If the blade lock up is secure (spine whack test passed?) then it's OK... maybe not optimal, but OK.

Your lock is at the end of its life. It's fine if the lock is secure and there's no blade play. But when the lock wears just a tiny bit more, blade play will start and the lock-up will be compromised.
Liner locks are designed to wear across the blade tang. When they hit the far side, they're at end-of-life. Some makers rehabilitate worn liner locks by introducing a slightly bigger stop pin, which will send the liner back to the left again.

Have you checked to make sure the pivot has not just gotten loose?
If the lockup degraded that rapidly I would bet that's what it is. Tighten the pivot up again and see if it improves.
Unless of course you have been flicking the knife. A lower end liner lock that is flicked a lot could easily degrade that quickly.

You should probably check all the screws first to make sure they're not loose, and check the stop-pin as well to see if there's anything wrong with it. A well-built knife like the Seki-Cut line up won't degrade that rapidly, although there's always the possibility that a bad one slipped through QC.
Also, if there's no blade-play, it shouldn't be a problem. It may be that the tang is cut such that the locking liner "settles" in that position, i.e. it won't wear too much afterwards.

Speedfan,
You can do a search and find tons of info on the spine-whack-test but here is the quick low-down:
No, it will not damage your knife in any way if done properly.
Understand that you don't have to apply much force to the spine of the blade. It's really to test the locking geometry and NOT the actual lock strength.
Just take your knife by the handle (with your fingers safely out of the blade's path if it should close), and firmly strike the spine of the blade on a padded (but hard) surface. I perform this three times consecutively.
If the lock is bad the blade will fold.
And when you get a bad lock, it is simply amazing how easy the blade disengages and with how little pressure.
Good luck,
Allen.

Tom makes a good point about the stop pin.
In some cases if the the stop pin is not perfectly round or has been flattened from flicking and/or not being hardened properly, it will increase lock travel. Try spinning the stop pin 1/4 turn and see if things improve.
