This 1886 design is so perfect that it is still being made today, and has become the standard meat grinder. (This one has the 1886 patent date on it.) Though this is the hand crank version, there is a pulley available that can be used to hook this up to an electric motor. I happened to see one in use during a cooking show set in Cambodia, where an entire sausage factory was being powered by just one of these grinders.
One of the benefits of this being the standard is that one can be had on the cheap, and I paid fifteen bucks for this one. Someone had put the cutter on backwards, which had made it non-functional. I re-ground and sharpened it, and put it back on the right way. There are also innumerable attachments.
Here’s a vintage grinder plate, a used one, and a new one. The one with the large holes is used with the somewhat deadly looking sausage stuffers, which allows anyone to go crazy making sausage. That’s why I have intestines in my fridge, aka sausage casings.
There’s an even larger version of this, the #33, which is handy if your name is Dr. Lecter.
