Can't limit it to one. Will limit it to knives I own, which leaves out the LCC, the 710, and the Timberline Vallotten Discovery Lock.
Mine, in no particular order:
CRKT LUS
CRKT KFF - large
CRKT Companion
Spyderco Wegner -- if it was in last 3 years
Spyderco Native
Outdoor Edge Paragee
OE Magna
OE Impulse
Thus far, IMHO, the Edge Tech division of Outdoor Edge has hit nothing but homers. The Paragee is much like the Camillus EDC. Except less expensive and better. The Magna is a brute, with fine fit/finish. The Impulse has so much style it is easy to overlook what a good, versatile knife it really is. All are tremendous bangs for the buck.
My Sebenza was born in '99, if that counts.
Welcome back!
