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.
