Just by opening this knife, you’ll know how it got its name. The Quake is one of our coolest folding knives that’s powered by our SAT 2 (SOG Assisted Technology) that propels the blade open with just a push of a thumb. Instead of a thumb stud, the cross guard folds in when closing the knife and is used as the lever to assist with the opening motion. Combined with a thick dual-tone VG-10 (this prototype is S30V) blade, Micarta handle, full length stainless steel liners, the Quake is one formidable knife that packs a punch. Rarity Note: This prototype is especially rare due to never making production and a very limited amount are known to exist.
