Have not forged in a while and it felt great today. These are about four inches long and are perfect for chip bags. In the future I will refine the design and produce some bigger ones for dog food and charcoal sized bags. These will be a production staple like the bottle openers. The " Spring " is due to a dark blue temper.Tried melting some of my Williamsburg Wax Medium to finish these with and I like the result, wax medium is pure beeswax and linseed oil so perfect for non food items.
