Hi Tom,
Ah ah! I thought those pixs of yours looked familiar. I am new member SixCats! (aka HARDBALL) at Blade Forums. I recently acquired a vintage NICHOLS BROS. Lamb Splitter to go with my Circa 1920's-30's NICHOLS BROS (Greenfield MA) "Beef Splitter" which is a whopping two and a half feet in OAL!
The cutting edge is ten inches and the blade is seven inches at it's widest point (front of blade) and twelve inches diagonal. The back spine of the blade at it's thickest point is almost unreal at a HALF INCH thick! The handle (metal with wood) is eighteen inch long. The overall condition of this awesome vintage "Beef Splitter" is quite good indeed. I hope to be able to post pixs in the future.
Regards,
SixCats!
