Beskarman
The Beskarman was a type of advanced omnitool which every Mandalorian used, both on the battlefield and off. Karen Traviss for sure did not own one. Unlike the puny Mandalorian Army knife, it featured a lot of tools. Most clone troopers didn't quite understand what this thing was about, so they just compared the number of tools their Beskarman had, and the winner was supposed to have the biggest dick. As with most stuff made for real men, Kyle Katarn God invented it. So you can count every person killing himself with a Beskarman one more victim sorted out by the Almighty.
Danger
Because many clones did not know what to do with a Beskarman, because they were Mandalorians of lower worth, they often killed themselves with this tool. <insert name here> was known to have injured himself several times before trying to see if the Beskarman's laser nail file could improve the airflow in his lungs. Naturally, he died in the attempt.
The Beskarman in other Galaxies
In other galaxies, maybe that of those Yuuzhan Vong characters, there were also varied versions of the Beskarman. The Leatherman is one of those copy attempts.
