what on earth is this?

Sorting through the sawblades that came with my latest toy and found this blade.

There is no tungston carbide, just steel. 10" blade.

Difficult from the photo but possibly a Slitting Saw (Engineering)

It's an old style pre-TCT fine cross cut blade by the looks of it. When sharp that sort of blade was sharper than any similar tungsten carbide tipped version, but the sharpness didn't last very long. In one of the first workshops I worked in there was quite a collection of similar blades, rip, cross cut and general purpose tooth patterns, everything from about 10" diameter up to something in the region of 24" or 26", and they, along with bandsaw blades, etc kept the saw doctor pretty busy, ha, ha. Slainte.

Looks to be hollow ground possibly for plywood, most certainly for smooth cuts. Jamey

Hi Mick
Looks like a saw doctor's prayer to stay in business for sharpening. :lol:
I ended up modifying a fathers into other tools, as the cost of sharpening outweighed the cost of a replacement blade

Thanks chaps. Enlightening!!

My new saw came with nice collection of blades, some with some very hefty lumps of tungsten so I should get plenty of sharpenings out of them.

Sooooo, this one should make a good coaster then

It looks like a metal cutting blade, runs at a slow speed and cuts ferrous metal.

I have one like that, bought from a neighbour (now dead) who was winding up his joinery/building business about 25 years ago . It came with a Stanley portabloe circular saw and a number of other blades, none of them TCT. I don't for minute think he would have used it for metal, so I think the poster who said it is a crosscut blade is right. I'm sure the old Stanley still works but it must be 20 years since I used it, I seem to remember it was a bit fierce, lacling the soft start electronics of modern kit.
