What a fantastically fearsome sword, looks impractical to me, but to have that un-sheathed in a threatening manner would certainly frighten the hell out of me
As to the 'blade catcher' well IMHO, irrespective of the strength of the blade, the skill and accuracy required to trap your opponants blade would be extraordinary. If a swordsman's skill was that good, he certainly would not need to trap your blade....a bit like fighting Goliath ......without the sling shot.
But that 'saw' edged blade 'slashed' across the chest, gives new meaning to open heart surgery
I REALLY LIKE IT
