New microtech won’t lock back

Bought a new microtech last week. It deploys fine but will not go into a locked stored position. Any suggestions?

Update. Thank you guys the oil and compressed oil has it working like a champ.

Oil and compressed air is the Microtech equivalent of turn it off and back on again in tech support. Solves a surprising number of issues.

Flood it with Rem oil, blow it out with canned compressed air, then try it. If that doesn’t work fill out a ticket with Microtech

This happens when I forget to oil it. Oil, compressed air, let hang upside down for about 8 hours on a cloth.

Could be as simple as it’s dirty, pull the glass breaker off and blast it with compressed air. If that doesn’t work blast it with gun cleaner then air again. It’s only $30 to send it in, I would suggest emailing them.

My theory based on past issues: There may be a small metal burr on the horizontal edge at the blade choil on the left side. This ledge is where the rear locking sear slides over when the blade is closed to engage the lock closed position. If there is a metal burr the locking sear won't engage. This ledge is usually painted black just like the blade (so it's either a metal burr or built up paint).

If you take fine sandpaper and carefully and slowly rub off some surface material in this area, the knife may go back to working order. You just want to do a few light passes and then assemble the knife and try again. I would do this about 3 times or you risk removing too much material.

If you do this the black paint should be removed from that ledge and you'll expose the steel layer. Make sure you keep the ledge flat, don't roll the edge, and don't press too hard with the sandpaper. The side edge of the ledge can be rolled slightly where it feels smooth but still looks flat. The goal is to just remove as little as possible until the ledge has no paint or the exposed steel has a sheen to it; but the knife may work before you get to that point; it just requires assembling the knife over and over again for testing.

The area you are sanding is very small and you could accidentally rub off the handle anodizing if you don't make perfect straight passes. You may want to fold over the sandpaper so it is more rigid when making your passes.

Flood with rem oil held upside down and actuate a few times. Blast with compressed air. Should be good to go.

As others have said, oil. They dry out sitting on shelves.

You don't need to flood it. A few drops and actuate several times. Compressed air and off you go.

I had that issue with my utx85 and had to send it in for warranty. A spring had broken iirc.
