Brute de Forge one-piece blade made from automotive coil spring.
All hand tools and coal forge (no power tools at all).
Design concept was something between a seax and a santoku shape. That took a pretty aggressive pre-bend to end up with a straight edge.
I was trying to get more of an aggressive step down to the blade to keep the hand from sliding forward on a thrust, but this is the best I could get.
Steps: Forged, annealed, fine shaping and edging with files, oil quenched, tempered, sharpened (it will remove arm hair nicely).
I know there are some major hammer marks that would be a challenge to remove if I were going for a clean finish, but they work okay with the brute de forge.
