Wears out pretty fast
Virtually all of my work is with agates. These blades only get about 2-3 slices of a 1" by 1.5" rock and then the blade is dull. Then you use the carbide stick to sharpen it - but, the carbide stick is like butter on the blade no matter how slow you push it through. It would be pretty easy to use up an entire carbide stick in one day. I don't 'force' the rock through the blade so as to not put extra wear on the motor, thus it takes a long time to just cut one rock.
