true enough. From a ninpo perspective, one almsot looks at it from a physics-like paradigm. If it has the potential to do work, then it has the potential to do damage, even if it's at a psychological level.
So, you'll hear us say " all weapons are the same."
Obviously this isnt true from a scientific viewpoint, but in the way that we move, it is.
We have a concept called "kakushi buki."
That means "hidden weapons." It is very important. A weapon that is not seen cannot be defended against. If you have a small weapon, like a pencil, this give the pencil magnified capabilities. IF you have a 22 inch Ganga Ram, that gives the Ganga Ram magnified capabilities.
Imagine that.
Hiding weapons magnifies their power.
Thus, we dont really have a preference in the size of the wepon, its really just how you use it. Having said that, some sizes and shapes do lend themselves well to being hidden, and that expresses itself from time to time.
