>>8682438A couple more chinese chisels to review.
First one is 0.4mm. The width is right on the money this time.
I don't have a 0.4mm BMC so I used a Funtec chisel for comparison instead.
The scribed line looks nearly the same.
I didn't try to remove material with it seeing how the chisel is held in place by a bit of hot glue and the handle is hollow.
