I used to work in a restaurant where the thing that held the knives was agnostic about which direction the blade faced. It's quite beneficial to know which direction the knife is facing when grabbing it, so we wanted to establish a standard. There was a lengthy discussion about which was better, we picked one, then we had to train the rest of the staff and remember to tell new hires. And people still forgot, so having a standard was pointless. If the knife storage had been opinionated, we would have expended no effort and achieved consistency. The choice of direction was essentially arbitrary, but making a choice and sticking to it was valuable.
