Reciprocating Saw handle

I was surprised to see how expensive handsaws were at the hardware store. Getting a quality reciprocating saw blade was a quarter the cost and there were more options to different styles of teeth in the selection. I came up with this handle that has the cavity inisde the handle fitted to match the held end of the blade. Most 1/2 in long woodscrews will work to fix the blade in place and they thread into the plastic. No support needed for the print
