Well, I annealed this blade and forged a bit more of an upwards curve in it this time. Re-filed and clay coated and hardened and i'm much happier with the results. Here are some pictures of this 2nd attempt. I've only polished it with the first stone, 250 grit, but then did a quick hot vinegar etch to get a good look at the hamon. I like the way this one turned out. I'll post more pics of polishing on the higher grit stones when i get to them. I've also got a video of the quenching of this blade that i have to capture and edit and post so that's coming too.
The hamon did go a little higher in the middle of the blade than i wanted, not sure if i put the clay on higher or thinner there or if the water got under the clay during the quench. It's still a keeper though...
1 - The forged blade filed to shape.
2 - Clay coating. Clay was applied, then a wire wrap, then a thinner layer of clay to cover the wire.
3 - After the quench.
4 - first polish with 250grit stone (closeup) hamon slightly showing.
