As a professional carpenter who has worked in commercial construction for over 30 years, Ontario-based woodworker John Heisz is no stranger to making use of old and rusty saw blades that he comes across. As a matter of fact, he has an entire YouTube channel where – among other projects – he injects new life into otherwise completely useless blades.
For his most recent project, Heisz transformed a 12″ masonry diamond-tipped circular saw blade into a two-handle straight drawknife.
“I’ve never owned one and figured I really didn’t need one, but when thinking back there are many times I could have used a draw knife – situations where I used a block plane, electric plane or belt sander to whittle down or roughly shape a piece – could have gone much faster with this tool,” says Heisz. “I’ve been asked a few times if I could build one and this project has been on my list for quite a while, so figured now that the warm weather is here again, I’d take it outdoors and get this one done.”
Starting with researching existing drawknife designs online, Heisz figured out a blueprint as to how to best approach making his own before diving in head first.
As he explains:
“Of the ones I looked at, I liked having the handles splay off on an angle, figuring this will keep my hands at the most natural position. Makes sense that if you will be using this for an extended session, it should be as comfortable as possible.”
