I own a 6mm (ca. 1/4'') C.I. Fall Mortise Chisel, wich i bought in Eskilstuna, Sweden, from Anders Fall past summer.

It's quite rough, but I'm not sure if that's their standard quality, because they were out of stock when i was in Esikilstuna. I did not work a lot with it so i can't tell you much about resharpening ...

But i love the modern Auger bits i bought from Anders Fall. (They're cheap, too.)

Cheers Pedder
