Query: Wire Foam Cutter

This product is useless for cutting larger/thicker sizes of foam.The wire cuts very slowly since its so thin and the bow design canlimit what type of cut you can do. So I bought a HOT KNIFE which easilyplunges thru foam and makes a quick job of hollowing it out.Spend the extra money and get HOT KNIFE instead!
