My grail knife is always "the next one", whichever one that happens to be. So of course I don't own it yet.
Over the years (What?!? It's decades already?

How did that happen?) I've chased & owned some knives from makers I admire & respect immensely for artistic vision, knives of utilitarian durability, or historic significance. (Rinaldi, Randall, Rader, Raymond Richard, Siegle, Wheeler, Bussekin, Murray Carter & apprentices, BK&T, Robert Erickson, Wegner, Livesay, Watanabe, Stegner, Okuden, various other Japanese makers, Spyderco, Benchmade, Mac, Vic & SAKs, and I'm sure lots of others I've forgotten, plus the unmarked wares of unnamed craftsmen that "sparked joy"™ every time I used them.) Now a Lochsa, that's one I'll likely not acquire in spite of my admiration for the design, since I have trouble reconciling the higher price with a likely small potential increment in function over knives that cost a small fraction of the price.
I enjoyed past grails while they were in my possession, then sold most of them to fund the next purchases. These days my focus is mostly on kitchen knives, or at least knives that could be used in dinner prep as I try to move away from knives that are "too good to use". But most of my current collection are not all that rare, so are relatively easy to acquire and don't remain grails long enough to count as such.
That said, I do have a Magnacut David Mary Boomerang in the pipeline & the Badger Scout in the picture from him in the mail. So for the moment those are my grails.
