Extrema Ratio AMF Survival Knife Big and Versatile

 EXTREMA RATIO AMF SURVIVAL KNIFE
BIG AND VERSATILE

I could only show so much in the video review so now you can see more of the stuff which I was and am doing with the AMF Survival knife.

Also, I want to talk more in detail about the design of this blade and especially one simple feature which you may or may not even think about when looking for a good outdoors knife.

The importance** of having the cutting edge coming as close to the hilt/ricasso as possible. Here in this above example, there is no real choil but the blade finishes at the ricasso. This area on my knives I always keep as deadly sharp as possible along with the tip. If any regions could be "less sharp" it would be somewhere along the mid part of my blade.
The item in this image is the seed and husk from the world's biggest pine cone! The Bunya Pine, Araucaria bidwillii., which can easily weigh over 6Kg! These seeds are delicious eaten raw, boiled, BBQed etc. Now in order to extract such a seed you can not easily cut through the seed coat. It must be pierced (where a sharp and strong tip comes in handy) and then essentially busted apart to extract the tasty large seed.

I easily de-boned this leg with Just several strokes of the AMF knife. The knife can be easily pulled apart/stripped in order to clean it properly. Hot water no problems for the Forprene either as it can withstand temperatures up o 130C!

No coating on the blade of this Desert AMF makes it perfectly food safe too and very easy to wipe clean. The burnished finish also is not so reflective (if this is a feature/requirement for end use).

BBQ meat and tropical grown sweet potato cooked on the fire and cut up on a palm bract (lower part of the palm frond, which wraps around the trunk).

The Extrema Ratio AMF easily cut up the cooked meat too. needless to say the meat didn't last too long before it was readily gulped down!


Survival Knives

Mr Mors Kochanski, whoever doesn't know this name regardless of what country you come from, has yet to learn from what this guys has to say about "survival knives"(at least while he is still alive-at the time of this article he is indeed still alive).
Polish/Canadian born Kochanski made/makes, a living from teaching and instructing no BS survival skills to government bodies, and the public. Some may laugh, but those who do are clearly not listening to what he has to say or simply think they know it all, or are of course the typical "armchair survivalist" spruiking  about this that and the other and essentially talking loud and saying nothing. Why to I even mention this guys name here? Well for one thing, about what he says about knife edges. Put here in my words: You want to maximise your cutting edge for several reasons:
1) Simply that, you have more cutting surface.

2)Having the cutting surface as close to the hilt/ricasso as possible, allows better ergonomics in knife usage, whether that knife has a long or short blade, as power will be decreased due to leverage effects the further the object is away from your hand. That's physics and at least in this universe, can not be undone at present!

3) Knives that place a finger choil next to the hilt only extend this "Levering effect" and hence educe the deliverable power to whatever one is trying to cut or carve. Now fact is, if you design a knife with a choil, this only necessitates the need to use the choil in order, once again, to be able to place the hands as close to the blade as possible. 

No matter how good the choil is, our fingers are now dangerously close to the cutting edge, instead of being behind a guard. Now if that choil is not so comfortable and it will be like this especially if milled with acute angles, basically necessitate the use of gloves, just one further extra piece of equipment needed in order to use that knife in an effective way as possible. You loose your gloves??? Or you simply don't have any? Then what?? OR slip and cut your finger, becoming possibly an instant LIABILITY!

From a manufacturing point of view, placing a choil means less work to: hand sharpen edges; no need for a guard/s (ie less material required for the blade);  Milled material is sold as scrap;

Choils can of course be milled in order to place a greater weight distribution towards the tip of the knife, so that knife, if hefty enough could be used to chop with. Having a choil in this case I believe is secondary to the primary aim of this type of design. 

Even if you haven't been to Australia or even have a desire to come here, I would highly recommend the reading of tis book by A. B. and J. W. Cribb published in 175 by Collins and then in 1976 by Fontana, if you are serious about survival.

No need for a finger choil to be present on the AMF Survival knife. 

These days many manufacturers tend to over state the blade lengths or rather we have become complacent when we read about blade lengths and too many definitions of where the blade starts from. So we have then manufacturers stating the actual "cutting surface".  The Extrema Ratio AMF Survival knife definitely is sporting a good 8 inches of "cutting surface" LOL!
