What's This Called?

[BluegrassBrian]

I've always liked the look and feel of folders with this style of.. lock.

When the studs (whether they are used for deployment or not) act as the "stop", in lieu of a stop pin mounted on the back.

Perhaps the most recognized knife utilizing this is the CRK Umnumzaan.



Hinderer also utilizes this style frequently..



So surely it must have a name?!

External stop pin?

Stud stop is what I call them. I made it up though. lol

Thumby Rubber Baby Buggy Bump Stoppy on the 'Zaan.

Flip Dippity Blade Stoppity on those like the Hinderer.

I suggest we just treat them like bellybuttons. Those are outies.

Stud stop or frame stop. I was put out to stud once. Now I'm out to pasture.

See, when two parts of a knife 'like' one another, they want to 'do' things together. Their bonding makes for a solid 'lock up'

I believe Butch Vallotton actually first used thumbstuds as the stop pin on the Chameleon models in the 90's, that's the earliest use I've seen.

This thread delivers like thumbstud to a frame! Solidly!

These studs are not thumbable, but they stop the blade in both directions.

These are all Darrel Ralph designs. Top knife (CUDA MAXX) has Camillus factory scales and a custom 5 1/2” blade. Middle (MADD MAXX) is a custom with a 9” blade. Bottom (MADD MAXX) is a custom with a 7” blade.

Spyderco subhilt,. Microtech Socom's use stud stops as well....Sure there are many more!!!!

 

[elasmonut]

Efficient design.

 

[LimpCroissant]

I've never seen a direct one-word name for them. I've always called them 'thumbstud/stop pins' or 'external stop pins' when typing things to my fellow knife nuts.

 

[BluegrassBrian]

Guess this explains why I've never come across an agreed upon technical term for it..

I appreciate all the input yous guys.

Clearly, you've misspelled it!

I'm not seeing 'x' or 'z'. Yes, they are silent, missing nonetheless!

On the umnumzaan it is a thumb stud serving dual purpose as a stop pin
On other knives it could just be a thumb stud or even just a stop pin(as in the Strider SnG),
