These are functional EDC bottle openers made of 11 gauge, hot rolled mild steel. I designed them, cut them using a waterjet, and ground the bevel using belt grinder. I also smoothed the edges and removed some of the scale using a wire brush. You are getting an item that's very close to the one shown in pictures. The beveled end is a light duty prybar. I carry one of these on my keychain and use the pry bar end to open packages. Dimensions: 2.5 inches long, 1.25 inches wide. The patina of hot rolled steel will somewhat protect the metal from rust; however, this is not stainless steel.
