Review: Does the job and lasts. - This is an excellent knife sharpener. Fine side good for metal removal, very fine side for a sharp edge. Does not wear out
Review: Good kit - I have several dmt diamond sharping stones and use them regularly being as I'm a carpenter. I also use them to sharpen gardening tools and my kitchen knives. I have tried other brands because they are cheaper but ended up having to buy dmt to replace them. This doubled sided stone is great for getting a really keen edge after using the coarser grades, with the bonus of the continuous diamond to sharpen small stuff. The other bonus was this was about half price so quids in.

### ⭐⭐⭐⭐ Effective
*by F***N on 28 May 2024*

Relatively easy to use for an amateur, but no magic solution for sharpening fabric scissors - although I am accustomed to using a scythe stone and a steel for knives, neither was appropriate for scissors, which is why I bought this. Hopefully I’ll become more expert with the aid of YouTube videos… I certainly feel that this will be durable and still useful next time I take it out of my tool bag. It has a good integral cover to protect it from the other idiots in my household who might want to take it out and leave it in the rain!!!
