Thanks for the mail, and yes I did forsee that I most likely would miss some important pieces of information, so let me try again.
Weight 250 g.
Length of blade 90 cm, impact 60 cm down the blade.
Length of sliding 60 cm. Starting 15 cm from the hilt.
Speed of impact 40 km/h
We must assume, not to make it too complicated, that the blade is straight, that the weight is in one piece sliding in the middle of the blade (double edged), and that the friction at any time is close to nil, although you are right that while fighting blod would slow the slider down.
I will comment on what you write about the beads, steel balls later on this thread.
