Hi Harold,

I followed your thread regarding diamond vs. silicon wheels. One point of
confusion. Steel should not be ground on diamond. How come the Drill
Doctor and my el-cheepo knife sharpener use diamond impregnated wheels? Is
it simply a matter of short life time and I buy a replacement wheel? Or
there alternative cutters for consumer quality products?

Thanks,
