My 561 has no lockbar insert nor do I want one. One more thing to fall off and lose screws. Looks-wise, cmon..... And I believe it unecessary for most owners.
btw, there's something about the 561 being superior to the 560 in the area where the lockbar contacts the blade; something about the lockbar/blade interface I think. I think it has something to do with a slightly longer or thicker area of support on the 561 lockbar ?? Anyone else familiar with that technicality or heard of that? I've seen it discussed here......
OP--The 561 you receive will be fine...one of the best knives ZT ever made. It's very unlikely you'll wear it out. There's a break in period with this ZT. Any lockstick you experience will go away. I can only tell you I have the 60 and 61 and both arrived and are to this day FLAWLESS. Prior to that I was down on ZT's, too.
