Looks like your knife is still going strong, looks like a good design for intended purpose But, in MHO no knife that may be used in the back woods in a survival situation should be without a GUARD, for the same reason as in the photo, this could have ment the difference between life or death. Also remember that the best tool for survival is the one that you have on or with you, tools (knives) can get lost, out of packs, watertight bags, or pockets, ask me I lost my Chris Reeves folder yesterday form my waistband while Kayaking on a local creek, loocked the rest of the day for it with no lock. Good Knife had it with me everday for the last foue years, loved it and will start saving for another one, surcure them good Gents.
Also, I agree with Nick, looks like blade not completely hard on cutting edge, but all that can be worked around, would like to know what steel and how it was made.
