Crucial

From the YoYo Wiki:

“Born Crucial (or just Crucial) is owned by Paul Yath and the manufacturer one of the first Delrin yo-yos, the Milk. The company’s second release the Milk 2% was released in May 2008 with a run of over 250 yo-yos. It is the same shape as the Milk, but it has more rim weight due to the fact of it’s smaller SPR system and A-bearing, this in turn makes for a more stable version of the Milk. The name of the company used to be Born Crucial but now it is simply Crucial.”
