If you would like to cut hard materials, there is no reason to choose diamond knives every time. As you might know, the edge of a diamond is very sharp but fragile because of its sharpness. Some people, maybe you too, refrain from using diamond knives to observe certain materials. There should be alternative methods to get good results, we have been considering.

We may solve your concerns if you have some due to the reasons above.
