Unknown Square Counter Weight
This 3D printed counterweight makes use of the "lock and key" technology to make it fast and easy to add and remove from your string.
This is the first counterweight from Unknown, the design brand of 2010-2013 US 4A champion Brian Figueroa. Brian is responsible for many logo designs in the yo-yo world, and now he's turned his creativity to product design as well.
Its biggest feature is known as the "Lock and Key" technology, a method to make it super easy to attach and remove the weight from the string. This makes switching back and forth between 1A (string trick) to 5A (counterweight) play feel like a magical quick wardrobe change. Its two-layer construction is another key design point, highlighted by the different colored materials used.
Weight: about 10 grams, with tiny variations between individual units.
