DIY forged tomahawk

No sketch, no prep. Practicing hammer skills using an old high carbon railway spike for base material. I should have left more "meat" on the blade area. My main mistake here, is I pretty much worked it with the hammer, to its final dimensions. This is bad. It makes it difficult for me to do final heat treatment, and using files/stones to fine tune the final blade geometry.
