Good heft; feels like you have a great piece ...
Review by Kinara U.
Verified Buyer
Very substantial knife! Good heft; feels like you have a great piece of steel in your hands. Did not cut paper out of the box, but I did not buy this to make sushi; i have high carbon Japanese knives for that. I hike a lot in the woods and I wanted a knife for protection in the event (hope it never happens) an animal attacks. After having a dog with huge teeth charge me in a park, as I stand defenseless, I decided that I need something for the woods instead of the pocket knife I always carry. I wrapped the handle with some tennis racket handle tape for added grip.

When I spend over $100 on a knife I expect the blade to be perfect not damaged
Review by Christena G.
Verified Buyer
The reason I am giving a 3 star review is the fact that when the bayonet arrived there was a huge ding in the blade. Took me about half an hour of stone work to fix it. When I spend over $100 on a knife I expect the blade to be perfect not damaged.
The real thing.
