While no yoyo can truly come out unscathed if you were to fall on it or step on it, here are some of the most durable yoyos I can think of. For durability, I tend to think of yoyos that don’t have sharp, thin edges, as those can bend or dent easier, but more rounded, thicker walls and rims. A thicker axle will help as well.
-Most Side Effect enabled yoyos, no matter how you beat them, they won’t gain vibe unless some part is bent, the one’s with thicker walls will be able to handle more. The GZR editions are especially tough, as they are made from 7075. These are the ones I think are the most durable.
-Dif-E-Yos- They have an amazingly high tolerance for being knocked around. Thicker walls and a thicker axle lets it take all the abuse.
-The PSG- An extremely durable yoyo. It was run over by a car as a test, it was damaged, but I’ll still give it credit for being playable.
-Duncan Freehand 2- I’d give this one credit for being the most durable. The updated version had thicker hubs and thicker walls. The plastic itself is very durable as well, won’t crack easily.
There’s more out there, but I think these are at the top for durability. There are throws that have rubber rims and such. But I don’t think it would be fair to add those to the list lol. I didn’t add a lot of YYJs, because the hubs on those were know for cracking, and the parts are not as replaceable.
