I had a can of whole freeze dried Krill, and was tired of breaking it by hand. I was in Pigeon Forge browsing one of those cheap knife, in appropriate bumper sticker, ...ahem... tobacco accessory shops. I noticed the little Yo-Yo shaped grinders and decided that they would be perfect for the Krill. With a nod and a wink, the cashier told me to have a good time. I attempted to protest and explain, but he was not buying it.
In the end, It worked perfectly. Now it is stored with my hypodermic needle for injecting aptasia, and my straight razors for scraping glass.
