That is excellent for a first try!

The blade was pretty close to .010 for most of its length it was around .012 near the toe.

I measured using my dial calipers today since they have a smaller footprint for measuring. I found a thin area running perpendicular to the edge .005 about 1” from the heel since I have a 1” wide contact wheel I am going to assume that I was rocking the blade and digging in the side of the wheel.. This does not look like cause of the problem though. Maybe I ground too thin, maybe some type of stress, maybe the razor gnomes are out to get me.

I am giving up on this one. It was a good learning experience.

I started on a frame back today after work.

I should have just popped it in the forge and walked away for three or four minutes for each heat, but I was pulling it out after less than a minute and whaling on it. Wore myself out pretty good.

Ah but the nice thing about working bigger pieces is that they don't loose their heat so quick. so you can work them for longer.

I might not have any blade smithing experiance, but I started doing blacksmithing for fun at 13(probably could have earlier as my parents age limit was I needed to be able to pick the anvil up myself, and I got real big real quick)
