Naginata Anyone???

Thinking about the mechanics . . . if the sweet spot of the blade is say 5-6" off the bolster, and you have a 16" tang, that means you have some 21-22" from the end of the tang to the point of percussion. That's a pretty dern long moment arm, and all that stress will be applied right at the end of the tang, where the shaft is split and (I'd reckon) most likely to break. With exposed-tang construction, I wonder if it wouldn't be more durable with a SHORTER tang and maybe two pins?

Somebody with more physics brains than me could probably figure this out without having to resort to testing.

BTW, the bushaxe I was talking about before had about a 4-5" tang and two "pins," but the end of the shaft was broadened so there was more wood there, too. And it could definitely take a hit.
 
I havent thought about it that way. I will consult some of my friends here that are majoring in physics to see what they say.

As a matter of fact I should tell them what I want and let them have a go at it and see what they come up with. They are nerds... but nerds are used to being picked on and are viscious. This might be interesting.
 
SamuraiDave, you might want to tell them to design one with the traditional attributes but with modern enhancements and to be made under primitive smithing conditions. Then tell them the jocks said it can't be done...

I guarantee that they will come up with something...
