I didn't bother to anneal the hacksaw blade first. I was careful to not overheat it while grinding the profile and I used a dremell tool to grind out the two holes for the handle. I just checked the edge and a file still skates over the steel so my grind didn't get to hot. It was a fun project though and I'll be ordering some O1 plate to have another go.
