Review on Durable and Efficient: SE 3 ⚙️ Piece Diamond Sharpening Bench for Precision Sharpening by Timothy Cole

I've never used diamond whetstones, I bought it for an experiment. They work better than expected. After using them for decoration along with water stones, I found them very useful. So good, in fact, that I intend to buy larger, longer versions for some really serious sharpening, along with the "grip" required to keep them level and in place. Revain's low price is worth it if you've never tried these "blocks" before and are interested in their usefulness.
