I picked up a bunch of used Rigid power tools back in 2020. Included in it was a circular saw. I already had a Rigid circular saw, so I never thought much of it, until one day I could not find where I had left my original. I grabbed the new (to me) saw and was using it and cursing the entire time about stupid right-handed tools.

Later that day I found both saws and stuck them next to one another and realized the newer saw was left-handed. I guess I had been using the other for so long it was odd to use the correct handed one.

I’m left handed, but I don’t own any left-handed items.
I make do.
I play the guitar, use a mouse and eat like a right-handed person.
I write, shoot, and do most other tasks that require fine motor control with the left.

I have a few left-handed guitars. Turns out I was just having a mid-life crisis and not a genuine desire to learn how to play guitar.

I am right handed but I always use the Thinkpad nipple with my left hand. I tried switching the click buttons to make it properly left handed, but that made it way harder to use because then the primary click button sits on the right and I have to reach my thumb over. With the right handed settings my thumb is right on the button.
