If you say so. I've never seen one with any caps on it, I've never owned one that didn't have enough lock bar tension and I've never needed one to have a bigger stop pin installed. I have had a loose pocket clip replaced, broken blade replaced and personalized etching put on one (3 different occasions on 3 different knives) all for the cost of shipping alone. I do own a SMF that I've had for about 7+ years of almost daily use that has never developed lock rock. I have seen lock movement when some oil got on the lockup but that is it. I have experienced some sticky lock with brand new folders that went away after break in. I currently have about 7 Strider folders that exhibit none of these issues that you mention out of the probably 30 or so that I have owned or come into contact with.
Do you own Strider folders, do you have personal experience with these issues or..??
Ok so if the knife has lock rock that means that it does lock up. Meaning that the lock bar has to engage the tang, otherwise the knife would just close shut like a slip joint and be unable to have the lock rock that you mention. Is it possible that the lock up is just super early like you see on a lot of them? The opening/closing and use that I mention will allow the Titanium lock bar to wear some to where it makes better contact with the tang. Once it does this there should be no more lock rock.
I don't know if it's the angle at which they finish the lockbars or the tang and they just do not perfectly meet up right from the begining or if it's bumps or grooves on the Ti that need to be worn off until they meet up perfectly. But I do know that many Strider folders require a well documented break in period and that many new Strider folder owners have complaints similar to yours that often get worked out after a break in period. I have seen this over the course of many years of reading forums like this one and the USN, etc. as well as plenty of personal experience with the knives.
I have seen on the Chris Reeve shop tour videos that they take the extra step and appear to machine the lockup of their knives. I believe this gives them later, more solid lock up and you don't hear much about CRK break in periods like you do with Striders.
I wouldn't recommend bending the Ti ever. If you like the knife and want to keep the knife, get $ from the trader and send it in to Strider if that is what will make you feel comfortable. You stated that this is your last Strider ever pretty early in the process so if you are that unhappy with the knife I would initiate a trade back with the other guy. It is up to you, but once you modify the knife it is rightfully yours.
