Did Jason Vorhes Ever Weld a Chain Saw?

Jason x: As far as i know, jason has never wielded a chain saw. The closest he ever gets is, i believe, in friday the thirteenth, part seven,. And so that one's a quite funny and a lot of fun. In that one, he does use a power saw, but it is not a chainsaw. It is a motor driven hedge trimmer with a circular saw at the end of a long pole. He sticks it right into terry keiser's abdomen. That was wy the face was thaying, and he should back off? I believe this is a point a few people are confused on.
