Let me tell you that if you buy that KIKUO HURRICANE you are talking about... your hand will be too sore to put the knife to its paces. Have you imagined what it could be to do any kind of hard work while holding that handle? It narrows at the end of it, so your hand will slip if you were to hold it there for chopping (to gain more leverage). And the general shape of the knife does not seem to put the weight forward, so chopping is out of the question. Also you stated quite a few times that you want a boombproof knife but you are thinking about buying a knife with such a pointy tip that there is no need to be an engineer to see that you won't be able to do any prying. The handle is not going to be comfortable by any means, it is not neutral at all (only one way to hold onto that handle). And last but not least, ¿have you thought about sharpening that knife?
Seriously. When all of us read your first post, we all thought you were talking about a big Busse or a similar sized/shaped knife from another makers with fancy metals. Of course with a truly determination to use it... and use it hard. But now, after the KIKOU HURRICANE suggestion... y just seems you are looking for an expensive fantasy knife. A tryly expensive fantasy knife btw... $700 (including shipping) could buy you a lot of Busse.
But, each to his own. It is your money.
