First of all you should all buy this bit as it is made in Austria NOT China. This is a quality hit! It gets razor sharp (and stays that way for a long time), which explains the title. If he rolls off the bench, DO NOT try to catch him. I know, I know, when a $20+ club hits the floor your first instinct is to catch it. Believe me, no, this "fish" is more like a shark and will take a piece away from you! I use it on my lathe, hand drill and drill press. I usually use it on hardwoods like purpleheart which has a janke hardness of around 2500 (for reference, pine is around 400). My cheap Chinese beats smoked and burned, not these! Cuts like cheap, oil rubbed, overheated chinaware. Or a razor-sharp duck that falls onto soft skin and gets caught.
