Max Manus' Stapler

Origin
Max Manus was a Norwegian resistance fighter and saboteur during WWII. He specialized in watercraft operations and, using primarily Limpet Bombs as his weapon of choice, sank many German ships. Later in the war he moved to Oslo where he organized an underground resistance movement before returning to saboteur work in the later days of the war. Despite his horrific PSTD fueled nightmares, after the war he went on to found and run a very successful and still operating office supply company.

Effects
When documents joined by this stapler are brought about a vessel used for war purposes, in use or decommissioned, they explode violently. They seem to do so where it will cause the most damage, either to vital machinery or to eliminate a specific high-ranking individual.

Whoever used the stapler may experience bouts of PTSD depending on the number of individuals killed as a result of their actions, and it has the potential to haunt the for the rest of their lives.
