Thread: Divot in anvil size

To the guys using a piece of steel (or whatever material) as an anvil to peen their razor pins, what size divot have you found works best to rest the opposite side for the hammering in? I can't remember what I've used, and I have a project that I need to be right the first time.

I use no divot .

Thanks Bill. Do you find that it flattens the rounded look of the downside pin face at all?

Btw, I read your reply in a very heavy, fake sounding Russian accent for some reason. I think I need sleep.

I polish my pins after peening,It may flatten them a tad but has never been a problem

I find that the divot does more to hold things still than it does to round or flatten the pin. But a nice advantage is that if you drill to a proper depth, the hole can serve as a guide for when you cut the rod to size before you start hammering. There are other ways to make that measurement, to be sure, but I think that is a slick way to do it.

Yes, but what is that correct size/depth? Lol.

Here's what I'm making if anyone is interested.


They are A2 tool steel. The one in the left its where I'd put a small divot. I don't do many razors anymore, but I figured if I'm making them, I might as well make them to encompass everything I do. The one on the right needs a couple holes drilled in the back of it, for pocket knife pins to be driven out of the bolsters. The will be mounted to a piece of 1" mild steel. If anyone knows of a cheap heat treater, let me know. They need to be in the low to mid 50s Rc.

I wonder what the RC is now? Tool steel is often used without being heat treated, so you may not need to do it.

I expect it depends on the washers you intend to use and how much you mushroom the pins over them, if you mean a shallow divot for resting the razor pivot pin in while peening over its opposite end during final assembly. Do you have a razor and a micrometer that you can take a reading from? Mine works out to around 3.54mm dia by 0.96mm depth, but yours may well be different.

If you know a jeweller or a potter who has one of those little electric kilns, then they can be used for heat treating.

Then one can always add a little touch to the pin heads by engraving the divot and a matching striker.

Yeah, it was really more tongue in cheek, making fun of myself. I have a set of calipers that will work fine for taking measurements from the four out five razors I have around. I don't know why I didn't think of that sooner. Lol

Unless I can find an experienced heat treater in this forum or BladeForums that will do them cheaper, I'm planning on sending them to Peter's Heat Treating out east. They do really well with my knives.
