My understanding is ‘back in the day’ the old timers used to make their own scrapers from old saw blades. I’l like to try this myself using one of my old hand saws. Does anyone have any comments on how to saw a sawblade? Not sure if a hacksaw will cut a sawblade, seems like they’d both be the same hardness, any ideas or does anyone know how the old timers used to cut these out?
Thanks,
Jumpman

You might try tin snips -- the heavy-duty type used for sheet metal and ducting work.

try buying a very fine metal cut-off wheel(1/16thick approx)
for your bench grinder.
I use them for rough cutting shaper steel for grinding my own molding
cutters. If you don't own a bench grinder you can also use a hand grinder I keep one set up with a metal cut-off wheel and one set-up with a sanding wheel.
Hope this helps

You can buy a (round) carbide blade to fit your hacksaw--it will even cut ceramic tile and glass--not all that expensive either. Just a thought.
I hadn't thought of a particle cutoff wheel for the grinder/saw. Do you suppose the heat from the cut would would destroy the temper of the steel at the edge, ruining the steel for holding a sharp edge? Might just have to give it a try just to see what happens...
Thanks everyone.

you can also use a little cut-off wheel in a dremel. no need to cut all the way through. just score a pretty good line, maybe half the thickness of the blade, and bend it. the blade will snap. then just dress the edge.
bruce, who has a bunch of scrapers donated by an old handsaw blade.
Any good bimetal hacksaw blade will cut them. Saw blades are not that hard (since files will cut them). I use Lenox bimetal blades.
Jumpman, I used the edge of a trangular file to score the saw blade and then snapped off the scraper at the scored line. It works suprisingly well. Just score the saw blade well before mounting in a vice.
