Pin Head Spinning

Dec 26, 2012
I'm curious about this method of spinning pins on a knife. More so for the traditional type folders. I've repaired several of my old slip joints and so far ive only used wood and micarta for the scales but now I'm interested in using stag and jigged bone. The only issue with that is peening the pins. I haven't been able to find much info on the head spinners so I'm wondering how some of you accomplish this process. Do you buy your own spinner? I know that some make their own from tool steel and I'm interested in that. Any pictures or videos would be very helpful. Thanks!

Pin head spinning is done to some factory knives as a fast-production method. That is the only advantage.
Unless you are trying to duplicate the factory method for some reason, spinning pins is unnecessary.
Peening the pins is easy. Stag and bone are stronger than wood, and careful peening will work very well.
Thank you for the reply, Bill. So how do you get down into the groove of the bone or antler to peen the pin? Do you use a hammer with a tiny face on it? Or a punch?
Bone is no problem to peen, as the jigging is not deep.
With stag, you can use a punch, or file the stag down in that spot. Most of the time, you can just use a hammer.
