For me, eating and writing are the few things I'm only good at doing left handed. Knives are left handed as well. Scissor use is always right handed since most scissors are right handed, using left hand scissors is hard for me. Sports are always right handed for me. Tools are usually ambidextrous. My left hand is more dexterous but my right is stronger so my dominant hand just depends on what I'm doing with the tool. Using an xacto blade to carefully scrape solder mask off a board? Left hand. Turning a difficult screw? Right hand. I think the defining thing for me is that if something is specifically made for right handed use or if you're more likely to encounter a right-hand version, I'm probably right handed when using/doing it. If it's ambidextrous like a pen or fork, I'm usually left handed.
