I carried a folding pocket knife in my pocket for a really long time. Eventually, someone educated me that multi-tools (that include knives) exist. I carry this everywhere now instead of a knife. This is a lot more useful than a folding pocket knife: https://www.gerbergear.com/en-us/shop/multi-tools/all-multi-tools/suspension-nxt-black-30-001777 - You may still have plenty of uses for a fixed blade knife in addition to this, but getting some kind of multitool (I am not a fan of Leatherman), is a good upgrade to a daily carry knife.
Never carved anything into a tree; that's fucking dumb.
