Hi sladey!

I'd suggest to not seddle on just one knife (despite the weight issue). I carry a Folder (Al Mar S2K) or the F1 along with the Becker CU7 or A 1 along with a SAK Huntsman. Depends on the environment I'll aimed to and the mood I'm in at the time I prepare.

If you're looking for just one Knife as kind of allround-tool I'd suggest something like the TAK, S1 or similar. There are a lot of very good medium sized fixed blades around.

Adding a sharpenig device won't be a bad idea either IMHO.

Take care
