Ditto on the Buck Zipper. I bought a special model, made of ATS-34. Supposed to keep an edge even longer. Only used it to dress one deer this year, but it held up very well. It' s just a tad bigger than what I usually like, but so far it seems to work just fine. I just wish someone would make a knife with a blaze orange or yellow handle, for when you set it down while field dressing. Sometimes it get slid under the leaves, and can be hard to see. Since your knife is the most valuable tool that you can take in the woods, I haven' t figured out the reasoning behind camoflauge knives, yet.
