Topic tags/keywords: question scraper

What are your thoughts on turning a dry wall putty knife into a card scraper? I’m sure it won’t be awesome quality or what not but think it would work to get by for now?

too thin. doubt it would work too well, even though a card scraper is thin – it still has enough thickness that you can put an cutting edge on it (the burr).

card scrapers are not expensive, don’t think there’s any reason to cheap out and ‘get by’ with anything else.

:) well, in that case – it’s worth the try.

flatten and hone the edges, and see if you can either use them as is, or put a burr on it – I’d be curious to see how well it works. depending on the thickness of the knife blade this may or may not work.

some folks are using glass plates as scrapers (cut offs, scraps).

I’ve been making my own card scrapers from used hand-saw blades, particularly modern Japanese pull saws.
I take the blades to a local metal shop that chops them up to the sizes I want.
I true and dress the edges by draw filing, then I turn a burr.

If you can turn a burr on a putty knife, then it might work. Try it.

I was introduced to card scrapers about 40 years ago.

try running thru some manufacturing areas and look for metal dumpsters, find a nice thick small chunk of sheet metal and sharpen that, not as good as the spring steel normally but its cheap, the wife wont mind that so much ;)

Cut an old 7 1/4” saw blade in half, just past the hole, square the ends, remove the teeth and smooth to make a curved back. You can then square the base, polish, burnish and roll the burr. You can also make a curved scraper on the curved edge. Easy and cheap. Tell Momma you spent $7 for a scraper and go buy a six pack.
