I have kept the same Gerber multi tool on my hip for probably 15 years of camping & canoeing.  I have no idea what model it is, but it holds an edge well, and the needlenose can be easily extended with one hand while the other hand holds a fish.  The phillips & flathead screwdriver blades are decent.  I do not use the file or "saw" blade much at all....and I still have no idea what the round thing with the hole in it is for....other than that, it hit 'old friend' status years ago as far as gear goes.
