The picture is of a standard tool adapter, not the newer UTA I'm afraid.
It's like the one on the left in the following pic. The description he's given is for he UTA, like on the right n the pic below.
The Standard Adapter will work with the older Leatherman tools i.e. PST, PST II, Supertool, Minitool, Sideclip, Flair and Pulse. It also works (just about) with the Supertool 200. It won't work with the original Wave or any of the newer tools.
