Picked up this "Tiger" straight today. I have heard the name and there are a number of Gentlemen on the forum that have this brand. I would like to get some information as to the manufacturer (Sheffield, Dovo) ??? that made these razors. It appears to be pretty old I'd guess around 1920's (?) It was in pretty rough shape when I got it from the Antique Store and the edge was good but very dull. I didn't think I'd be able to get a good edge on it but with some cleanup and honing and stropping it took a VERY keen edge. This thing is sharper than my double hollow grinds! Does anyone have any info???? Thanks!
