Hello got a Timberline Chameleon D/A kit knife, my buddy bought the kit put it together said he couldn't get it to open right he paid $40.00 for the kit ,if you push the hidden button really hard spring will fire,I just locked it back up ,selling as a fix it project,worst case you get a good liner lock,but for sure it has a hidden button and a leaf spring, also comes with original parts, asking $50.00 YOU CAN HAVE A EDC CHAMELEON FOR PRATICALLY NOTHING shipped sales to the U.S. only pay pal fine .
