I have a very distinct memory of my first lab job in undergrad, this random very old man came in to talk to my boss, and he stopped and watched me work for a second and goes “Where’s your knife?” To which I’m confused and he says “Every biologist’s gotta have a good knife” and pulled out a very nice very sharp pocket knife which did help with whatever it was I was doing.

I still haven’t bought myself a nice knife. I guess I’m not a true biologist yet.
