So, I'm getting a 0560BW, and I want to get the newest generation with the steel lock bar insert. at what serial number did this version start. Also, have the problems with ZT's ELMAX been solved? I have also heard about problems with 0560s having a very weak detent, has this been a issue with newer models of this knife? I live in Canada so it is illegal for me to have a knife that can be opened by gravity so the detent is important to me. Any other changes that have been made to the newest version of the 0560 that I may not have seen on previous reviews of older models without the lock bar insert that I should know about? Thanks in advance.
