www.sog-knives.net Using the coil spring action of the SOG Assisted Technology, this SOG Twitch XL with the graphite handle is full of fun. The AUS 8 blade deploys in a hurry once the owner opens it with the thumbstuds. A reversible pocket clip with the SOG name inscribed is mounted on the handle. This SOG TWI-20 model shown here is just right, not to big or small. You’ll find yourself wanting to experiment with this knife, but remember, if you shake it more than once you’re just playing with it!
