   Kent,

   Well, now you have a passel of dull saw blades you can use for scratch stock blades dontcha? ;-)

   the toothed side will be real hard, so can be shaped pretty much only by grinding, will be hard to get a file to touch that edge, but the backs are generally soft enough to easily shape, and will stay sharp long enough to work for you, unless you are scratching miles of moldings.

   As far as your scraper, you could score it by grinding a groove, then snap it off, and clean up with grinder/files.

   Two sources are available

   Hock Tools and Lee Valley both have scratch stock blanks available on their websites.  You can also cut down handsaws or card scrapers with a hacksaw to make blanks.  I prefer to use my scroll saw with a metal cutting blade to do this.  I sandwich the metal between two pieces of 3/4" plywood scrapes to keep it from flexing while the cuts are made.

   Blanks

   An old hand saw blade will supply you a long time.  Try heating the blank to soften it - grind the profile - than re- harden the steel -

   You can pretty easily cut up metal with a dremel and the abrassive blades they sell.  The wear quickly and are fragile, but a fresh one spinning will cut quite substantial metals.  I got turned onto it by a pal who was building chopper frames, and cut out the 3/16" tubing with a dremel.  I thought he was nuts, but while not a serious production technique, it really does cut metal well.  Of course the same goes for blades for a 4" grinder, and on up.  Sounds like you stock is too hard, and one has to consider whether it is safe the a 90 degree scraping operation with a big handle attatched it.  I'd do it, but I woud probably be looking for something else.

   Also, you can sometimes just score the metal about 1/2 way then snap it.  All the normal precautions should be taken, eyewear, wrap it, etc...  This reduces the wear on the dremel blades, and makes it less likely you will get a catch and have little bits of blade flyiing every which way.

   Cutting scratch stock blanks?

   I have had an easy time cutting old saw blades to size simply using "tin snips".  Round chain saw files make short work of shaping too.

   Thank you Garret Hack and FW for your fine scratch stock video!

   Buy the scratch stock blanks from Lie-Nielsen.  They're made of annealed steel (not hardened yet).  You can harden them after you file your profile into the blade.  Or not.  Up to you.

   This is easy.

   Get a composite blade for your chop saw or table saw. These will cut anything up to and including high speed steel, and it is inexpensive. You might want to make a little wooden jig to securely hold it, especially if cutting on the tablesaw. When cutting you also want to blow through it as fast as possible so as to not generate excessive heat.

   Or... Don't cut it at all, you can grind multiple profiles on the 4 sides of a scraper and use it as is.

   scratch stock scrapers

   I like to use feeler gauge stock.A 1' length can be purchased for a $1 or 2,it cuts and grinds and files easily. Diffrent thicknesses in .001 increments can fine tune your scraping technique. If you use a lot, 20' rolls can be had for $25 or so, last you several lifetimes. I suspect it can be hardened and tempere as well, though I have not tried it yet.

    Scratch Stock Blanks

    Hope this isn't too late but here's the best I've found.  Jorgensen makes a hand miter saw (#64009) and the replacement blades are about 1 1/2" wide by 18" long.  They can be cut with a tin snip which will leave a slight bevel but that is easy enough to flatten out.  I teach a class on scratch stocks and these work well.  Learned this accidently when I was too cheap to throw used blades away and tried them out.  I also use a grinder to remove the hardened teeth.

    Here's a picture of one, pretty easy to file with chain saw files for curves, triangular for others.
