Antique I Wilson butchers knife made in Sheffield England in the mid to late 20th century. I Wilson was in operation for a long period of time (1750-1970) but was especially a huge producer of butcher knives in the 19th and early 20th century, the bulk of which were exported to the USA. Most I Wilson knives found by us here in the USA are hand forged carbon steel with a 3/4 tang and simple pinned beechwood handle. These were made to be inexpensive but with a good quality steel and gave domestic producers in the USA a run for their money. 

This knife is much more like knives from Sheffield we have found made in the mid to late 20th century with its non-tapering tang and steel pinned rosewood handle. This pattern is nearly identical to some old stock A Wright knives that were found as old stock in the 1990's, assuming they were made in 50's to 70s.

This knife has been re-ground and thinned behind the edge a little, it comes with a fresh edge.
