#venezuela 
That traditional and very Venezuelan toy was my favorite when I was a child, the boys in the neighborhood met to play and did competitions with them, which was the prettiest? Which was the largest, the one that cut the most; In my case I used to do it with soda caps (soft drinks) which I would smash with a hammer or failing that a stone and with the floor of the sidewalk I would sharpen its edge, to make holes I used a nail, I was looking for quite a string resistant preferably nylon, because the yarn, wick or cabuya always broke.

That toy evolved using large buttons, plastic covers, cardboard discs to make them, I've even seen them make them with CDs. It's a lot of fun and a healthy workout for kids, teens, and adults.
