I have recently bought an old Stanlet No 12 scraper pland that is in excellent condition. The blade is a replacement, but everything else appears to be original, no cracks or damages.
Question about sharpening the blade. Given that a card/cabinet scraper blade is sharpened square (ignoring the burr) why is a scraper plane blade sharpened at an angle?

I thought my 112 was honed square, but nope...filed at a 45. It works great, so that's reason enough for me! Maybe next time I'll file it square just to try it. My guess is that it works better through the full range of adjustment available through the blade holder mechanism than it would if square.
Good info on your #12:

I read that info a couple of times, very interesting and informative . Here is mine ...
Cabinet scrapers often have 45 degree bevel. At least one very good sharpening resource (I think it was the book “making and mastering hand planes” by David finck) recommends just making cabinet scrapers blades square.
I believe the rationale for an angled bevel is so that you can more easily get that the work hardened edge to be at an obtuse angle relative to the front of the blade rather than acute.
