Vintage Straight Razor w/tang marked; COLUMBIA CUTLERY CO. WORCESTER MASS 10. Blade marked:  EXTRA HOLLOW GROUND FULLY WARRANTED.  Scales are pure black and shiny NO problems.  Blade has some light dark spots but overall very clean and makes for a nice display with the nicely etched wording.  Picked up my collection of razors going to many a estate/auction sales here in the Midwest and liked to buy and clean them a bit as they look much better IMO.  Would be a nice addition to that collection unless ya have a better one.
