I have two of "The Original Greek Pepper Mill" - it's an 8" tall copper thing. It's been amazing. Why do I have two of them, you ask? I kept my mom's after she passed; it was probably 30 years old already.

If you want to grind a ton of pepper with fine grind control, you could also use one of the modern generations of manual coffee grinders, like the MHW-3Bomber Blade R3 or the cheaper TIMEMORE knockoff. They have excellent and fast and precise grind mechanisms. I'm not sure about the MHW but the timemore will stand alone with the bottom of so you can use it like you'd use a coffee grinder, or attach the grinds cup if you want to crank out a lot.

(I'm using an older, cheaper manual coffee grinder as my sichuan peppercorn grinder and it's solid for that but I do prefer the greek mill from an aesthetic perspective -- and it's so dang solid.)
