Brutal. Few have made more lasting contributions to how people PLAY yo-yo through their craft and ingenuity than Frank. And he was a real nice guy to talk to. Still remember opening y 1st Bare Bones and thinking how impossibly solid and massive it felt. I’ll def be playing that one today.

R.I.P Mr. Frank.
I often used Dif konkave bearings, And they always didn’t disappoint me.
It’s too sad that the person who made a great product left.

Bad day. I hope someone close to him shows this topic to someone in the family, so they feel comforted by everything.
He is a guy who left a HUGE legacy in our much-loved sport/hobby. Without his ideas, yoyo wouldn’t be what it is today.
Go in peace, Frank! We will miss you!

Awe man, this one hurts. I grew up near Frank in Massachusetts and he was a big part of my life when I was starting off in the yo-yo scene. Every time I would see him at a meetup or contest he would stroll up, reach into his pocket, and pull out some new model for me to try out. Just so friendly and welcoming. He was truly an innovator in the early aluminum days, and he was able to machine smooth yo-yos when other manufacturers were struggling with tolerances and vibration. The unresponsive revolution would’ve looked a lot different without the introduction of the konkave bearing as well. We owe a lot to Frank. He was such a kind, gentle, humble dude. I will miss him a lot

My condolences to all. I didn’t know him personally, but have enjoyed many of his yoyos and bearings over the years! Throwing one of my favorites this morning to celebrate the man and his great art that he’s gifted to the world.

Bummer, he innovated what I consider to be the best bearing. Never met him in person, but I was privilege to do a couple transactions with him with pieces from his personal collection, He means a lot to this community, RIP

Huge loss for the community. Sounds like he was a great person and he obviously played a key part in modernizing yoyos into what we have today, both because of the Konkave and some of the designs of the throws his company produced. He will be missed.

Sorry to hear about Frank, very sad news.
I hope you find a way to forgive yourself. I find as I am getting older the more “Ghost’s of bad decisions” haunt me like a Christmas Carol.
