I've been practicing with just about any item I can find. I didn't take a picture of the spike before I started, but I'm sure you all know what they look like. This spike I found many years ago with my metal detector. I'm planning on using the area under the head for a bottle opener. It's simple just grind in a groove under the lip. I got that idea in Montana this winter at a bar I went to. I still have some work left to do with it. Thanks for looking!
