Friends, lurkers, and fellow Knife Knuts,

In another thread, the infamous Chris Reeves Green Beret knife was somewhat disparaged as a wilderness/survival knife. One of our beloved moderators noted that while the GB had been tested in laboratory conditions, the tests were not helpful in evaluating the knife as a wilderness or survival tool.

Good point.

So I proposed to test the GB in ‘closer-to-real world’ conditions. I didn’t want to completely hijack the other thread, so I thought I’d start this one and add to it as I put the GB through 'Field Trials.'

Let me say here in the first post, that I am not advocating for this knife.
I do like it, but I think I recognize some of it’s limitations. It was designed by Bill Harsey in collaboration with soldiers and is designed for some of the most extreme soldiers in the world. Their needs may be different from yours, that's understood. Having taken a survival course run by special forces soldiers and worked with a few SOF guys, I can testify that they understand a few things about survival. I can also say they rarely agree on what makes a good knife.

Nevertheless, I like this knife enough to have sent one to my brother when he deployed to Iraq with the Army—he loves it. I got the one pictured here when I was preparing to deploy (although that deployment was canceled.). Anticipating my next deployment, I got Bryan Breeden to make a knife to my specs (Hey, Special Forces guys don’t know everything.). So I hope my bias is now fully disclosed.

First let’s talk about the knife.

445142581_kj9Av-M.jpg


I stole these specs from the CRK web site:

Blade: 7” full tang made from 0.22” CPM S30V, hardened to 55-57RC, and coated with KG Gun-kote. As pictured, there are 1.5 inches of serrations after the ricasso. The blade is hollow ground. The swedges form a false edge for the last 1.5” of the blade.
Handles: made from linen micarta, they are undersized with respect to the tang, leaving the tang protruding about 1/16” out of the ‘handle’ all around.
OAL: 12.375” with a weight of 12.8 oz.

But enough of my blathering on and on. So let’s do some testing.

I have a list of tasks to try out, but I will entertain requests. This is not a ‘destruction test.’ I have a soft spot for old Ford 150's. I like the knife and reserve the right to preserve it. But if you’d like to know how this knife performs a certain bushcraft task, I’ll try it out.

If you disagree with my conclusions, please post. I’d like this thread to be a constructive debate, and not just me ranting away for 8 pages...although I’m willing to do that too. :D

Here is my list of tasks:

Food prep
Chopping
Carving
Batonning
Cutting
Fire starting
Skinning (hunting Gods permitting)

I’ll add to this list as I go, suggestions welcome.

Now, for my first test, I tried dealing with my most common survival situation: Lunch. Food prep is probably the most common use for a wilderness knife--from spreading peanut butter to opening MRE’s, the knife reigns supreme.

Today’s challenge was….the sandwich (cell phone pictures, sorry).

The serrations really bit into the bread and sliced it open cleanly. Slicing bread is not a bad test of sharpness, a dull knife will squash and tear bread. This knife sliced like a lazer.

Not shown is the excellent spreading ability—the long blade made Russian dressing distribution a snap!

OK, a bit lighthearted, but still, that’s a heck of a sandwich (recipe available upon request) and I survived only to live through another meeting.

I understand that the pineapple test is becoming more popular.

The GB proves to be as tough as a Breeden in this batonning test. In actuality I was able to remove the outer layer surprisingly well for such a thick-bladed knife. Used the GB to cut the pineapple up into a 1/4" dice for salsa and it did fine. It's no chef's knife, but it did fine.

OK, some whimsical (but still demonstrative) tests done to kick this threat off. I'll do more as time permits. Don't know about you guys, but I'm having fun already.
 
thanks for the review,,

been looking at one of these for awhile now,,
 
Great write up so far and now i am hungry for some pinapple LOL
Keep these writes up comming I like um LOL

I would like to hear more about its spreading capabilities. I mean you tried it with Russian dressing, how about something a little more challenging like say some chunky peanut butter :D

Surviving meetings is very important and has been the height of my wilderness experience for the last few weeks :grumpy:

Excellent thread idea and nice first post :thumbup:
 
Terrific. I will stop over with beer if you make the sandwiches. Football playoffs are coming!
 
How do we know said knife was actually used. N*&# actually filmed his tests. I assert that you used a Busse on the pineapple and a Ginsu on the other fruit pictures.

I for one will not be continually haranged by you folks who feel they know what a combat knife is used for. Having personally hacked an I-beam in half and then filleting a Brown trout seconds after with my GB, I see no more use in discussing these so-called tests. :grumpy:
 
Haven't had time to do much with the GB in the last couple days. Hope to get out some this weekend.

I did use it to make a couple fuzz sticks.

446648806_9hyZz-M.jpg


And a figure-four trigger. (Actually 2 figure fours, unfortunately I broke the first one when I sat on it. LOL.)

446606723_DKJps-L.jpg


No snare set on the figure four. Guts from 550 cord used for cordage.

I just wanted to get a little more experience cutting and carving with the GB. It cuts aggressively as you would expect with a hollow ground blade. Edge retension seems reasonable. After carving up several sticks and making a couple figure four traps, the blade would still cut hair. It wasn't hair popping, but a few strokes on a strop brought the edge back.

One limitation with this knife is the upper guard. I have a habit of choking up on the blade and putting my thumb on the spine for extra power and control. The upper guard digs into my thumb when I do this.

446606805_tePVW-M.jpg


This can be rectified by rotating the thumb over the guard and putting it on the side of the blade. This worked best when I braced the knife arm against my body.

446606861_twFWp-M.jpg


Another limitation is the serrations. I like using the heel of the blade for tight controlled carving, but that's where the serrations are. :grumpy: I wish a plain blade were an option with this knife.

Overall, the knife carves well (I'll try a spoon when I find a good piece of wood.). The blade is sharp and can make fine cuts and curls.

I know you guys want to see some more aggressive stuff like batonning and chopping; with a little luck I'll create some wood chips this weekend.

Cheers,

R
 
Great testing so far Rotte. I like the blade. Seems to be performing well for you so far.
 
Excellent posts! Don't underestimate the rigors of the pineapple test ;)
 
If im not mistaken isnt the GB actually issued to special forces "green berets" upon completion of the course?
 
I thought the GB and the Yarborough were the same; the Yarborough has engraving.

So imagine you are stuck out in the woods with your trusty GB and a can of peaches, but without a Victorinox SAK. (I know, it's an impossible scenario, but imagine you don't have your Vic with you. Yeah, your back-up Vic also got stolen by ambitious field mice.) Will you starve? No.

Here's another practical 'test.'

446786040_BVYRD-M.jpg


Mission accomplished:

446786170_emRGp-L.jpg


No surprise, the GB can serve as a can opener in a pinch. (The technique, for those of you who have never done this, is to place the tip of the knife on the can and use the heel of your hand to smack the butt, thereby driving the tip through the can. Rotate the can and repeat. Careful! Lots of sharp edges now.)

Zero damage to the tip. The leading edge of the knife was slighty dulled, but came right back with a few strokes of the ever present strop. The Gun-kote coating did sustain a few scratches however.

(Peach crisp for dessert tonight :))

For those who are familiar with the Fallkniven A1 and GB, how different are the bladeshapes of these 2 knives?
