Oooweee, sharp, works like a dream when attached to my grinder (be very careful). I've been using it very, very heavily on a crazy 8" log greenhouse and it hasn't dulled a bit. Check out the pics
Its still amazing and using it is the most fun ive had in my adult life, just be careful!
I'd like to start off by saying this thing is amazing and don't be fooled by the price. If you plan on doing any kind of carving I would absolutely recommend this. It will save you so much time and you'll find other things that you probably want to attack.
Fast cutting tool. Get a really firm grip on your grinder because if this catches a bit the recoil could make you loose control of the thing.
