Actually, you can take a pin, like a safety pin.....heat the tip with a lighter and touch it to the area your testing....if it smells Like plastic, you'll know. You want to use the smallest pin possible! Its not a big deal though!!
I can tell by looking its a Delrin Handles (plastic) I own several Queen knives and knew immediately when you listed it was a Queen knife their Delrin patterns are quite distinctive
Yes, but I prefer the term "Composite" Just sounds better, ya know? But you're right, Sageani. It's plastic, very durable plastic. Beautiful piece! Watching.
I usually peruse listia looking for old slipjoints to refurbish. I found this one, but there is not much I can do in ways of cleaning it. Respect for keeping a knife in excellent condition.
