His listings of "hot saws" are just stock saws with different bar chain and sprocket. Maybe spikes as well. Maybe when he did not have one he made the price super high like some do which is against the rules but rules do not seem to mean a lot pertaining to that sort of thing. Some of his statements seem contrary to actual fact, or fact according to Stihl. Especially pertaining to the max length bar for a specific powerhead and/or chain type. But the milling guys seem to go longer than factory spec as well at least pertaining to the chain. He sells rope or line climbing hardware. I have bought some picco chain from him. I did not like his splice but he sent me parts to re do. Lately I got an Oregon drive sprocket, no problem was genuine, I would buy a 25 foot section of Stihl chain from him if I needed or wanted. I do not use that type of rope or line can not comment on that product. He seems to be a seller of Cannon bars.
