The 4-part Santa Cruz Jumbo Shredder is the absolute king of herb grinders. It is a massive 100mm across, that is 4 inches in diameter to anyone who is non-metric. The sheer capacity and ability to literally shred huge amounts of your herbs in one go is simply unrivaled.
The concave diamond shaped teeth have razor sharp edges that will tear apart even the most densely packed herbs and will pull them apart leaving a finely ground but nicely fluffed up stack of herbs in the lower collector section. The base of the collector has a sifter screen in it which allows any broken trichome heads to fall through into the kief collector section in the base.
The whole thing is made of CNC-Aluminum so it will be tough enough to withstand any knocks or drops and the teeth will keep their sharp edges for years to come. Like all Santa Cruz grinders, the Jumbo comes in a choice of colors which you can select from the drop-down menu above. Grab the daddy of grinders and never need another one ever again!
