The same body as our standard Blind Shaker™️, but this product arrives with the bottom magnet not installed to allow use with non-WW grinders with unknown/reversed polarity. Built for 58mm baskets, the Blind Shaker® redistribution tool is perfectly engineered to help baristas reduce static, decrease channeling, and increase extraction yield on every shot. The polished-smooth interior is finished with a proprietary process to resist grounds sticking, to ensure minimal brushing is needed to get all grounds where they're going.
