Recently got a 350 that someone acid washed and put some new scales on. Blade is off center to the point it is rubbing on the liner. How do I fix this?
 
There could be a number of different possible solutions, depending on what the specific issue(s) is/are.
1) Which liner is blade contacting?
2) Does knife still have torsion bar installed (assisted opening) or has knife been de-assisted?
3) Is there any blade play (side to side or up & down) when opened?
4) Are any of the fasteners loose (any except pocket clip that is)?
 
Blade touches no locking liner. Side to side blade play but no up and down. Torsion bar still there. All screws tight except for pivot. It's as tight as it'll go without impeding the assist action
 
Assuming "Blade touches no locking liner" means touching non-locking-liner, and that you have side-to-side blade-play, and no up/down play - would indicate that the liner-lock is pushing the blade over because the pivot is loose. You say pivot is only loose enough for smooth operation, I would guess your pivot assembly is dirty and needs cleaning to allow tightening the pivot to center blade, while still being smooth.

My 350 (& each I have worked on) had zero side-to-side and easily flicked open (de-assisted) with finger-flick, marble-shoot, thumb-flick, etc.

If you had said no side-to-side I would have said maybe a resetting of all screws, liners, etc. was in order (typical when knives get reassembled haphazardly).

Try to center the blade by tightening the pivot. If it centers, I would stand by my first comment above (pivot ass. needs cleaning and adjustment).

If whoever did the acid-wash did not properly protect the critical pivot area, blade-tange lock-face, stop-pin-interface ... well, there could be lotsa prob's going on with that knife (hopefully just needs a cleaning).
 
I'm afraid there maybe lots of problems with this knife. The acid stone wash that was done looks to be a rush job and very sloppy. The pivot area on the blade wasn't neatly protected and the interface you speak of wasn't protected at all. I'll try to clean that area up as you suggested just to be safe. Thanks for the help guys

Hmmm ..., seems my thoughts hit nail-on-head.

Sorry to hear. I have had a number of knives come through my hands that have been f'd by previous owners who attempted to "fix" or "improve" on factory design & manufacturing. Sometimes they can be fixed, sometimes they simply become expensive parts knives, or ate traded to the uniformed :-/ Hopefully you do not have much invested into this one :-)

Regardless, follow my earlier suggestions and maybe you can come to a place of acceptability you can live with on this knife ...?
OR
PM me if you'd like any additional help with repair on this one.

Regards,
Christopher
 
Worst case you could get a replacement blade from ZT for a nominal fee.

That almost looks like it's missing a washer...

I was gonna say the same thing ...

In the pic's if the pivot area, it looks like possibly the torsion-bar-side (small diameter washer) is either missing or has been exchanged with a thinner washer/bushing.
 
Spey it won't let me view. It does have both washers. Very thin. At first I thought someone over tightened it and smashed the washer as it is very soft
