Fast-cutting diamond stones for controlled sharpening of modern steels, super steels, and ceramic knives.
Cutting
Diamond abrasive provides aggressive and efficient steel removal while keeping a consistent sharpening speed as fresh diamond particles are exposed during use.
Feedback
The metal-organic bond gives the stones high wear resistance while keeping the sharpening feel smoother and more comfortable than a typical hard metal bond.
Maintenance
The stones do not require soaking or complicated preparation. The surface can be cleaned with a Hapstone Dressing Stone to remove metal particles and restore cutting performance.
Application
Hapstone Premium Diamond stones are suitable for knives made from almost any steel and are especially effective on modern super steels and ceramic knives.
The black anodized aircraft-grade aluminum blank provides rigidity and durability during sharpening.
Durability
The high diamond concentration and durable bond give Hapstone Premium Diamond stones a significantly longer lifespan than traditional water stones.
Finishing
For the final polishing stage, Hapstone diamond suspension is recommended after sharpening with diamond stones.

Great product! I already owned the premium CBN stones 50, 80, 150, 400 and 800 grit which I love, but I wanted to see how the premium diamond would perform. The premium diamond is a bit more aggressive compared with the CBN, I bought the 50, 120, 240 and 600 grit. I sharpened already a big variety of steels with the stones.. cpm 15V, Maxamet, Cpm Magnacut, Cpm Cru-Wear, K390 etc. Even with the lower grit stones it's super easy to get hair whittling edges because the Hapstone system makes it so easy to de-bur. I sharpened the Spyderco endela k390 at 15 deg. at 240 grit and did the de-bur with the 600 grit and stropped with 1 micron diamond emulsion. It's even hard to do hair whittling because the knife just want to laser through the hair. I can only recommend Hapstone products.

We learning on new my TSPROF K03 Hunter sharpener. Decided to try Hapstone Diamond stones. Very nice put a nice Polished edge on a cheap D2 steel knife, and a mini Adamus knife with cru wear blade
Every purchase I've received from you guys and girls has been as advertised, on time and followed up on ensuring customer and product satisfaction. I went straight to work with the Hapstone premium diamond 600. Now, It is a smoother grit 600. Just a finer abrasive makeup. Feels like an 800 but cuts just fine. Cuts gooood. I typically stop at 800 so 400+ and 600+ are the two most important stones I use unless I'm reprofiling. Initially I do lightly lube and clean my stones more often than I would after broken in I guess. But ya I had three knives waiting for the 600 and 650 to arrive and ive been only using the Hapstone 9135 on all three blades the last couple days and Im very pleased!! Also, I've got an edge pro diamond 650 I picked up from Hapstone that I have yet to try. So we shall see on that one. Well there ya go. Thanks. Stay Sharp 🤙

I really like the stone. At first, it doesn't feel like it's working at all, but it leaves an excellent polish.

Hapstone 50, 150 Premium Diamond Used these for the past couple months to sharpen S90V, S30V, Maxamet and Magnacut. I have the Veneiv Orion, and Edge pro diamonds. I will say I am impressed with the Hapstone. Much quicker and more working material than all others. The aluminum base is much thicker than the others and perfectly straight. I highly recommend for re profiling.
Store owner replied: Thank you for your appreciation of our work and our product ! Have a great use !
Hapstone premium Diamond 50,120,200 I use these Stones to start the edge of new knifes I made that have no edge at all. The 50 grid stone is super agressive and removes material really fast. In hindsight I wasted alot of time not using a good sharpener and stone in the past. Also the 120 and 200 Diamond Stone work really fast and well, and I´m sure I can sharpen alot of knifes with these quality stones! Keep up the good work and the awesome quality Hapstone!
Store owner replied: Good day dear Mr. Johannes ! Thank you for your feedback! Great use !
