You use it to handle logs. The hook swings. This was late in the auction, so the silhouette effect was produced by the low sun. One of my favorite things about the auction was the fact that the auctioneer knew what almost everything was, and what it was worth, when it was held up. He added little comments about condition and usefulness also. It was educational; a year or two of attending these events would add a lot to my store of information. It was one of the last things I did with my 19 year old grandson before he went away to do religious work. Knowing he would leave mingled with my pleasure in this country auction in a strange way.
