Splinter movement

Got several splinters in my hand in the most awkward places today. Luckily a co-worker had a swiss army knife on the ready, complete with tweezers and a pin. The mill I was working in was built in 1662, but some bits of wood (oak) including these miniscule ones date back from a little before. The tree was approximately 30 years when cut down. So we're looking at some wood from at least 376 years old. That's what I'd nearly call archeology digging into a finger like that.
