Thread: Where to get .5 micron CrOx paste?

I see on SRD they are out of stock. I did see something on Amazon, Green Chrome Oxide Compound, 6 oz. - Sharpening Stones - Amazon.com

Seems like it might be .5 micron due to the Q&A, but wondering about quality. Any other recommendations for sources?

I have a 2.5" wide black webbed and leather strop from SRD. Should I use this on the black webbing (I think a video from Lynn said I could), or should I use the rough side of the leather?

I'm thinking of getting a 3" bench or paddle strop, as I think it'll take away some of the variables with learning to strop well. I liked the modular paddle strop from SRD, but alas, it is out of stock too. I was thinking I could use the strop I have for pasting, and the bench/paddle for day to day stropping.

Suggestions?

If this is the one you're talking about I'm about 99% sure it's .3. there's a chance I'm wrong though. Did a quick search everywhere and its either discontinued or out of stock. Sorry brother.

oh but good sir is in luck because one person would find verry hard to use one of those crayones up in his lifetime and I just happen to have one. so if he would like to send me his address i would like to send him an oz of it and that should last him a lifetime

I like this stuff but think its finer than .5

here you go

Don’t know about either of those, I have only used SRD crayon, Hand America Spray and Liquid and powder from Kremer Pigments.

Unless it says it is pure or 99 percent it probably is not. Once you apply Chrome Oxide to a substrate, you will never get it all off. So choose wisely.

Most Chrome Oxide sold for polishing contains other abrasives larger than Chrome Oxide.

One of the biggest mistakes people make with Chrome Oxide is purchasing paste that is not pure Chrome Oxide, Second is applying to a hard substrate and Third is using too much pressure.

It is not expensive and a life time supply so buy only quality Chrome Oxide that has been used for stropping razors.

If you want to experiment, make a paddle strop from a 3in piece of foam core, dollar store foam core is rougher paper and works better. Finger paint on 3 in x’s.

Impure Chrome Ox will leave a rough edge, as will excessive pressure.

You might want to do a bit more research on the Formax crayon

That is for buffing, and it is not near pure enough for stropping a finely tuned SR

There is a ton of info about it here on the Forum including MSDS sheets

Almost posted that but it's discontinued

And I don't know why I didn't think about it but I could definitely send you a chunk of mine as well. How selfish of me. Just let me know.

There's also the option of .3 micron lapping film.

I personally like .50 micron diamond spray, because it is less messy. What I do is use a linen strop other than the one I use every day to put this stuff on, because I only use it for touching up.
