I purchased the 5ml bottle to test and immediately ordered the 30ml bottle. The 4ųm is now my go to suspension for my high wear steels that favor toothy finishes. The 4ųm Stroppy Stuff makes short work of any remaining burr and leaves a clean apex under magnification.

Absolutely fantastic. A new must have in my sharpening routine. I have a strop on my desk loaded with .5ųm Stroppy Stuff and a coworker used it. “Wow that has bite.” I expect he’ll be making an order soon enough. Delivery was flawless as usual.

What is there to hate? There are so few diamond emulsions on the market who truly have the best diamond particles you can buy so when you find the best, you stay with them.
