Some years ago, in the Cambodian market, I purchased an inexpensive ($0.59) hand cutting tool of some time. I've always assumed it was for ginger, and the other day I used it to slice ginger and it worked well, but I'd really like to know for sure.
This thing has a metal working part that's maybe 3 inches long, attached to a wooden handle about 2 in. long.
The metal working part does in fact make nice slices from a knob of ginger. In principle it's a little like the conventional swivel-bladed carrot or potato peeler. The metal part has a slot, perhaps 2 inches long, and 2 metal parts which are offset from each other by maybe 2 or 3 mm. You handle it just like a carrot peeler.
I never knew that Cambodian/SE Asian culture used that much ginger, that a special tool evolved.
Anyone have any observations about this?
