Old butcher best Knife with blade marked Blue Diamond, L.F. & C., Double Shear Steel, Butcher's Pride, and a word that looks like "Junwerson" or "Junwersom", I can't make it out completely. Handle has impressed with a mark of H. A. McGinnis Co. 37 So. Front St. Philadelphia. Blade needs some cleaning, has lots of dark spots and light rust in areas. Should clean up though.
