I'm looking for some advice. I have a Case XX 62024 1/2 with a pen blade that won't open so that it is straight and it's bugging the heck out of me. I have an older one that opens straight out. Is there a way to correct this without taking the knife apart? I'm guessing I could grind some material off the spring or blade tang (the area I've seen referred to as run up or back square) but I'm not sure how to do it without marring the bolsters or liner. Any advice is appreciated.

It looks like when the knife is half open, the edge of the spring is flush with the tang of the blade. That does make working on it as-is a tough go. The easiest way is obviously to remove the pin on the spring so you can swing it out of the way and get at the end. You would take a jewelers file and file down that end until the blade sits more level.

You may be able to do that without taking things apart, but that is the easiest way.

How about when the blade is closed? Does the end of that spring stick out past the blade tang? If not then you may be able to get that jewelers file in there and shave that tang down. Just keep in mind that anything you do to the blade tang or spring may affect the way the spring sits after.

Anyway, that's how I would tackle it. There may be another way to skin that cat, though.
 
Thank you for the advice. I'm going to look for a better set of files and see if I can get in there. Thank you.
 
I haven't done this but :

Couldn't ecallahan send the knife back to Case and have them do the right thing ?
Or do the thing right.

For the many knives I have bought they have been nearly 100% quality wise out of the box so I am really surprised to see this.
 
There may be a position (closed or partially open) that exposes the rear of the blade. If there is, the blade can be filed or ground down using the flat of a separating disc or diamond disc in a handheld grinder.
 
I went after an inexpensive marlin spike knife attempting to get the silly spike lock to ACTUALLY go into the notch and lock. It was an exercise in futility. I am extremely "handy" when it comes to metal work but I must admit to failing that one. Though I really thought it could be pulled off. If it were a Case I would have sent it to them. As it was I don't think the Rough Rider dudes that make the knife even realize the thing should lock they are just putting in their hours . . . knife assembly line . . . lawn mower assembly line . . . no dif to them.
