Improve Consistency - With this WDT tool, you can break up clumps by stirring the grounds, distributing them more evenly before tamping. Thus, resulting in more even extraction and reduced channeling. Easy to Use - There are a total of 9 holes, and you can easily replace the needles by loosening the ABS center shaft. The base of the holder has a pad to protect the tabletop surface. Ergonomic Design - Inspired by the V4 tamper handle design, based on V2. Comfortable to hold and perfectly matches other Normcore accessories. Durable and Easy to Clean - The sturdy handle is made of anodized aluminum CNC. The spring wires are non-stick, easy to clean, and made using premium 304 stainless steel that is rust-resistant.
