This is a very old vintage straight razor from Joseph Wostenholm & Sons, Perseverance Works - Sheffield, from between 1854 and 1867. This means the razor is between 146 and 159 years old.
The blade has professionally been restored and re-scaled. Looks super.
The scales are Tropical Yellow acrylic tapered with a faux ivory micarta wedge. This is a higher grade acrylic with superb optical clarity, excellent resisting to natural aging and heat resistance.
The blade is very clean with no rust, cracks, chips or disturbing stains.
Just a few remaining residual surface pits left around the engraving as it would have meant losing all engravingvduring the restoration. Hardly noticeable.
On the front tang it says: Joseph Wostenholm & Sons - Perseverance Works - Sheffield
Subtle smiling spine and edge, barber's notch
Near wedge to 1/8 Hollow
Total weight: 2.0 oz
Total cutting edge: 2.75 inches
