Hobsons choice...from Mike...

HERE IS THE INTERESTING PART
I Spark Tested the Blades.
They sparked Fine but had short Spark Tails.
Hmmm........Not Hard Enough
Remember--At this point We were Still Assuming they were 1095.
Abby Boxed them up and we Shipped them to Our Trusted Heat Treater.
I asked them to call when they arrived.
Two Days later I got the Call and told them to Heat Treat one of them as if it was 1095.
The next day--they called and Said.........40 Rockwell
I asked them to Rockwell Test one that they did not touch.
I waited on the phone and he came back with.......40 rockwell
That told me a lot.
First---Somebody else also thought that they were 1095. hence--The Blades looked Heat Treated.
Second--They needed to go Hotter in the Initial Hardening Stage. They were not 1095.
Third--The Blades were alloyed and were not a Simple Steel --like 1095.
The logical next Step was to Develop a Profile closer to an alloy Steel.
I gave them New Temperatures for Heat--Quench and Temper.
They said that they would proceed with 5 and then call me Back.
I got the Call the Next Morning and the word was--57-58 rockwell
I told him to run all of the Blades using that profile.
He said that he had to put something on the paperwork.
He asked What this profile was called and what was the Steel?
I told Him--"Hobson's Choice"
