Traditional pinning tweezers require you to apply continuous pressure to a pins in order to hold them in place. That's where these cross locking pinning tweezers differ. Instead, they work in reverse.
Squeezing opens the jaws to allow you to grab or let go of a pin. When you let go the tweezers clamp down on the pin and hold it without any additional intervention.
This is ideal when pinning or gutting a lock because it allows you to focus your attention on placement of the tweezers without also having to worry about keeping a good grip on the pin.
