Judging by how many couples' initials are carved into trees, it's surprising how many people bring a knife on a date. amirite?

I carry a knife with me everywhere I go

I always just used my fingernails

People bring the knife with the intention of carving in a tree. It's not a spur of the moment kinda thing.

You don't carry a pocket knife?

Ehhh or they use a key!
