I am a hobby carpenter, but I make beautiful furniture. I have a very good jet slotter. I bought a set of 4 grizzly bits and used them. I decided to buy a much nicer chisel to build my new workbench. This thing is unlikely to be cut. I have tried and sharpened many different drill bit positions. I had to use a demolition hammer to get the chisel out of the wood (soft maple). I pulled it out and decided to try my old rusty set of grizzly chisels. 4 chisels for this price. And this is not a high quality Japanese set of a grizzly. The cheap grizzly chisel cuts through soft maple like a hot knife through butter compared to this piece of junk. I hate this so much this is the first review I have ever done. Save money and buy something else.
