Thread: diamond foil and other interesting stuff

I came across this product today, it seems rather useful.

Yes. Not cheap but really handy.
I uses similar from Atoma for truing the ends of carbon arrows. A small square stuck on the end of the arrow squaring tool as below.

I've wondered if something like this was available that could be used to remove pitting more quickly by hand. Too rich for my blood though!

Actually, it's not that bad really. Because these things last forever if you treat them right.
Sandpaper is just thrown away. And really, the one you need most is the 120 or 150 grit, for removing pitting. That's the real work. You can still do the polishing with sandpaper.

Since these are 2" x 4" sheets, the pricing per square inch is not much different that an Atoma diamond plate. For restoration, I can see these being useful.

Especially since they can be adhered to a cork or dowel to closely match the contour of a blade.

Didn't realize they were that durable. I haven't done all the reading so I was sure how long they lasted. If I ever get back into restoring regularly I may have to try this out.

I won't say they will last forever. But like a DMT or atoma diamond plate, if you treat them right, they will last a very long time and perform consistently.

the CS-HD polishing stones for hardened steel may be a great option also, the kits are cheap enough 1/8" x 1/2" x 6" of each size
or single stones go up to 1" x 1" x 6" bit more expensive but

Compared to the CS or CS-M, the CS-HD is harder acting and slower to break down. This polishing stone can be used to polish even the hardest die and mold steels. Polishers claim excellent results with the CS-HD when finishing dies ranging in hardness from 47 to 63Rc. Some mold makers also use CS-HD for removal of EDM.

Just the thing for doing the back of Jp. single bevel kitchen knives.
Got something similar locally but they wear down pretty quick.
