    Hi all.

    So I know it's just due to wear/tear, but my benchmade 42 Springer's latch is just barely holding the knife closed. Here is a pic to show what I mean:

    Is there anyway to midigate this? Something like a slightly shorter latch (Longshot I know), or something like shimming inside the channel where the back of the blade impacts when it closes ... Idk. Has anyone else attempted to address this?

    Is the latch pulled up over the safe handle all the way?

    Is your spring losing it's sprung?

    Better set her aside and go by more balis IMMEDIATELY!!!!! lol

    It's just that the two handles come together too much (wear and tear). It still works, but its getting closer and closer to just not latching over the safe side. Here is a video:

    For open position you could just install a new larger tang pin, but since it uses a kicker for the closed position, not much you can do. Might be able to glue some shims inside the channel where the kicker and/or back of the blade hit the handles. Only really other option would be trying to hammer the kicker out a little, or deform the metal inside the handle around the kicker to try and move some more material there.

    Yeah, those sound pretty invasive....

    I guess I'll let it be till I can't latch it shut anymore. Then I'll think about pounding the metal out in that area

    are the tang pin cups warn or the pins themselves?

    i had a tach 2 back in the day that was warn and the latch was loose

    wyldstyl3 machine pressed the pins to mushroom them out a bit and widen them

    worked very well

    something to consider maybe

    4x uses a kicker for the closed postion, so no luck there

    try slipping a thick enough o-ring on the latch and let it ride just below the head. this should simulate a shorter latch.

    They'll re-sharpen the 4x's, but that's about it, no spare blades or handles left. A reblade from a mooder would fix it though, could maybe get bushings too.

    Was thinking of punching a divot where the kicker hits to try to bulge the area. I just don't know if it would work.

    any good welders near you?

    you could possibly have someone weld a little glob on the kicker then clean it up with a file

    small area and shouldn’t hurt the heat treat

    is it 440 or 154?

    https://www.practicalmachinist.com/...welding-and-fab/welding-440-stainless-357086/

    just a consideration

    Well it's 154cm. Does that make a huge difference you think?

    I like that idea though. They would naturally weld the glob oversized, then I could just slowly sand it to size....

    I wonder if the continued impact to the handles would break the glob off though.

    With a proper weld it shouldn't. Since the contact area in the channels is hidden, might be a better option to weld there instead. BUT welding titanium isn't easy, and not easy finding somone who can do that for you.

    No idea,

    But i think if anything would chip away over time it would be in weld. Especially as that kicker beats the crap out of it.

    Maybe I'm wrong? What do you all think?
