I think you should buy some mora's as previously suggested. Give them out as loaner's. They are light and cheap and if you loose them or break them it's not a big deal. Also they are great knives.

If you want to wade through some knife review take a look at this website:

PS I still stand by my swamp rat recommendation they have a user enforced quarantee (you tell them if you want the knife replaced not them) they also have a penetrator tip which I think would help you in digging out arrows. <img src="images/graemlins/smile.gif" alt="" />
