Welcome Kristi! Nice to have you here.
I still have my first Spyderco knife, which I purchased at an IABTI conference in the early 80's. I used it for many years in LE EOD work. I found it's one hand opening invaluable. I see now that a few Spyderco's are equipped with a 'wave' action assisted opening. I like the wave action.
Do you still send people to the IABTI International conferences?
