Have you ever heard of centripetal force? Did you take high school physics? A claymore weighs about, 2.5 kg. The radius is about 0.1 meters. You swing it pretty much as fast as you can, let's say 30 miles per hour, which is about 15 meters per second.
F=m*((v squared)/r)
F= 2.5kg*((15m/s squared)/0.1m
F=2.5kg*((225m/s)/0.1m)
F=2.5kg*(2250meters squared/s)
F=5625 kg*meters squared/second
F=5625 N (newtons)
That's over 1000 pounds of force. So yes, that 5-6 pounds is quite a lot. Mr. Catchings was right, I do use physics in my everyday life. You still you can dual wield claymores?
It is possible to 1 hand wield a claymore, but it is pointless; less control, less strength, less balance. It is a scare tactic if you're trying to scare a 4 year old. Dual wielding...past pointless. Past ridiculous. Don't say we haven't gotten any good points, you obviously haven't read any of them.
