It is a Skeletool Hammer/Jammer. It fits onto the Skeletool to add a hammer, a light pry bar, a 4mm and 1/4" hex drivers, and an inline Leatherman flat bit driver.

Wasn’t really a fan of EDCing a Leatherman until I got my Free P2. I don’t like too much stuff in my pockets but this tool is so handy and the one hand opening of all tools is great. Sent from my iPad using Tapatalk
This is a big multitool. Larger than I expected. Only complaint is that it leaves black residue/paint on my hands.
