"I find your lack of faith disturbing." |
Has anyone had a problem with the latch wearing the titanium thin and therefore making the locking mechanism loose? I haven't but wonder if this could be a potential issue "I see you have constructed a new lightsaber." | ||

No, not really. There's some very light wear at the point where the latch slides over the handle to lock it closed, but only enough to wear off an almost indistinguishable amount of the anodizing. The only real wear so far is on the underside of the "button" of the latch, itself. There are two shallow grooves on either side of the "post" part of the latch. The spring mechanism is, of course, the liners, themselves, with a hole drilled on each side with a rod that fits into the holes in each liner, and the latch pressing down on the rod. I've never disassembled it to see whether the rod has wallowed out the holes any yet, but that could be the biggest concern of the mechanism. It seems to me to be the part that gets the most stress/pressure. ************************************************************************ Charter Member #9 and Skullmaster °„° Lum Lunatics Brotherhood of the 420 Boomerangs 'n Butterflies: An Osborne Alliance | General, and Member #950 Pardue Pimps® #3 Jack of all Trades, and Good Enough to get Paid for All of Them. ************************************************************************ "No time for the old 'in-out,' luv - I've just come to read the meter!" -Alexander DeLarge (Prisoner Number Six Double Five Three Two One) | |||

My 51 just came in off backorder today. I'm kinda hoping it hurries up and wears the last soon lol. I picked up a used 32 that I took apart to move the clip and I didn't see any wear in the mechanism. The rod that the latch presses on doesn't actually touch the walls of the holes in the liners, but instead there is a pin that goes in the holes in the liner and the rod is a sleeve that goes around that and sits on top of the liner. | |||

Yes, that's right. I guess I wasn't clear. I might take mine apart tonight to see whether there's any appreciable wear, but I doubt there would be much. After all, we're talking about hardened Ti and steel here. They're both pretty hard  ************************************************************************ Charter Member #9 and Skullmaster °„° Lum Lunatics Brotherhood of the 420 Boomerangs 'n Butterflies: An Osborne Alliance | General, and Member #950 Pardue Pimps® #3 Jack of all Trades, and Good Enough to get Paid for All of Them. ************************************************************************ "No time for the old 'in-out,' luv - I've just come to read the meter!" -Alexander DeLarge (Prisoner Number Six Double Five Three Two One) | |||

As far as I understand tightness of locking mechanism is provided by bite handle liner. There is a barely visible slit in liners near to latch. When you close the knife and lock the latch, a small lever on the latch will bend the strips on both liners like a bow. While knife is closed, bended stripes are trying to straighten themselves up and this force is applied back to the lever on latch. It seems there is much more force being generated than in spring loaded latch. The question is how resistant to bending fatigue is this stripe of titanium liner. Since bending is of very small amplitude and there are actually two liners I think it will last for a long time. But of course it can break. ---------------------------------------------------- 42, 42SS, 42-400, 43, 43MC, 46MC, Balibalistic TAC-U, DR Venturi V82 Tanto I have two pets: a large main cat, and a small emergency backup one. | |||

Yes, the latch presses down on the rod/sleeve that is fitted into the slit or hole in the liners. So far, it has been very reliable, but, to answer Jedi's question, I haven't seen any wear to speak of on the mechanism. ************************************************************************ Charter Member #9 and Skullmaster °„° Lum Lunatics Brotherhood of the 420 Boomerangs 'n Butterflies: An Osborne Alliance | General, and Member #950 Pardue Pimps® #3 Jack of all Trades, and Good Enough to get Paid for All of Them. ************************************************************************ "No time for the old 'in-out,' luv - I've just come to read the meter!" -Alexander DeLarge (Prisoner Number Six Double Five Three Two One) | |||

I can't think of any application where the Ti would end up being "thinned out". "Best that could happen": "Thinning the pin on the latch itself". I mean, it isn't made out of Ti, IIRC  Regards, Julian Benchmades: #1100-1 w/2nd gen clip, 3300, 3300BK, 760LFTi, 32, 46, 51, 51, 51-91, 755 MPR Spyderco: Szabofly, Smallfly Trainer Bradley: Kimura II SS Limited | |||
