The SOG Vulcan is a very solid pocket knife, made in Japan. The popular Japanese VG10 steel was used for the blade. Of course razor-sharp! You open the blade with the double-sided thumb stud, or with the flipper. When opened the blade is locked by a ARC lock, which looks a lot like Benchmade's Axis lock. The deep-carry pocket clip ensures that you can discretely carry this knife in your pocket.
