To make things worse try the following:
Two knifes - both hands moving in opposite directions. i.e. when one goes up the other goes down.
Have the person with both in ice pick, then both in hammer grips then mix tehm one of each and see what happens. How the differences are.
If both in hammer and looking for advanced try it with some rompida (* wrist rotation so you always have the edge on the side of the blade that is moving. This should look like a scissors for the blades if they were close to each other.
