This razor is a dark horse, as we cannot make out all the markings on the tang, we can identify I-xl and 'Sheffield', so it is in all likeliness a GEO Wostenholm & son blade. GEO Wostenholm & son is quite a well known brand of razor, and they are well known for the good quality razors they produced, to this day they remain some of the most popular vintage brands that are always in demand. The company operated from Rockingham Works 1809(1815) - 1848 and from their Washington works from 1848-1978
This tatty ratty offers a vintage Sheffield blade as its primary value, it has charcoal 3D printed scales that means no worries about fancy scale materials deteriorating over time.
This rat is real, abuse it, its gonna come right back at you every time!
