Another ditto on the F1 and a SAK. The F1 as mentioned above can be had at Knifeworks for $86.95. Good deal. The SAK scissors and file can be real handy on ragged nails. The tweezers are invaluable for splinters. If you foresee chopping, bring a small hatchet as others have said. The SAK I like best is the Fisherman from Victorinox:http://www.knifeworks.com/index.asp?PageAction=VIEWPROD&ProdID=6578. The Climber and Huntsman are also good picks.
