As i see it ( point of view of a 25 year old graduating structural engineer), this is a piercing weapon and not a slashing weapon. You can model the piercing effect with a localized force on the tip of the blade, directed as the blade itself. This means that, due to secondary effects of point loads, it will bend. And…

Those holes create an amplification of the stresses in the vicinity of the hole. Having studied fracture mechanics and fracture propagation, you should have an amplification factor of around 3. The problem with those holes is, as already stated, that they are in the most stressed part of the blade, both in bending and…

I was thinking the same thing. If i try to chat with amazon, i need to provide my password.
