New range of grinders look awesome and this 50mm version sits in the middle of the range. They are constructed from CNC'd Aluminum so you know they will stand up to pretty much any abuse and they have given it diamond shaped teeth so it cuts cleanly and efficiently even with really dense material. There is a sifter screen in the base for catching your pollen and they give you and little plastic pollen scraper to scoop it out. They have also fitted magnets in the top and bottom halves of the grinder section to keep the whole thing together when you aren't using it.
