That all makes sense, and i had no idea the CS Bokken was a bad as everyone is saying. i based my opinion upon the smasher bat, which although overly heavy, is also really, reallly durable. My personal bokken is ash, (I'm fairly certain) and while I've never intentionally hit anything truly solid with it, it's performed admirably for the decade or so I've owned it. It's likely Bearcut will see that the CS bokken is not up to par, and get a wooden one, after all, they aren't massively expensive. As to the "over-cut", yup, that's a mistake I'm sure we've ALL made, and the only way to NOT make it is to train, and train on reliable and appropriate materials. I could tell you my "BudK/Shinwa/flea market combat-ready katana vs. the sapling with old jeans tied on it" story, but it's likely most beginners have one, suffice it to say what was left of the blade ground down to a decent-looking wall-hanger tanto, and thank goodness I was nimble enough (barely) to avoid the flying portion. As with any weapon, a large majority of purchasers may buy it and it becomes a "safe queen", but the ONLY way to learn, is to train. As not everyone lives near a Sword School of Renown, or Japan, sometimes the ONLY means of learnign available is the one taken by many of us, books, and now the web, and trial and error.
Side note: Thank you for the heads up on kingfisher, i have two staff-grade dowels on the way, and incredibly cheap. As I grow older it's almost as nice to create a beautiful weapon as it is to use one (almost), and these will make lovely practice Jo for my boys, after sanding and finishing. I was drooling through that entire website.
