I remember either an article or a video of a very large chisel-appearing tool.  Maybe 2 feet long. Wide – maybe 4 to 6 inches, or better. It might have been concave-curved. I don’t think the article was about just that tool, and not about tools in general, but I’m an old fart and shaky on the memory thing.
Been awhile – years; possibly decades.  Might have been used for log construction, maybe shipwright, maybe for bark-removal from logs.  My search skills on FW site are obviously deficient, if it’s here.
My thought was to use it for, among other things, bark removal where a spoke shave isn’t big enough or appropriate.  If a common sidewalk ice-scrapper was sturdy enough, that would do it for a larger size.  I’m not a blacksmith, so I’m not making my own.  If it comes in sizes, a 2 footer and a five footer (as in long-handled) would work for me.  I’d settle for 18 inches.
Anyone got a link or an idea?  Or a clue for the clueless?
