Little Manmays,
That's a nice looking spike knife you made there. Spikes are great for practice, and provide a good platform for developing shapes and design as you have a common, limited, chunk of steel each time you begin. I stopped making anything out of rr spikes when I finally made something I really liked, but it wouldn't hold an edge. Think about using some old car spring (52100) or another high carbon steel next time, and ask your brother to teach you how to properly heat treat it. The root of any knife is its edge, and it's ability to hold it, next is toughness and the ability to hold up under the task it's designed for, and last (but not least) is its ergonomics and lines. As HoJ said don't sweat the the mistakes. Knife making is a process of recovery!
