The concept that skills and technique should transfer across platforms is not new or unique.
I didn't say that it was common, I just said that it's not unique.
The ability to take athletic skills like coordination, timing, speed, power, rhythm, etc., and apply them to other tools is what distinguishes good athletes from great athletes.
In the following video, I demonstrate how to take the Steel Mace Swing, and transfer the requisite skills across a wide range of loads. If you've ever swung a Steel Mace before you know how difficult this can be. If you've never swung a Mace before, let me know and I'll walk you through it so that you can experience it for yourself!
