🔪 Durable Professional Diamond Whetstone Sharpener: Premium Abrasive & Finishing Kit Review

Bricks No. 800 and #1000 were marked incorrectly. They have been turned. Stone #1000 was rougher than stone #800. I contacted the seller (with photos) who said they would send corrected replacements. More than a month later and no replacement, no contact with seller. UPDATE 11/15/21 I finally got a replacement so I'm going to upvote it to a 4.

Perfectly good stones! They are true to size and generally fit as advertised. Some of these had large "bumps" embedded in the stone's surface, making them far less useful. I have to be very careful to stay off these bumps or I risk tearing a large chunk of my well-deserved sanded edges. I end up just skipping this grits. It was only two stones and the package is full of sand to go around them. I use them wet with water which seems to keep the stones clean and easy to cut.

These stones are reasonably priced and seem acceptable at first glance. What I noticed when breaking the stones is that the numbers are written in a different script and the 1000 stone is just as coarse as the 200 stone, the 400 and 800 are the same grit while the 500 is better than the two. I think someone just took 6 bricks out of the bucket they fell into from the conveyor and randomly labeled them, or maybe they're defective bricks that didn't pass quality control for a more accurate set…
