Phil Wilson uses one and has used one for quite a while.I have a brother that has one and uses it quite a bit with his business.The folks I have talked to that use them really love them,but I sure would not want to have to breathe that stuff,either.Where I work they have several of them but I have never seen them work.One of the millwrights told me they no longer have anyone working there that knows how to run them!Thats gov't. $ working for you! O'l Phil Wilson is a great knifemaker and a hell of a good guy.If you talk to him he would be more than glad to inform you about plasma cutters.He is a maker and knife writer for KNIVES ILLUSTRATED.O'l Phil is one of our Calif.makers.I lost Phil's phone number,but I beleive you can contact him through KI. Phil is a pioneer of S30V,used to have to buy it in BIG slabs,so he bought the plasma cutter and used it quite a bit. Good luck,guy.
