Review on Utoolmart Chamfer Cutting Chamfering Woodworking by Adam Matthews

How do I send a knife that has not been sharpened and has obvious signs of corrosion? This is a dangerous piece and if someone tries to use it they could get hurt as it doesn't chop the tree it destroys it. The thing is designed for strong recoil. I'm going to send it back, but it has to go in the bin.
