Howdy,

Those appear to be braze-in inserts. A slot is cut in a steel bar and the insert is brazed in generally using bronze foil, then it is sharpened with silicon carbide and diamond grinding wheels.
They might be good for roughing scaly steels.

Enjoy,

OK

Hey Guys,

How are these used (see photo)? Do they need to be sharpened? Is there a specific holder for them? Any use for my SB9c?

Thanks,

Greg
