Hello everyone,
I really like to hand America 1 micron strop spray. It seems to eat metal to no end making maintenance a breeze. Low carbide steels like White I, 52100 respond so quickly, and even high carbide steels like CPM-M4 or CPM-S30 respond well. With such a high level of success I want to expand my selection of stropping compounds for both edge maintenance and convexing. I ended up buying a 3u DMT strop paste and trying it out on a balsa Strop. However I really don't like the fact that the DMT pastes are oil based. To me it seems to decrease the effectiveness of the diamonds and it is just plain messy! Trying to clean up after using the Strop is a pain. At this point I'm looking to find some higher grit(lower micron) stropping sprays or pastes that are not oil based.
I am looking as Ken's 4.5 micron CBN paste but don't know if it is an oil base or what? Can anyone here help me clarify?

It's water based.

I've used it on many substrates and even on stones with no adverse effect.

I love the 4µ (now replaced with 4.5). It's a great compound.

Thanks so much Michiel. I am going to give it a go then! Post back her when I get some experience with it.

This micron size is rather interesting in that I have 3 formulations for this - the oil based suspension, a water based suspension and a water based slurry. Now why would I do that?

Well the oil based preparation is ideal for belt sanders and other powered applications because it sticks best under power, especially on leather.

The slurry is a deionized water preparation. While a simple shaking will do, it does settle rather quickly, so you should use it right after shaking. I use a slurry formulation for all particles finer than the 4.5 microns because it stays suspended long enough on it's own. For larger particles like 9, 15, 30, 45 and 80 microns I use a suspension to keep the particles from settling. This is necessary or they will just drop like a rock in a pond after shaking. Unlike some faulty suspensions, these water based suspensions will keep the particles in a uniformly distributed suspension permanently. I've yet to see any settling even after a bottle has stood still for over a year!

You can also use both the slurries and suspensions - but not the pastes - on waterstones to good effect. For the coarsest sized particles I would also recommend using them on waterstones as the base. The stones hold the larger particles in place even nicer than other bases like leather or balsa and act in concert with the stones to make them more aggressive - especially for highly abrasion resistant steels like the newer 'Richmond' series of knives. Roughly match the stone grit to the particle size for a 'balanced ' effect or use a much smaller CBN particle for a different effect where the predominant effect is on the stone and only indirectly on the steel.
