Andrew;
here is an article supporting your idea.
It is from the Home Shop Machinist, 2002 Sept.-Oct. Issue page 36
titled:
"Make Your Own Socket Head Fasteners with the Brinkerhoff Rotary Broach".

It is an interesting approach and does use a hex key that is sharpened and hardened. Unfortunately the magazine does not provide online copies of the article. Enjoy Larry Upjohn.
