Can you Strip the Coating on a Cryo or do you have to sand it?

[gentemanndvm]

hi all,

My Bladeforums SearchFu is weak today, so i need help. I found a couple threads that talk about sanding the Cryo's coating off, and that's it. is that the only way? i'm kind of digging the idea of a satin blade on one.

From what i found, the TiNi coating has an RC of 494 billionjillion (ok, 83-85 ) and you HAVE to sand it off. But other threads talk about it wearing pretty quickly with use. I'm just hoping for easy.

If I do have to sand it, think i could scotchbrite it off, or would i have to actually SAND it off b/c of the hardness of the coating????

thanks in advance for any and all expertise!

I was wondering about this as well. What about chemically removing the coating?

Scotch brite works well to remove the coating but will not leave a fine polish. Make sure to go in one direction because it will leave lines behind.

PCB Etchant Solution will eat right through it as well.

PCB Etchant Solution will eat right through it as well.

If you use that, protect the edge, for sure. That stuff keeps eating away at metal until neutralized.

thanks for the responses so far!

orange, i can take it apart to do just the blade, but i just realized i also have the thumbstuds to deal with. they don't look like they are coming off easy. ever taken those off before without scratching the bejeesus out of them? protect the metal and twist in opposite directions with 2 sets of pliers?

biggie/mrn8 - would i lose uniformity of surface by doing it with pcb etchant? would it be like the gunblue/bleach method for etching blades where you get random patterns of etched metal out of it? love that on my Becker's, but don't want that on this knife.

I'd assume making it warm would help too.

I didn't take the studs off when I did mine, but I also left the rest of the blade between the two grinds its original color. I have since stonewashed it or I would take a pic, but it looked pretty good that way.

Look at my post on custom cryo. mioduz and I do all kind of different things to the blade. I'm not sure what looking your going for. I really like the stonewash look. It really highlights there grind lines.

With using the acid your going to need a good sharpner because you don't want to protect the edge to give it a uniform look. But you will need to protect the pivot area. After the acid you could hit it on a buffer to give it shine and a uniform look.

Problem with sanding is the line in the grind lines get rolled. We had someone send us a knife that the blade was sanded. I feel that the highlight of the blade is the grind lines.


Also the thumb stud come out pretty easy. Pliers and some cloth does the trick.
