Question: Where can I find an 8 inch Kydex sheath?
Document: The Kydex sheath doesn't come with this model, instead it has a nylon/leather sheath. I can't say yet how this will hold up to the elements, but I wish it had another tie-down on the blade end. It's easy enough to make one, however. Overall, this is everything I expected it to be!
Looks to be a great knife. I have yet to put it through it's paces, but I'm impressed so far. Out of the box the blade is razor(seriously) sharp. The handle is very comfortable and it has a good balance. My only reservation is with the sheath, seems a little flimsy. I would prefer a kydex sheath, but don't think a factory one is available yet. This one won't fit the other model sheaths as the blade is wider. overall, I'm very happy with it.
To top it all off, Ka-bar does not make a kydex sheath to fit this knife. The blade is to wide. Seriously people throw me a fricken bone here. Rated four stars because the knife is awesome.
much cheaper here than other places online i checked. i couldnt find this one in any stores in my area. overall the knife is great!! i couldnt be happier with it. the blade holds an edge well, is well weighted for light chopping and the handle is great quality. i wish it had an all leather sheath but the sheath it comes with is pretty kickass. the guard is thick and good quality.
I own 2 and got one for my future wife a while agoand now one for a good friend. This knife is awork horse, you can use it for a whole scope ofThings and most of the time it delivers. Digging,Cutting off branches, light chopping, shaving,Get creative! If you love outdoors and carry aPocket knife..... try one of these fixed blade 8"You won't go camping without it again.
Only my personal preference for the appearance of the knife made me send it back. I go for looks and quality in one piece and I didn't find it on this one. I recommend buying this if you like how it looks like and you also love it's quality. Money well spent. [I bought an Ultimate Arms Gear Multi Terrain Camo Tiger Stripe finished M9 bayonet instead.] At least I love how it looks like even if its not made of carbon steel. I will not pry hard with it anyway.
All the quality you expect from a standard Ka-Bar but bigger! The rubberized handle is tacky, with a secure grip. The blade is quality steel and sharp, did I mention that it's bigger. If you are a fan of large knives you will love this blade, though not as massive or heavy as a Rambo knife  it's and inch longer than standard, and wider, yet still quite useable. I give two thumbs up!
Very happy with the quality of this knife. I recommend it and have purchased two. The knife came very sharp and the sheath was quality also.
I have been wanting this knife for quite a while.When i pulled it out of the sheath I was very impressed, very solid feel to it. The knife maker for the U.S.M.C. & made in the U.S.A.! I highly recomend this knife, it will last a lifetime.
The knife is an excellent knife. Arrived very sharp. It is well balanced and accurate as a throwing weapon. The sheath supplied with the knife is another story. The sheath is shoddy and Ka-Bar should be embarrassed to send this sheath with this knife. All in all though I am very pleased with the knife.
