i carried a case trapper in CV for a while, then switched to an opinel #7 for a while, and have yet to turn back. the opinel is really great, in terms of pure cutting power and in terms of a great deal. one of the things i like about the opinel is all the blade you get in such a small package. alot of folders have blades that are quite a bit shorter than the handle, but with the opinel i find myself wondering how the whole blade fits into the handle so nicely.
the locking-closed thing is also nice, for when you drop the knife or other things...and the round handle really feels good in hand. when i went to use my trapper again yesterday, i found the handle very boxy and thin. it made it a little hard to hold onto.
SAKs are also very good deals, especially the thinner, simpler models. alot of bang for the buck, and they have enough tools to fix just about anything.
