He mostly did that just for testing purposes. He primarily uses multi-tools. He's seen most times using the Leatherman Wave and the Victorinox Spirit.

As it stands now I have 14 Swiss Army Knives, 5 Multi-Tools, 3 Fixed Blades and 22 Folders.

And yet like Scafool said I find myself using the same two 90% of the time. Leatherman "New Wave" and the Benchmade "Ritter RSK Mk. 1 Griptilian."

Is that all?
