That's the same knife. That 4.75-inch model was released as a Mini-Sus Scrofa (Sus Scrofa is Latin for wild boar) [See
The Busse Collector site]. I'm not aware of any full sickle sized/shaped Busses out there, but who knows what the future holds. The thickness of coated versions was listed as 0.187, satin versions list their thickness as 0.170.
