Thread: Anyone use diamond slurry?? I have some, but don't know what it's for....

I recently bought a bottle of diamond slurry from US Products Co. Type DW-1/4H. Net Weight 50 grams, Concentration: Heavy.

My question is, what the heck do I use it for? I thought I was buying diamond slurry to refresh my diamond paddle strop, which I don't really have a clue how to use either. But my diamond paddle is clean and white felt, and this slurry is dark and brown. Obviously not what I thought I was buying.

So, has anyone actually used any of this, and is it supposed to be used during a specific honing stage or what? I got it from a shaving store online, so I assume it was for sharpening razors at some point.

Any thoughts???

Thanks in advance,

Mike

I suspect the stuff is designed for some heavy duty polishing work. What's the grit of stuff? or micron size?

I believe I purchased the .25 micron, there were only 2 choice, .25 or .5, and I think I went with the finer of the 2.

Have you any idea how it's supposed to be used? As brown as it is, I suspect your supposed to add it onto the surface of a hone as you work it.

Your thoughts sir?

Thanks for the reply!!

Just found reciept, and indeed it was .25 micron.

Hello MJhammer,

you have some very basic questions there. Maybe you should do a little more research on diamond spray, pasted strops and similar before you ruin your strop or anything

First of all your felt strop may be impregnated with a diamond spray already depending on where you bought it and what you chose.
You should check that. If your felt strop has already been impregnated with diamond spray you should not have to refresh it.
Usually these felt strops last ages. If you notice the white felt has gone a bit dark from cut steel, or doesn´t polish anymore you can refresh them.
With normal use I should think not before after one year of use.

If you chose to impregnate your felt strop or any strop you want yourself, it is recommended to use sprays and pastes from known vendors to prevent any mistakes
since once impregnated your strop can not be un-impregnated. I don´t know what source you got your diamond spray from and if it has the quality standards we need (how many particles above and below 0.25µm are present etc.).

But if you have a product of high quality (actually I don´t know the manufacturer, but I``m sure others do) 0.25µm is a very fine finishing stage.

If you want to make your own pasted strop, just spritz the strop with a very, very light and thin coat. The diamond will cut very fast anyway, so no need to overdo.
For a felt strop 2-3 spritzes usually do the trick

I forgot:
Yes you can use the diamond spray as a fine slurry. But beware, the diamond particles are mixed in an alcoholic solution that may, or may not attack certain types of binders in stones.
I would recommend using it with caution and diluted with water i.e. on the wet hone do one or even only a half spritz to add some diamond particles to the water forming a slurry.
This might improve the cutting speed and depending on your stone improve the polish of the bevel. You can try the slurry on your finishing stones, like a very hard and dense natural (Chinese 12k and such).
But this technique is rather not common
