## Customer Reviews

### ⭐⭐⭐⭐⭐ Small it so useful
*by  on Reviewed in the United Kingdom 14 December 2019*

I use it as an essential part of my sharpening equipment for my woodturning chisels.

### ⭐⭐⭐⭐ Not the advertised/named length
*by  on Reviewed in the United Kingdom 28 January 2026*

This is sold as a 4 inch whetstone. It's actual length is 4.4", worth noting if you need to mount this in anything that requires a specific length. Otherwise this is very good.

### ⭐⭐⭐⭐⭐ Excellent quality sharpener
*by  on Reviewed in the United States 23 November 2012*

I bought this coarse stone along with some of the other DMT stones awhile ago and have become a huge fan. This particular stone is very effective at repairing an edge, but what I'm most impressed with is the quality. The construction of the stone is solid and tolerances are excellent. This truly will be a lifetime tool for me - which is an important consideration when I buy tools. It's a great example of a quality product made in the USA.
