Well, I believe you have tried to make a good knife, but not for throwing. This knife will hit the target handle first within a couple of throw. The handle will be destroyed. The balance on a throwing knife should be half way between the tip and the butt. As well the point should be in the middle of the blade. Handle scales if any might be leather with rivets. It will still sometimes hit handle first. It may seem strange but these knives are most often thrown with holding the handle not the tip. A knife made from 3/16" stock about 14" - 15" long can work very well. Frank
