Wiss Special Imitation Ivory Oval Silver Tipped 464
This is not in any catalog. This has the Wiss logo stamped on the tang, making it after the c1912 catalog. No catalog lists the 464 on the tang. The blade is a Sure Grip. The 400 series appears to be from a Sure Grip series with an alternate blade shape. Or the numbers used with a name etched on the blade. This item passed through eBay in May 2011.
