This I squished down on end and spread it out until it was about 1/4 inch thick. I punched a hole roughly in the center.

Then I added a slot off center and started to open it up until I could start putting some hawk/axe drifts into it.

Once I got a decent sized drift into it, I started to neck down the sides around the drift.

Now I started to spread the lobes out with a cross peen and extending the bevels out.

This is after HT and hand sanding to 220. This will be a little Ulu. I may just keep this as an herb chopper or maybe even a head knife for my leather work.

Late to the party buy 2 years but this sounded like fun. so i never got to geometry in high school but I think if I take this 3/4ths inch round of 'I found it in my garage steel' at 1 1/4th inches it should give me roughly 1 cubic inch of steel. And i am going to make a scalpel. The one shown is I think 4600 KC steel with Hack saw blades i made earlier this year from an old piece of leftover Canister steel i made a few years back...when i was learning to set the canister by hand

I live in an old railroad/factory town the garage has been there for over 100 years, and it was originally some kind of massive industrial tool made of 2 kinds of steel that got salvaged and made into an ice breaker chipper...I have used it to make some things, but ya i dont know what it is. i will cut it tomorrow as i have been awake way to long.
