Small story...
Back in the '70s, as a medic in a US Army battalion aid station near the DMZ, Korea—Think MASH-unit.
Late one night, during my shift as an ambulance driver, we got a call from the front gate. A ROK (Republic of Korea) soldier had severely injured his hand and was bleeding profusely. The gate guards asked if they could send him up for treatment.
We said yes, he arrived shortly after. Upon examination, we saw that his right hand was cut down to the bone on the small finger side—what some might call the "knife edge."
He was drunk on the local homebrew, Soju (소주)—pretty harsh stuff, at that moment, a decent anesthetic.
He wasn’t feeling much pain. His English, limited, kept repeating, “I f**ked up.”
We asked one of our KATUSAs (Korean Augmented to the US Army) to translate and find out what had happened. KATUSAs worked with us and spoke English—a good gig compared to serving in the ROK Army, where conditions were notoriously harsh. (The ROK soldiers weren’t exactly fond of the KATUSAs, either.)
The KATUSA explained that the soldier had been showing off to his girlfriend and decided to try cutting a Soju bottle in half—with his bare hand.
Because why not?
Like many things, probably sounded great in theory.
We sutured the hand, using subdural sutures to bring the deep edges together, followed by external sutures to close the wound.
Moral of the story: trying to cut a bottle in half with your hand is
maybe not a good idea.
