First released: November 2007


The One Drop Project Yo-Yo is designed, manufactured and supported in Eugene, Oregon by a partnership between One Drop Design and Designer/Yo-Yoer Colin Leland. This is the first yo-yo from One Drop and it is set apart by it's high quality craftsmanship, innovative design, and great play. It features a unique hex nut assembly which has the axle threading into a 4mm steel hex nut instead of into the body of the yo-yo. Advantages to this are: 1. If you strip the hex nut (highly unlikely given that it is steel), you just replace it instead of having a dead yo-yo 2. It allows for perfect axle centering, never has to be tuned and creates a more stable and balanced yo-yo 3. It allows for a wide variety of mods (including the FHZ hubstack kit) 4. Easy to take apart and put back together with no parts "explosion" This is the first yo-yo on the market (that we know of) to be soda blasted and clear anodized which gives it a smooth and clean look as well as better grinds! Grinding is also improved by the "Projection Profile" which are the grooves on the inner surface. Pictures just don't do this finish justice! The overall profile is designed to have a heavy rim weight and be comfortable to hold. One Drop spent months in design and testing refining the profile and weight ratios.
