Leather shops working knife

Here comes straight out of my workshop a new leather knife "3 in 1" that allows as well to trim it, to dethicken and cut the edge at an angle, shape of the blade designed not to have a gene of the handle! Carbon steel (sheffield origin, connoisseurs will appreciate), oil quenching, French walnut wafers mounted with copper saddle rivets. Handmade artisanal production! Watch out for your fingers!
Length 160 mm, cutting 30 mm!
Use on cutting mats, oil stone sharpening, sandpaper 600 or 800 grains, sharpening leather finish shops
