do those, perhaps, take advantage of unintended transformations?
Hmm... I couldn't tell what transformation was intentional and what wasn't.
E.g. hammering a Heated Beta Blade intentionally transforms it into a cold Delta Blade, but is the transformation of a Super-Heated Brittle Blade to cold Stock on the anvil intentional or not?
Oh... and
whose intentions are we talking about, anyway?
(BTW I made a full list of all transformations that you can do on Forge, Anvil, Quench Tank, and Sharpening Stone. So I could help to verify that the actual transformations meet the intentions if there's interest - I have a background as a professional software developer and tester, so I know how to make such feedback complete and reliable.)
