An oldish, all-steel saw blade. Clearly made of a nice steel, judging by how a file has trouble shaping it, and how it leaves scratches in drill bits. But too bad, it's made for a wacky arbor size and even if it were 5/8" I would never put it in my table saw because it is outgunned by today's carbide saw blades obviously.
I had already ground the tips off the blade for easy handling before I took this pic.
Mounted in a vise with a piece of scrap wood to serve as a straight edge.
I took light passes with the grinder to avoid bluing the tool and drawing its temper.
Finished with the first cut. I was happy with how I didn't seem to overheat the metal at all, but now I suspect the teeth are hardened to a much greater extent than the body of the sawblade. Well, this would make sense, I guess, but disappointing.
I think I might want to heat treat the steel after I cut out the blanks now.
Made another cut and deburred the edges with a mill file.
Yes, I realize I need a workbench.
That's all I did tonight.
Anyways, this is where Anon [potentially] has a role to play in the finished product.
I laid out the two pieces I will soon grind on a 1" grid. MSpaint how I should cut the knife blanks.

he makes it out of wood, but the idea is the same.

When you say light passes, do you mean you kinda cut through the length of the blade but a millimetre at the time? Or grind the full depth but slowly?

Gotta go fast

how many cutting discs did that cost?

Only 1. It isn't an emery disc. I used a left over disc to start and the final disc wasn't used much. It is all about the angle. If you get the angle right it will last a long time, but the wrong angle will chew it up very quickly as in 30 seconds.
Dremel has never been good. It has always been shit. It is merely much shittier now.

The first one.
I took light and fast passes, zipping the wheel across the blade taking off maybe 0.5mm at a time. This kept the blade cool to the touch. Keeping a cutting wheel in contact with the metal creates intense heat.

I use a wet wheel for mine and a stream of water. It is easy to diy with a fountain pump or garden hose attachment for a sink facet.

Very nice work, but I wonder why you used a blade with carbide inserts? They don't use cutter-grade steel on those, because none of the steel is doing any actual cutting.

It actually doesn't matter. The steel is good enough that it holds an edge for a long time even with regular use.
