Benchmade large Griptilian. I bought it used, and I've really put it through the ringer.
Two old Spyderco first generation Enduras. Beaten & worn down, but both still cut pretty well. The last 1/3 of the blade on the fully serrated one will slice paper (after I filed the edge back to a decent profile.)
A "Franken-dura" &"Franekn-Delica". Both are hybrids: Standard models, with scales from other models installed.
Some little generic give-away knife. Pretty much indestructible. One of the most ergonomic knives I own, believe it or not.
U.S. Schrade Old Timer Folding Hunters. Still working hard after decades of use. Some of the best steel ever put into knives.
Beat up, well-used old kitchen knife, sold in bulk by Shapleigh Hardware decades ago. Takes a better edge than any of my newer kitchen knives.
Case large Stockman, with CV blades.
A couple of old Stockman patterns, with bone scales.
Finally, the two I'm most honored to own: a Camillus TL-29 that belonged to my maternal father, and a Schrade-Walden Rigger's knife that belonged to my paternal grandfather.
