Chestnut Scorer

A few years ago I purchased a chestnut scorer. Designed like a scissor, but
one blade has a cup, the other a small knife, and when squeezed it scores
the chestnut. I gave mine to my mother, figuring I'd simply buy another.
But searching on the web I can't find anyone selling such a thing. I think
I bought mine from Sur La Table, but all they have now for chestnuts is a
roasting pan. Anyone know where I can buy one of these?

Thanks, Don <donwiss at panix.com>.
