Raised spring with blade open

Is there any adjusting the spring to be not sticking out when the blade is open? As in without removing the blade from the knife? My favored Case sowbelly has the main blade pushing the spring out just enough to have a raised sharp edge on the back.
 
Send to a modder?
Send to case for warranty?

To fix without weakening the spring or lightening the the pull, the tang will need shaving on the portion in contact with the spring when open. ☹️🥺
Filing the spring flush would not be a good idea. At least not in my opinion. (also, if it is flush when closed now, it would be sunken after filing.)
 
I think the way to do it is by filing at the part of the tang that is in contact with the spring while open. Very little at a time. Proceed with caution.

That's what I was thinking but wasn't sure I was overlooking something obvious. Not sure what tool would get in there to only a bit at a time work at it???

Again, what I was thinking. Definitely don't want to weaken the spring any or have it sunk inwards.

If you google for a bit I think you can quite easily find a file small enough. Maybe jewelers tools? Or sandpaper even. I’m no expert in the field though.
 
I’d recommend trying some fine sandpaper on the back of the tang where it mates with the back spring. Maybe there’s just a burr or if not a minimal amount you could sand away to bring it to flush. I would absolutely not recommend modifying any other part of the knife! Good luck

If you adjust it so that the spring is not proud when the blade is open, the spring will be below the surface when closed, and you will have the sharp corners of the other two surfaces exposed.

Another option in place of such an adjustment is to use something like the corner of a Sharpmaker triangular sharpening stone to round the edges of the corners of the protruding spring. It will still protrude, but will be less noticeable to your hand.
 
For the spring to lay lower you need to remove steel from the tang. That is hardened steel and will be hard to do without taking the knife apart.
If you realy want to use a thin and coarse sanding stone like EDM or Bellstone. I'd try 180 or 240 grit first.

I think the best advice is to send it back to the factory, it should never have left it

My close up pics always stink. But at least this hopefully shows my issue.

Or is this normal???
 
In my recent experience Case said that is acceptable. Their tolerances are not subject to our (consumer) interpretation. They may just send it back to you as is. Be warned.

That looks like factory error. The blade isn't opening to the position you'd expect, which is also coincidentally why the spring is raised. I'd try to get a replacement, or if outside of the return policy a warranty repair.
 
Looks like they forgot to grind the spring to the proper length, it appears to be too long. hard to say without seeing a pic of the entire knife with the blade open. If that's the case you may be able to file a little bit off the back square right at the end of the blade back where it drops down. This will basically accomplish the same thing as shortening the spring. You should be able to reach that area if you open the blade halfway assuming that you have a cam tang on that knife. This will only work if the spring or back square are cut at a bit of an inward angle. If they're both basically squared off it won't work.

With that said I'm not sure you'd be able to take enough off to have the spring completely drop without bottoming the parts out, it's quite proud there.

This is the thing I'm very picky about, if the spring isn't flush on open it's uncomfortable to use the knife (either if the spring is raised or sunk) The one you have is well proud so I would try returning it. I'm not too convinced by all the filing remedies, it will foul the joint with filings and be very difficult to achieve, could worsen things even.
 
Leaning away from wanting to try sending it back to Case. Is there a vendor here that offers this kind of clean up service?
 
I should add that the main blade is the only one of three that has this issue. Of course the other two are perfect.
