Crescent wrench is more or less a genericized trademark like Kleenex where I'm from.

I don’t think anyone is saying it’s a brand of wrench. Just that it is a generic term for a very different kind of wrench with an adjustable jaw. Famous for rounding off the corners of perfectly serviceable nuts, bolts, and all manner of pipe fittings. The wrench in the logo is an open end wrench (typically would have a closed end wrench on the other side)
