The M1 was One Drop's second yo-yo, first released in the December of 2008. It is essentially a Project with a slimmer shape and rims, no Projection Profile grooves, and instead of the nuts held in place by small pieces of rubber, it has press fit nuts. The M1's name stands for metal for everyone. One Drop did this by pricing the M1 at around $60. The original release of the yo-yo featured a recess for .555-sized response pads, and the later version uses silicone flow grooves similar to a YoYoJam yo-yo.
