The fixed Blade Vulcan was discontinued a couple of years ago. It has a blade design that people seem to either love or hate, but I think
there is at least one or two reviews on youtube. The blade is sold VG10 and the handle is the same highly ergonomically comfortable design as the folders. About the biggest drawback that is often said about it is that SOG packaged it with a leather sheath rather than a
kydex one, which with more suited to it's "tactical" styling. Yes, there are nicer SOG fixed blades. I know because I own most of them.
The Vulcan folders, as well as all the other Seki made SOG folders are manufactured by G.Sakai, the same company that made the knives for Al Mar and Spyderco until they switched to Moki a few years back. The quality of these folders are top notch, and really remarkable that SOG continued to have thes made in Seki Japan, even though they switched nearly all of their fixed blades to Taiwan
production. In order to continue making them in Seki despite the high Yen exchange rate over the last 10 years, SOG had to cut corners where it could. That explains the GRN handles which usually draws a negative comment from those use to to G10 scales. These Seki SOGs are also overlooked because so many people have had unsatisfactory experiences with SOG's lower priced folders and believe (and spread the misimpression) that all SOG folders are bad.
