A while back, Dom of Two Guys in a Garage (TGIAG) sent me a couple of prototype steel folded backs for my review, which can be seen at this link:
They were good - not perfect, but good. I did end up making a couple saws from the backs they sent:
Well, good news for all of you do-it-yourselfers out there who have been itching to make your own saw, but have backed away because bending or slotting a back was beyond what you wanted to do ... They have just made folded backs available for purchase on their web site.
Not only that - but what they are selling is substantially improved from what they sent me. The profile they are bending is more like the classic profile used during the golden era of hand saws, if not identical to it. And - available in both brass and steel.
They also have split nuts and pre-toothed saw plates available. All reasonably priced besides! I recommend these guys completely.
