I cycle through a host of EDC knives, sometimes picking one in the morning that suits what I'll be doing for that day. Today, it's a ZeroTolerance 350. Other days, it's one of 12-14 knives from the display case in my office. The ones I carry most frequently, in no particular order, include:
1. Strider SnG
2. Blackhawk Crucible
3. ZT 300 Special Edition
4. Kershaw Mini-Cyclone
5. Kershaw Steven Seagal
6. Hinderer XM-18
7. Benchmade 940 Osborne
8. Spyderco Chinook
9. Spyderco Manix
I carry the others (having trouble remembering them all!) but this is my "top 10" list.
Specialized
There are a few others, but those are the ones I typically carry.
