question regarding theory behind SFIC fingered torque tool

[thelockpickkid]

your problem in understanding lies here

The torque tool in question has little fingers that reach into the little holes on the bottom of the lock and grab the middle cylinder, supposedly applying torque only to the control line.

it does not apply pressure to only one, it applies pressure to both, meaning that the inner and middle cylinders that would creates a shear line now move together as one... making no shear line... only the outer cylinder has a shear line now...

hope that helps

What? No shearline? What a load.......You don't even know how these locks work either.

Reread the post, he is saying the shearline is at the control sleeve when you are turning both together with the icore wrench.

Thanks CaptHook

maybe I should have been more clear, I appologize if I was not clear...

what I was meaning(as CaptHook mentioned) was that; when using these tools, there is no shearline between the inner plug and the control sleeve. there is only one shear line(instead of 2), it is between the control sleeve and the lock body.

the reason they are hard to pick is because 1 pin can align up to any one of 2 shear lines and unless all the pins are lined up with the same shear line the lock will not open. when we limit the amount of shear lines to one(using these tools when applicable) it is no harder than any standard lock.

is that a better description?

Yes. thanks! I am an @ss!

The peterson tools require shims except on a few keyways. They recommend flat toothpicks. Both shearlines still exist. The control is just supposedly more pronounced in the locks you can utilize these tools. I lost them to the collection in favour of luck. Just as applicapble as cramming toothpicks in the keyway all the time to get a better feel... for a lock jammed up with toothpicks.

lol

hence "When applicable"

I never was a fan or luck when picking but with these jewels it seems to be the best way. I prefer top tension so these tools dont suit me well. (do own a set, used em twice)

i didn't know that tooth picks were commonly used. i've been using some plastic ones. thought it was just me though lol.
