Yeah tapers from about 5mm at the toe to 1.5mm at the end of the tang. Not really precise since I just ground the taper in by hand since I don't have a surface grinder but good enough. I'd like to start forging razors instead of stock removal, would be much better for these style of blades and even putting rough bevel faces into razors would save time grinding but I just don't have the room atm.
