EXTREMA RATIO Dobermann IV Tactical Version (Black blade Molle Carry System) Review
 |
| Extrema Ratio Dobermann IV |
When you pick up the Dobermann IV you know it is the evolution of some serious R and D (actually it is! with the University of Florence and Perugia University) to deliver a large practical field blade. You simply can not help but like this big general purpose field knife. The comfort of the ergonomic handle, the well-balanced blade geometry, with it’s ever so slight recurve shape on the cutting edge begs to be used establishing camp (hanging game up etc) for medium to large game hunters in remote (without vehicle) and wilderness campers for some serious adventure.
The blades are serial numbered
which enables EXTREMA RATIO to trace each knife should in the unlikely event a manufacturing problem should occur. This to me says the company is serious about making excellent products. Let's have a closer look:
The spine is a good 6mm thick, with swedge but the spine thickness is still the full width almost to the tip. No need to say it was deadly razor sharp out of the box, of course it was EXTREMA RATIO are serious. The feel and balance as I've said was fantastic and this is from that ergonomic handle. The handle provides an amazing grip. A cutaway area of the handle serves as a thumb/finger rest. On a large knife it's not really necessary for this area to feature gimping and in this knife you are not going to be slipping with your grip. Just to reiterate, the handle is FORPRENE with a shore hardness of approximately 80 to 90, soft enough for good comfort but hard enough for good mechanical durability. See my previous posts about FORPRENE'S specifications.
The semi rigid scabbard is great too, with a 6 year warranty! It's totally fully Molle compatible and the stitching and construction was of very high quality, nothing flimsy here. The carry system includes a well designed fully adjustable leg strap. (not shown here only because I took it off!) I'll review it properly in the upcoming videos!
The safety press stud strap is reinforced with a strip of hard rigid plastic. I liked this idea but it is also a necessary one as when one removes the Dobermann IV
unless you position this strap out of the way, the blade will tend to rub against the strap. This is ok as it won't cut it but it's easy enough to get used to moving with one hand the strap out of the way as you remove the knife. The Dobermann IV comes with a spare knife retaining strap.
Specifications at a glance:
Knife + scabbard (excluding leg strap) 542 gm
Knife alone 351 gm
blade length as measured from hilt 180 mm
Actual cutting edge length approx. 175 mm, so it's close enough to the actual blade length.
Verdict: actually been using this knife for a while now, forgot to post this LOL so many things happening! Love this knife.
