Pin ideas?

[Gr3yGh0st]

So, just bouncing some ideas around here, but I have a few ideas for driver pins to increase picking resistance.

1. An hourglass shaped pin with serrations on both sides of it. Would probably function like a serrated spool

2. A serrated T-pin

3. A standard pin diagonally cut with the key pin as to have two shear lines in the same chamber. The key would need to slightly lower or rise to accomodate this.

4. (For wafer locks) A sidebar type mechanism with false gates. (Probably done before.)

I just had that idea when I first saw the serrated pins.
Why not use movable serrations?
The pin like a spool with very thin inner core and than "rings" around that core which can move horizontally so under tension you have multiple shear line blockings but the pin staying more or less horizontally making it impossible to push it further and not causing counter tension on the bolt, so you have to set the pin in one try to the exact right position before applying tension...

i once got a longish spool pin and managed to get a spring around the center with light tension the spring acts like a serated pin and with heavy tension it acts like a pin with a spring wrapped around it nasty

Such a pin has been made by DOM. You can see on position 2 and 3 such pins her:

I already picked some locks of DOM. Although these pins are pretty complicated, they offer far less resistance than expected.
