size and the tool info is right there in the second pic (it took me a second to see the tool, so as a hint, it's in the top right corner)
no dimensions listed for the DP skull, only for the folder.
however i expect the hex that's the "nose" is .25" across the flats.
my only question is where is the lanyard attackment point on the folder, or is the lanyard for the Mr. DP skull tool?
with that deep carry pocket clip i'd expect the option of adding a lanyard to fish the thing out of your pocket.
