New to posting generally, new member. I've read through the articles on canted saws and there is an aspect not covered as far as I can see. Done many years as a professional tool restorer with a special interest in saws. I found that refitting the back to the blade frequently results in a wobbly edge which I learned to cure by tensioning the cutting edge of the blade, top front of back vertical on bench, striking firmly down on front teeth with nylon mallet. This has the effect of pulling on the toothed edge, the back holds most of the blade length and the blade is driven slightly into the front end into the back, instant cure, usually. I discovered this myself but it occurs that it may have been common practice in the trade with the end result that blades are repeatedly driven in at the front whenever it looses tension for whatever reason. I realise that this doesn't impact on the early canted illustrations but it would explain why 95 % of used blades are canted, mostly all the way in.
