I was just thinking about this. Why do we call yoyos made from a form of plastic and metal rims bi-metals? Shouldn’t they be called bi-material or metal rimmed yoyos?
Then, yes there are a few bi-metals. The one I can think of is the Catch22. Not sure off the top of my head of any other true bi-metals.

Not sure.
I really like to call them metal rimmed yoyos instead of bi-metals.

That’s what I’m saying. If you put bi-metal in other words, it would be something like “two metals” which is what I’m saying is generally incorrect.

Actually, we don’t do that.
Most people use the phrase “Metal-Rimmed.” Very few say “Bi-Metal,” and it sounds pretty silly.

I guess I have heard just heard it quite a bit. I agree that it does sound silly though.

I say it, because it makes sense. Bi means two or double, so two pieces of metal on the yoyo = Bi-Metal.

“Bi” doesn’t necessarily refer to two different types of something, very true.
However, when I say “The new Hyundai uses a patented bi-metal construction for the frame.” Most would assume it’s a combination of two different metals.
I guess it doesn’t matter though, since we all know what we mean.

I’ve always said “Metal-rimmed”, I never got why people referred to them as “Bi-Metal”.
Other examples of “Bi-Metals” would be the Night Moves 4 and 5.

Maybe bi-material was misheard

“Bi-metal” makes no sense to me because it sounds like a yoyo made from two different types of metal but I usually say it because it is the first thing I think of to call my Speeder I don’t know why

Don’t say Hybrid. It confuses people with the response type. “I’m looking for a Hybrid…” I may direct you to a Kickside, for it has Hybrid response.
