Here's what works for me.

Around town:
1. utility pocketknife - Victorinox Alox Farmer

Dayhike:
1. utility pocketknife - Victorinox OHT
2. medium/large fixed - Camp Tramp (or SFNO if you don't mind the weight)

Out for a week in the woods:
1. utility - Victorinox Swisstool
2. small fixed - Scrap Yard SS4 (or AD or MS)
3. large fixed - Swamp Rat Battle Rat (or NMSFNO or FSH)
4. saw - Silky PocketBoy 170

Add for car camping:
5. axe - Gransfors Bruks Small Forest Axe
6. big chopper - NMFBM
7. bow saw - I got mine at Ace Hardware

That's my setup. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
