Santa Cruz Shredder Large 4 Piece Grinder

The Large 4-piece provides the most grinding capacity in the standard SCS range at 2.75 inches in diameter, which is approximately 70 percent more surface area than the 2.12-inch Medium. This is advantageous for users who grind large amounts at once, who share with multiple people, or who prefer to prepare enough herb for several sessions in a single grinding cycle. The larger kief chamber also accumulates a usable supply of pollen faster than the Medium or Small versions. The trade-off is size and portability: the Large is less pocketable than the Medium and not designed for compact everyday carry use.

The SCS tooth design uses a patented geometry developed with Siemens CAD software that gives each tooth clearances on both sides, enabling cutting in both the clockwise and counterclockwise direction. This bidirectional action shreds herb on every movement of the lid rather than only on the downstroke, requiring fewer rotations to produce a fully fluffy grind. The teeth are radiused at the base for structural strength, preventing them from dulling or developing metallic burrs that could contaminate ground herb. The result is consistent, fluffy output across thousands of grinding sessions without degradation in performance.

The medical-grade designation on Santa Cruz Shredder products refers to the manufacturing and cleanliness standards applied during production. Every SCS aluminum grinder undergoes a medical-grade ultrasonic cleansing process using high-frequency sound waves and a medical-grade cleaning solution that removes all traces of machining lubricants, metal particles, and other contaminants from the CNC manufacturing process. The anodized coating creates a food-safe, non-porous surface that does not react with herb. These standards ensure the grinder arrives free of the metallic taste or residue that can be present in unprocessed aluminum grinders.

Yes. Santa Cruz Shredder includes a guitar-pick-style triangle scraper with their 4-piece grinders. The triangle shape allows the scraper to reach the curved interior walls of the kief chamber, collecting material that a flat scraper would miss. Kief accumulates against the chamber walls and bottom surface over multiple sessions. The scraper is used to consolidate the collected kief for harvesting. For very thorough collection, some users freeze the grinder before scraping, as cold temperatures cause kief to harden slightly and release from surfaces more cleanly than at room temperature.

Santa Cruz Shredder grinders are available in multiple anodized aluminum color options, commonly including black, purple, red, green, blue, orange, gold, rasta, and gray, with additional colors introduced periodically. The anodizing process integrates color into the aluminum surface at a molecular level, making it highly resistant to scratching, peeling, or fading under normal use conditions. Specific color availability at Haze Smoke Shop varies based on current inventory. All color options perform identically, with selection being a matter of personal preference.

For routine maintenance, use a small stiff brush to clear herb particles from the teeth and screen after each session. For a deeper clean, freeze the disassembled grinder for 20 minutes to harden resin, then knock each piece gently over a clean surface to dislodge frozen material. Soak the aluminum components in isopropyl alcohol for 20 to 30 minutes, scrub with a brush, rinse thoroughly with warm water, and allow to dry completely before reassembling. Treat the stainless steel screen with care by soaking rather than pressing on the mesh. The anodized aluminum surface is alcohol-resistant and will not be damaged by isopropyl cleaning.
