Hello, my name is Frank Difeo.
I've made my living as a Tool Maker in the machine shop trade since I graduated from Trade School in 1970 and, for the past 8 years I have run my own small machine shop on the side.
I always enjoyed making things from metal and especially making things that were custom or out of the ordinary.
A few years ago I got hooked on collecting Vintage yoyo's and something that came as a surprise to me at the time was when I discovered Aluminum yoyo's ... with ball bearing axles even !!
I still didn't become very interested in the metal ones until the economy slowed a few years ago and then I had some slow times in the shop and started to tinker with making Aluminum yoyo's.
As the economy continued to slow I had less work and more time and ...
Well, .. one thing led to another and I started making more yoyo's and concentrated more on improving the way a yoyo functioned.
My thoughts centered on the problem of the string rubbing the sides of the yoyo and concentrated on making the Grooved and KonKave bearings to improve that inherent down side as I saw it. As for the different Dif-e-Yo yoyo designs ... I start with an idea and experiment ... first and foremost ... with something that functions and then incorporate a visual design to compliment it's function.
Thanks to all that enjoy Dif-e-Yo yoyo's.
Your positive response is Greatly appreciated.
You have made Dif-e-Yo what it is so far.
Thanks also for taking the time to read this brief History of a person who has become addicted to yoyo's and I hope to be able to keep making yoyo's for people to enjoy.
