I picked up this lot the other day and was looking for some ideas on how to refinish one of them. The handle in specific is the white and blue on the right side. The top is blue rubber and the bottom is a white fine type of stone. The previous owner said that it use to have plastic on the bottom. I would love to keep the handle even if its like it is but it seems the white stone can kind of chip or rub off easily. Any one reccomend anything to protect it or had handles like this.
