What a difficult question to answer...

My original Grail, which remains my favorite Busse (or Kin) knife....is the SS4. I went on a binge...and ended up with 4 of them. Gave one to my father (now his most carried knife), sold another to a good guy right here on the forums...then decided I only needed one (which isn't going anywhere, unless I go broke in the near future) and sold another.

I really like the 4" knives. I think an SS4 LE would probably get me buzzing pretty hard. Although, that doesn't exist so it's hard to call that a Grail of any sort. I almost jumped on a BogDog that was up last week on the exchange...but showed great willpower not doing so (had to have a drink or two to sustain).

Right now...i'm infatuated with trying out a few fiddleback's (i blame RN and Jrod). Those handles are just soooo nice, and I love the hard working nature of them.

I think if I could have one bussekin, where price did not matter, nor did function....as in an ideal world where price nor utility concerned me....I'd love to hang a Satin Busse Ruck on my wall (black paper handles). So, maybe that's my grail. But, that won't happen unless I strike the lotto, because I am horrible about sending knives on their way that have no use to me (in a logical sense).
