The break-in varies but usually takes several uses. Your stone isn’t wearing out—it’s adjusting for long-term use! Why does my diamond stone feel aggressive at first but smoother over time?

Review: Couldn't be happier - Amazing product easy to use it has a rough side and an extra smooth side for getting your blades nice and sharp with a strong durable case with a non slip grip base and design to mount the sharper, so you get secure firm and stable sharpener with the extra safety. There is a adapter as well which sticks to both sides of the sharpening face to assist with angles to get the best edges for your blade. The device is a reasonable length so you can use it perfectly for multiple blades, I have used this to keep my work knife and my kitchens knives perfectly sharp since I purchased it... Great value for money and easy to store away in its case with little space required.
Review: Great for learning to sharpen a knife - Does a great job at sharpening knives. Probably should've bought the larger size, but it works perfectly fine for smaller knives. I wouldn't say I'm able to do it perfectly but am able to get a satisfyingly sharp knife. Good for the novices out there.

### ⭐⭐⭐⭐⭐ Really good value for money
*by M***S on 7 December 2025*

This diamond whetstone good quality, and good value for money. It seems to have good and consistent diamond size, and good bonding of the diamonds to the base. The whetstone seems to be flat, and you will have an enormous problem changing that. The base is a good weight, and the box makes a good, stable platform for the whetstone when sharpening. With care this should last a lifetime. The angle guide is of limited use. With practice you will be able to get shaving-sharp edges on most blades or tools.
