I'm trying to get into bow making and am a poor graduate student with extra time. So, while some staves are drying I decided to make my own draw knife!

Very pleased with the results, particularly because this was my first time working any kind of hot metal! Just under 8 inches for the cutting edge. Now those bow staves have to dry...
