Description

I’ve been asked a lot about my sharpening stones. Some people just want to “try it out” before committing to a full set. Because of popular demand, I am proud to offer this single stone for sale: consider it a trial entry into the world of high performance resin stones. You can check whether you like the feel, the performance and the sharpness created.

1 (one) sharpening stone with 30 µm diamond.

Size of the Aluminium Blank: 159 x 25 mm x 3 mm

Size of the Abrasive Layer: 150×25 mm + At least 4 mm thickness

Diamond Concentration: >50% by weight!

Factory Dressed via contamination free single point diamond chiselling.

Comes in a 3D printed storage box.

These are the “Dr. Marv’s Scientific Sharpening Stones”. They have an unheard of concentration and are absurdly pure and contamination free. This was achieved by very tight, electron microscopy quality control, followed by manufacturing in a laminar flow box. Dressing is done via single point diamond chiseling, which also stops any contamination. Moreover, every set is diamond chiseled individually in the same fixture, so the stones are very, very close in their thickness. I personally do not feel the need to adjust the angle when switching from one stone to the next.

Their development is based on my scientific research into abrasives. I firmly believe that these are super high performing abrasives!

I am very proud to say that the resin, filament, foam, chemicals and aluminium are Made in Germany. Machining of the aluminium blanks was done in Germany. Only the diamond is imported, but meticulously quality controlled via SEM. I am absurdly proud to state that all abrasive stones are handmade by me in the German Alps. As this is a handmade product, some small blemishes such as tiny bubbles, scratches or imperfections are to be expected. I can promise that they do not subtract from the performance of the sharpening stones!
