What an astonishingly priced piece of tat ! I can see no practical use for the thing whatsoever. I wouldn't even use it as a cheese knife for fear of having the thing snap due to that ridiculous hole through both blade and ricasso. As for the edge... Hell, I can knap flints to a neater edge than that, and they'd probably be sharper AND stronger.
Someone (bless'em), somewhere, will buy the thing and be chuffed to bits with it (until they use it and break it, I guess) but I think I can just about manage to resist the urge to put my own hand in my pocket for the time being
