OAL about 8-1/2". Blade marked 440 Stainless below that is R.O.C. I believe this to be made in Taiwan. It is definitely not made in China. When button is pressed double edge partial serrations on both sides. Blade springs to attention. With a hard hitting sound as it locks in place. With a tight lock up for one of these types of knifes. To close knife push button back in and manually recock with the side lever on blade. Let go of button before pulling the blade back into place. This knife is extremely strong sprung and locks into place every time the button is pushed. I have owned this knife for well over 10 years. Works as it should. Quality made.
