Can anyone help me identify these 4 knives. They were in a black padded suitcase and marked Prof. Slaughterhouse knives.

These are obviously well worn down knives used by a professional meat processor.

The middle wooden handled knife used to be a Russell butcher knives, and the other two seem to have started off as Russell stiff narrow boning knives.

I can't identify the black synthetic handled ones, but those 3 with the wooden handles are pretty distinctively Russell knives.
Most likely these were sharpened daily on some kind of electric sharpener for years and years to wear them down like this.
