"The TomCat 3.0 will win a place in your hand. Like a modern day tank this heavy duty folder is big time armament but has the finesse to turn on a dime. The TomCat 3.0 features Arc-Lock that combines speed and safety in controlling the big 3.75-inch blade. Surprisingly light for its size the TomCat 3.0 is also quick and smooth to deploy with either hand using the double thumb studs. The VG-10 blade rotates effortlessly to lock up in SOG's Arc-Lock. Tested at over 1000 lbs. of force at the lock the Arc-Lock is SOG's strongest lock. The handle is made of stainless steel and textured Kraton which make it lightweight and easy to hold.
