Lots of good ones out there and mentioned here, but You should look at "Boker" also known as "tree brand" One of the very best out there. I'm on my second, as a cave in Montana seemed to swallow my first. <img src="/forums/images/graemlins/angry.gif" alt="" />
Also "United Cutlery" is well known for providing a very good product.
Search Ebay under the name of "Colt" and in "knives/swords" Colt has several models made by United and they are also very good.
Boker, and United Cutlery have made many knives for our military/special forces. <img src="/forums/images/graemlins/patriot.gif" alt="" />
