I thought the No Jive was a metal axle with a ball bearing, considering Tom Kuhn was one of the first yoyo designers to throw a ball bearing in the mix. I dunno, Ed will probably have to reply to set the score straight, wonder if his spidey-senses are tingling considering how we are discussing his favorite yoyo.
Anyway, I’ve had no-jives. They are wooden axled yoyos. Actually it is a fixed metal screw with a wooden axle sleeve over it. But thats getting technical even for me.
A wooden axle plays much differently than a metal axle due to the wood grain. One thing to do w/the wood to smooth it out a bit is to wrap a length of string around the axle leaving enough on each end to grab. Pull it tight and pull it back and forth a few times to remove the cluff and small splinters from a new axle.
