Bear Grylls Ultimate Knife vs Gerber ASEK LMF II Comparison

Bear Grylls Ultimate Knife

The Bear Grylls Knife certainly was not razor sharp when I took it out of the package but after a fewMan vs Wild Knife Review Gerber swipes on the integrated diamond sharpener (that is included with the knife) it was easily taking hair off of my forearm.

The second thing I noticed was the rubber grip. It was very comfortable and shaped to feel right at home in my hand. It made quick work chopping out a notch in a 2 x 2 wood board that I had lying around as well as some fallen limbs in my backyard.

As for fire starting, it shaved slivers off branches with ease and it was just big enough to use as a draw blade. After creating a small pile of fire tender, I used a small portion of the back of the blade designed to be used with the striker to get a few sparks flying.

At first I was worried that the striker was going to be too small compared with the size of the knife but it worked just fine and within seconds I had a little fire going. The fire starter is a nice feature that it snaps right into the sheath.

Next, I used the pommel to drive a 3 ¾ inch nail into the 2 x 2 wood board, which it did. It was slightly gerber ultimate knife review man vs wilduncomfortable holding it with the tip of the blade pointed upwards and driving the handle down like an ice pick, but it worked.

The whistle which is attached to the pommel got in the way while I was trying to use the knife. I will probably end up taking the whistle off and attaching it to the sheath. The whistle is of lower quality and far from being a Jet Scream Whistle, but it worked.

The pocket guide is a nice little touch and it “tucks” right into the land and air instructions on the back of the sheath. You’ll have to pry the rubbery pocket to stretch it so the pocket instructions will fit. However, it has the main basics skills you would need to survive if you were lost for a bit and it is always good to brush up on the basics.

Pros

  • Comfortable
  • Easily sharpened
  • Fire starter, sharpener, whistle, pocket guide included
  • Affordable

Cons

  • Whistle gets in the way
  • Doesn’t feel as durable as the ASEK LMF ll
  • Sheath durability

Gerber ASEK LMF II

The Gerber ASEK LMF Survival Knife has some heft to it, not heavy but you definitely know its there. This weight ultimate knife reviewcame in handy when chopping notches and also hammering the nail.

In order to hammer with this knife you have to have the blade side of the knife in the palm of your hand so remember to wrap something around it before you start hacking away.

This knife too is quite easy to sharpen with the sharpener that is integrated into the sheath. The extra rope cutter/skinner I have only used to cut 550 paracord, which it does with ease. I like the sheath system on this knife better because it has two straps so that you can attach it to your thigh but they are removable if you want it attach to your belt.

Pros

  • Feels solid and durable
  • Performs all knife functions great
  • Sharpener, cord/gut hook included
  • Can be worn on the beltline and attached to the leg

Cons

  • Not as comfortable in the hand
  • More expensive

Wrap Up

Even though when the Man vs. Wild TV show first came out I was an avid watcher, I have grown a little bit tired of it man vs wild survival knifeand was a little skeptical of what the Bear Grylls Knife would be like. If it hadn’t been made by Gerber I probably would not have spent what I did on it, but I am glad that I did.

I have not had the chance to properly field test it over a few days in the woods I think it is a tough knife with some nice extras for the price.  If you are looking for a new survival knife or just add to the collection I would recommend the Bear Grylls Ultimate Knife, for the money it is a decent knife.

However, if price is not a concern I would stick with the Gerber ASEK LMF II. The knife and the accompanying sheath feel more durable and I think it will serve you much longer.
