Stanley Blade Holder was made by Stanley from 1936-1942.  I not sure of the exact date this one was made.  This is a number 198.  The holder measures 5" long and is made of Japenese cast iron.  It is used to hold razor-type and spoke shave cutters for honing.  This one is in good shape.  Please examine the photos carefully and closely.  The photos clearly show the cosmetic condition of the item.
