Fencers are a tough breed. We would do better in the Olympics if they started us at a decent age here, like about 4!
I have a 4 year old.
He makes me pull out his grandaddy's VMI parade sword just to hold or his great great uncle's WWI Hun sword brought back from the battlefield (along with a ruined life from being gassed)
Boys and blades (or guns)....I have a nice Stryder long knife and a Gerber Bowie....have to keep those out of his way too.
I think fencing is a wonderful sport for mind and body.
