lock back folders which are generally opened via two hands, this Nieto Ranger XXL can be opened via the thumb studs.
Well machined and finished in every area of construction, the Nieto Ranger XXL will be a knife you can hand down in the family, or present to a family member or friend with no fear of disappointment.
The steel of choice here is Böhler's N695, which is basically 440C.
No binding with the Nieto Ranger XXL in vegetables such as potatoes (Ok strictly speaking-tubers LOL).
All in all I think Nieto RANGER XXL is one of Nieto's best largish folders to date. It is well presented and the design looks cool as well as functional, opens smoothly with no adjustments needed, straight out of the box, plus it cuts like no tomorrow (ok I've only cut up dirty birch bark and after that cooked pig so far so good!).
Stick around for the full field review, coming to a YouTube theatre near you soon! LOL

Tanev Family Knives T7 in N690 Cryo treated TFK - Т7 (N690) BLG10
Tanev Family Knives (TFK) T7
TFK - Т7 (N690) BLG10
in N690 Cryo treated.
The T7 is a sabre ground small drop point fixed blade suitable for hiking, camping and hunting purposes. A 4mm thick spine and tang provide ample strength and sturdiness, combined with a HRC of 58-60 will give a good field service life. The edge has a double bevel and the finish is as every bit as good as the T8 I tested a month of more back now. IN other words, the satin uncoated finish will satisfy those who seek an uncoated blade for food preparation and the construction comes across as excellent from these young knife makers.
(Optional blaze orange micarta scales)
The thick hide scabbard can be worn either short carry on the belt, via the included dangler or horizontally using the two nylon webbing straps.Leather scabbard is welt constructed and features good thick stitching and a strong looking "D ring" for the dangler. The loop for the dangler forms all one piece of the leather scabbard.
There is a small region of gimping present
Also a lanyard hole, so no chance of losing the knife if dropped into snow or water (provided you have it tied on).
TFK cryogenically treat the Böhler N690 cobalt steel after heat treatment for thorough conversion to a fine grain size and maximum HRC of 60.
4.5" blade length, the T7 feels sturdy and well-balanced in the hand.
The T7's tang is partially skeletonized and the G10 scales can be removed with a 2.5mm Allen key for maintenance if necessary.
The scabbard is a deep carry and the knife as new fits very snugly but not overly tight. Obviously the leather will stretch over time. Due to the flared butt end, the knife is easily extracted from the sheath. If using the dangler, the knife and scabbard can be removed leaving the dangler still attached to your belt.
Like all of their knives, the T7 came with a authenticity card which stated the steel type, hardness range and the sheath material.
Video field review coming soon for the Tanev Family Knives T7 in N690 on BCT

New from Extrema Ratio in 2020, this small lightweight knife, named MISERICORDIA is clearly a tactical knife. At only 4mm thickness, sporting a glass fibre reinforced handle and sheath system, the Extrema Ratio Misericordia also features a "Finger ring" and added glass breaker, for those moments you'll need to smash your way out of or into a vehicle or similar. It goes without saying the edge was deadly razor sharp out of the box.
The Extrema Ratio Misericordia has a spear point and a false edge with a deep double blood groove/fuller plus aggressive finger gimping. It is an easy knife to grip with or without gloves. Plus I have to agree with ER, it can be rapidly deployed from the FRN scabbard as well. The release system is just a smaller version (somewhat better I think in design) than the same sheath retention system for the Giant Mamba and the Contact.
The product is aimed towards the military market and clearly can not transition into civilian fields unlike many of their other "military" type models. Although, there are 2 other carry options which could allow "concealed carry" where legal to do so (like on the battlefield). So in this respect I will be limiting my discussion here to what I see as it's intended purposes.
Worn appropriately, the Extrema Ratio Misericordia can be extracted very fast, either with a reverse grip, blade facing away angled up, tip angled down or extracted with blade facing down, tip facing away and up. Take your pick here. Extrema Ratio are advocating the Misericordia can be used as a primary knife (for sure as it cuts very well) or as a backup.
Despite mentioning the end ring could be utilised by some "martial arts" they certainly go no further as to endorse this use. Obviously it is up to the end user to decide how they will use the Misericordia. It's possible it could be thrown too and or used as one of those, what do you call it? dart things???? (I didn't say it!). You get my point right (no pun intended), with a little imagination I'm sure I could easily launch arrows from it as well after adding a bit of powerful elastic rubber to the ring. Anyway enough of that.
The finger guard (slight gimping present) is long enough I feel to prevent accidental slippage onto the edge. As with many Extrema Ratio Models, the scales are attached with one bolt. The scales in this case are NOT Forprene as in so many of their current models but glass fibre reinforced Nylon (FRN) in a "clam shell" design.
Blade steel is of course metal oxide coated N690 Cobalt stainless tool steel.
Stay tuned to BCT for a closer tactical look at this blade and carry system.

CUCHILLO AITOR 14" SURVIVAL Olivo A classic collector's knife!
CUCHILLO AITOR 14" SURVIVAL Olivo.
A classic "survival knife" and collector's item!
Aitor 14" Survival Knife circa well before 2010!
A classic survival knife design dating back many years. Plus it looks COOL! Like a real knife.
Today I purchased a knife which I have been looking at for the last three years. The same knife has been sitting behind a window in a favourite shop of mine for probably many years, possibly at least 9/10! It is an Aitor knife made after Pielcu took over Aitor, as it sports the serial number beginning with B, this particular one: B025863.
Yes, it is not from the original Aitor series (they made them with stag, micarta, phenolic and Olive wood handles over the years) whereby the serial number would begin with "A", none the less, it has become a collector's item as evidenced by its rarity and crazy prices on the internet. To my knowledge, neither the "A" nor the "B" models are in production any more,
One of my Spanish viewers on BushCampingTools just told me he was issued with this model back in 1980 when he was in the Spanish Special Forces!
The Specifications:
6mm 1/4" spine and tang
Solid Olive wood scales
Brass lanyard rivet
Brass and Aluminium riveted scales
140mm blade, partially serrated (like the early PUMA knives), useful for starting cuts, then to be followed by the regular blade.
There is a more than generous lower finger guard.
Deep belly, perfect for skinning (not too long either), weight forward for chopping if necessary
Spine serrations
Blade serrations
HRC 55-58
HRC diamond imprint on blade.
There are some interesting deadly sharp serrations of a non-standard design upon the spine edge (this design dates way back to their early designs from Aitor before being taken over several times. They would be very good at fish scaling and cutting cords. The tip of the Aitor 14" Survival has a swedge portion which has been sharpened (this was indeed very sharp out of the box). Having such a design will aid penetration for a thick 1/4" blade such as this. There is also a flat portion for striking a baton against.
Weight (it's not light!) 338grams! or 12Oz.!
Full leather scabbard, stitched and riveted construction, press stud retention strap.
Construction
The scabbard looks "wet" because I just applied some leather treatment to it and now the hair dryer to warm it up a bit.
I had to treat the leather scabbard with some quality leather waterproof wax, softener, to "stretch" it a bit to be able to fit the knife, as the leather had shrunk slightly over all those years unused.
Can it cut? of course it can, shown here some wild mushrooms, onions (later garlic, not shown here etc.)
Field test coming soon!
