The wood handled knife has a six and one half inch blade. When forging down a piece of steel, often the shape of the blade just comes forth. The ones with marbles are basically letter openers. Been smithing semi seroiusly for a good 15 years. Hope to move my hot stuff from the shop to another building here, this summer. Makes me nervous to have a fire going, in a building with wood shavings, tires, oil cans, etc. Like to get some more elbow room. I live on an old farm site, so spreading out is no problem.
