Ive bought 2 of these at walmart and could never find them again until i checked amazon this knife is the best knife ive ever had just give it a little tlc and you got your self a great edc dont listen to whimps that can disengage the lock workout bro not the knifes fault also if you loosen the main screw just a little and put some wd40 or oil on it it opens like a spring assisted knife which is great for me because i dont like spring assisted knives for legal purposes is the right size not too big not too small
