My philosophy has been,
since I had a decent block of well-handling western knives of medium steel quality (X40 Cr 13, Kuppels Professional Gourmet),
to take my time looking for 3-piece-set (yanagi, usuba, deba) of great and puristic Japanese knives to last a lifetime, and hence not worry too much about the expense...
Japanesechefsknives was my favorite address (it didn't use to be so easy to find original Japanese sites offering English)
and I fell for the Masamoto Honkasumi Sashimi knife for my weekly sushi duty,
and a Kobayashi suminagashi usuba as a present to my girlfriend, meant for fine vegetable work, but actually most awesome as the sharpest knife we've ever had in terms of free-floating paper-cutting test etc.
the Masamoto, which is used much more often, I've not been able to keep as sharp as out-of-the-box, however lovingly I run it up and down my Japanes waterstones - I dream of a visiting Japanese grinding expert to get it back some of the basic sharpness only they know how to give
as for the deba, my purist orientation made me go for the 24th generation "Masamune", if that means anything to anybody

that, too, is used on a weekly basis at least, for its proper task of cutting down whole fish, but also for occasional carrot- and herb-cutting etc.
now I don't really mean to go beyond that holy trinity of japknives, though I know I should have two dozen of them for all the different tasks, this is the basic set for Eastern purposes, and I've got my set of 5 of the usual for the Western-style cooking prep...
I've got to say, Hattori and all the compromise versions don't really appeal to me, not to mention the affordability...
but there's one knife I still want as the perfect compromise or rather fusion of the two worlds, the
Kershaw (i.e. affordable)
of Hawaian (i.e. best of both worlds)
Ken Onion's (i.e. work of genius and unsurpassable style)
Chef's Knife, (i.e. good for most tasks, and I'm boss in my kitchen
That's also the fusion of legend (since I idolize Ken Onion)
and pragmatism (VG-10 ultra-sharpness, yet you can leave it a bit before cleansing).
