I must admit I never really gave much thought to the respective merits of the different types of Do-dai now available. Of course I am not referring to the hundred shades of colour or to the infinite possibilities for Mune decoration. I mean what a Do is really made of.
In my Kendo career I always took for granted the most widespread types: the Fiber Do and the Take Do. It took me to pass rokudan to finally have a Take Do made for me, but I guess I have been a little conservative in my approach.
Take Do are easy to purchase now and they retain the same beauty, even when they wear a bit. Due to the fact that they are not made of one piece, tiny cracks can appear on the INSIDE of the Do-dai: a bit of wabi-sabi aesthetic appreciation built into our traditionally-made armour. Old Take Do, even a bit battered, acquire a special beauty, just as a piece of antique would do.
Fiber Do have always been the practical, unassuming alternative - cheaper, practically immortal, lighter than the Take Do, the humble Fiber Do seemed to be the winner of the competition hands down. Now a new kid is in town and it took most kenshi by storm: the Yamato 50 Pieces Do.
Plastic still: but so cleverly shaped that it cannot be distinguished - if not touched and listened carefully to - from a traditional Take Do.
I wrote "listened to": I mean that a gentle knock on the inside can tell you the truth about it. If someone wonders whether Yamato Do, Fiber Do and Take Do sound differently when hit during a shiai, I say: hold your peace: they don`t.
I am a trained sommelier and someone asks me from time to time if I can distinguish a vintage from another in a blind tasting - believe, no one can. As Kendo referee, believe me just the same: no one will deny a good Do Ippon because of the SOUND of the Do: first of all because we have to use our eyes to evaluate a Do-uchi, but also because there is NO AUDIBLE DIFFERENCE between different types of Do when hit.
Having answered this vital question (that someone actually asked), let`s go back to the real difference: weight. Take Do are heavier - but then the choice is really up to you: it is tradition vs. innovation.
And no one, except yourself, will be able to tell which Do finally won its way to your bogu bag.
