After suffering through many episodes of painful thorns and splinters, he decided to create his own portable Splinter Kit that he could carry with him while out hunting, or working on fence, or splitting firewood. While all his friends suffered until they could get back home to deal with the nuisance, he was able to forego the delay and the subsequent soreness, and immediately eliminate the source of the problem. The real trick is to get the thorn or splinter out as quickly as possible, before it becomes so sore, you can't touch it.
I'm not revealing anything new or revolutionary; for centuries people have removed thorns and splinters with a needle. Heck, even in Lonesome Dove, Deets removes the Mesquite thorn from Jake's thumb with a needle he carried in his gear. Somehow, we've lost that example of common sense and practicality---something we are going to need lots of when the SHTF scenario happens. In fact, the little tin can that PLW bought to hold his supplies only cost him $1.20 on one of his favorite prepper sites. And he scrounged everything else from our stockpile of medical supplies at home.
He carries one with him in his GoBag that never leaves his side, and another one is stashed in the more comprehensive BOB for a bigger event. So there's no excuse! It's not rocket science, but it sure provides some timely relief.
Isaiah 10:17 "The Light of Israel will become a fire, their Holy One a flame; in a single day it will burn and consume his thorns and his briers."
