attempt at making trade points from a skill saw blade
Robo:
Cutting with a plasma cutter or torch will burn the carbon out of the steel. Annealing the metal first will make it much easier to cut and grind. Retemper and resharpen the points when made.

I tried the dremel cutting wheels and they worked ok exept they break real easy.

The reinforced Dremel wheels last much longer and I've not had one break on me yet. I use them to cut out knife blanks. If you go slow enough (don't change the color of the steel) you should not need to anneal or re temper.
Also, if you can find non carbide blades they are made from better steel and will be more durable points.

look for 10" or 12" miter saw blades without slots, you can get lots of points from those! and the non carbide ones aren't very expensive even new last i looked.

Soy,
I did the miter saw thing and blades came out at 300 grns. I like everything about them but they don't sharpen well. I think the annealing is the way to go but I don't know much about it. These things go through 1/2" of plywood with no problem.
