I have an Al Mar SERE 2000 lock knife in pretty good nick that i would like to trade for a green goretex bivi bag (either Brit or Dutch). The knife has been lightly used and sharpened twice, a few scratches on the blade etc but its still very good. The bivi bag should be in very good condition, definitely no holes or tears. Here is a link to some info about the knife:
