I always think of my German grandad's handmade "slaw grater" hanging on a hook at the top of the basement stairs. You just never knew when there might be a cabbage that needed brining into kraut, so that grater had to be handy!
He made the wooden part of the grater, but I guess you could buy blades for them back then--but I'm certain he sharpened it himself. The crocks they used to brine the kraut are certainly collectors' items now.
I have his old meat grinder for sausages and such. Those hand-cranked ones haven't changed a bit in over a century.
My mother had one of those old meat grinders...I used to have to turn if for her...
She would make her own hash...from leftover roast.
Lakeland's in Britain still sell those.
Lucky you to have such a piece of memorabilia not only of an art gone by but...your grandfathers to boot. That's wonderful. I would display it with pride in my kitchen for all to see. Would be nice for when kids ask what it is. How nice a story you can tell them. Happy New Year, Friend!
