Knife specially designed for fur work (approx. 10-15 cm long), completely made of metal and without handle, often with two copper beads, one on the high back and one on the flared end. The index finger then rests on the bulge on the back; the palm of the hand rests on the bulge on the end of the knife.
There is also a model with an interchangeable blade and a model in pocket knife format (fur knife + small furrier's comb).
When cutting, the fur is lifted with the left hand so far that the cut comes clear of the table; so the hair is not cut. [MOT]
