BLADE STOP PIN extend its life x6

How about we just use the knife in the way we want to do so, and if the pin one day gets deformed, request (or pay) for a spare stop pin from the manufacturer and have it replaced ourselves.

And if the manufacturer does not provide the pins or spare parts for self-repair, remind ourselves that the knife has served us well for many years, put it aside and get a new one. :D

And other people driving..don't forget that part. If you flip your knife against manufacturers recommendations, then that is on you and is yours to do with as you please, but I wouldn't expect exemplary service when this bit of information comes forth.
 
My TSF Gorgon has a cammed stop pin. I believe Jim is putting them on all his models now.

OK. So the pin is a hexagonal prism, or there is a hex screw that allows one to rotate the stop pin? Or both? Help!

Yes, you can rotate the hexagonal stop pin to give the liner locks more life. The 320 Precinct is like this as is the 765 Mini Monolock. Probably some others but I'm not sure.

OK. So you can rotate it to any of 6 positions to get a fresh spot for the blade to hit.

Would not, then, an octagonal stop pin provide even more spots?

Or am I missing the core concept?
 
So the hexagonal stop pin looks like this....a heaxagonal prism, correct?

Is has six sides and can be rotated, the pivot pin on the benchmade vicar I got from cray has one. I think the more sides, the smaller each side has to be in order to remain the same size, the smaller the side the less contact with the tang I would think.

I haven't been able to evaluate how effective if at all the stop pin actually is yet, if I keep the vicar I'll let you know if the stop pin performs as advertised.

Anyone who wants to rip the OP for his op as being "unnecessary", keep in mind that we have liner locks, Reeve's special take on liner locks known as "frame lock", Axis locks and variations, etc.
All of this when a lockback style that has been around for ages would do just fine on the same knife.

Reeve doesn't want people flipping.
Someone thought of an idea to prevent a problem that seems to exist based on what a guru has said.
Kudos to him for at least trying.

like on the Benchmade 761??

Super helpful! Thank you!

So. What is better for a stop pin: less sides/less fresh spots but more area for the blade to contact, or more sides/more fresh spots but less area for the blade to contact?

Maybe that is the "core concept" I don't know.
 
Don't forget the effect of long term wear on the hole the stop pin sits in, over time they will elongate from the constant hammering as the energy from the tang to pin and the pin to frame. Everything wears eventually, the only way to prevent wear is to never use it and there are plenty of safe queens out there that'll never wear out their stop pins. ;)

Looking at the photo, I don't think the concept of the hexagonal stop has anything to do with a "fresh spot", but rather minute changes to where the blade is stopped as means of altering where the lock-bar sits against the tang (how far it travels, late vs early lock-up). By rotating the pin from a flat plain to a vertex one can adjust the lock position from early to late to find a "sweet spot" that the manufacturer couldn't figure out how to give it at the time of construction. This will also help compensate for wear at the tang/lock interface which is a FAR more notable problem than "stop-pin wear". Seriously, worn stop-pins??
 
In Benchmade 913 you can rotate stop pin and this way adjust your liner lock. I think that Emerson should use that idea.

I'm unsure about that...

I'd imagine a hexagonal pin would fit into a hexagonal hole, thus limiting contact to a flat plane. I could be wrong, maybe the ends are cylindrical.

Like T said, you'll still have forces acting upon the "other" end. No matter what, the wear is not limited to the blade tang and pin.
