As I mentioned in another thread, I just got a new LE FBM! Wow! (pics to come!)

My question...What is the purpose of the waviness along the spine? It looks as though it would perhaps aid in batoning or something. It looks cool, that is for sure.
 
I think the first hump is useful as a thumbrest when choking up on the blade, and the middle "valley" could be a useful batonning spot. Or it could have something to do with improving the center of gravity or moment of inertia when chopping or some such nerdism. Anyway, what mistress doesn't have humps in all the right places?:D

I think you answered your own question......:p
 
Not every single line on a blade has to be functional. My feeling is that the humps on the Mistress, and on the Scrofa, are purely aesthetic. They don't detract from function, and they look pretty cool, so why not?

Also, they aid in zombie deanimation, which is important.
 
I believe Jerry has described it as "scalloping" of the blade. In the last Knoboganza there was an awesome custom shop AD with scalloping. They just look badass.
 
Just another quality example of form following function :thumbup: :thumbup: :D
 
I have had to explain this before. The high points on the spine provide dampening mass. They are separated by half the distance between the standing vibration nodes produced at the resonant frequency of the blade. The purpose is to minimize the shock to the hand produced when the blade is used for heavy chopping. It is intended to produce an effect kinda like hitting a baseball on a wooden bat's "sweet spot," a sensation like no other in sports. This is one of the reasons the FBM chops so well.

The vibration dampening is not needed on smaller blades used primarily for slicing, but sometimes the shop puts them on there for looks.

OP could explain this further.;)
