i dont train, just have some practice over the years. and i have to say i am not a geek in this, just a fan.

one of my best friends trains there for now 18(?) years. i do some bokken-practise and cutting-tests with him from time to time (i loose every single fight since first time^^). and yes, we tried a half pig years ago... frightening what these things do to flesh&bones that easy, i have the video somewhere around, have to search.
blade and habaki on your pic looks like a john-lee-blade (dont hurt me if i am wrong

). chinese/hongkong, "cheap" but very good blades, i have an aikuchi-tanto made by them (

and yes, you are right, ninjablade would be totally straight, my fault, but AJs model is so ... light. definitely too peaky, it would break.
katana is a very heavy weapon on your wrists, first cut hurts so bad everytime if you are not in training, and you come easily through wood/bamboo even with a slighty rounded top, you just have not to stab but to "cut upwards". as i say to him everytime, if you would use this without technique, a katana is a really horrible blade...because its an axe^^ roman gladius is much better to handle.
is this thread-hijacking? but nice to see you around here, wolf.
i follow your blog and cant wait to see something of your udk-stuff here (had a look and the engine doesnt seem as complicated as thought?).
