My late wife was a skater, and a far better one than I was, but she is gone now. I have her tool, or whatever you want to call it, for scribing circles in the ice. It is in great shape and comes in a vinyl carrying case. Can some one tell me what it is worth? Also, where would be the best place to run an ad to sell it? If I can't sell it for a reasonable price, can someone suggest a group I can donate it to.
