I was going to bid but the auction got carried away by 2 bidders. Looks like a 1700s razor, but the blade is 1.5" wide at the end? eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

Never seen anything like this one. Is it just me or do the tortoise scales look pretty new for how old they would be? Thoughts on how old this thing is?
