Christopher H.wrote a review of SOG Knives Twitch XL Knife on May 22, 2009
initially I liked this knife a lot. I got it to replace a CRKT I lost and liked that it had the heel-flip open. the spring was quick and solid and and the action smooth. blade was wicked sharp, and I liked the reversed clip that made it a little bit easier to pull from your pocket. overall I was really impressed.
then the belt clip broke off, after maybe owning this knife for about 3 weeks. it always felt a little tight so maybe it was too much stress to have it pulled on all the time. I'll be sending this one back. also i really did not like the lock release on the back of the knife. It made it basically impossible to close with one hand which is a huge drawback. if you don't mind that, and yours doesn't break, it'll probably be a great knife.
