Cutting through hardened steel with muscle power

[Lightspeed5]

Would it be possible for a reasonably built human to abrade through hardened steel if he had a blade made out of diamond? Or is human muscle power insufficient to break the chemical bonds?

Sure - it's done all the time.

My Morse 8% cobalt hacksaw blade goes thru 4130 chrome-moly steel like a knife through hot butter.

As stated above, with the appropriate tool (a good hacksaw), it isn't all that difficult.
