It's constructed very simply, rather like a paring knife. There's no ergonomically designed handle or swiveling blade. There's one blade, with a pointed tip that comes in handy for digging out potato eyes. There is a one-sided peeler cut into the blade.
This peeler fits snugly in the hand, and it lets you keep a close hold on whatever you're peeling. It's rather different from most peelers I have used, but I really liked the way it felt. I use it often now for apples, pears, and potatoes.
These traditional peelers can be found in the USA at Conran.
