I have and love a 55, but it may be worth pointing out that, as is often the case on Bucks, the kick/tang is quite large. From the plunge to the tip, the 55 is not a whole lot longer than the same dimensions on a peanut. Since you mentioned wanting to cut food, it bears mentioning.
The blade shape does have a long, gentle belly going into a needle-like tip -- it will give most wharncliffes a run for their money. It pierces beautifully (I had a bandaid on my thumb last week to prove it) but strikes me as likely fragile for piercing heavier materials. The Buck 503 is the same size, but with a thicker drop point, FWIW.
The copperlock, mentioned above, has a more robust point and a good bit more blade, but is only available in TruSharp at the moment, which I would put behind both Buck's 420 and Case's CV. They are a beautiful thing though. The fellow who designed it had a good eye.
Have you considered a Case Sodbuster Jr? They're single blade, come in CV, have a stouter blade for general use, a similar frame-shape to the Bucks, and they're a bit cheaper than the slimline (but with a thicker handle than any of the above.) It might make a good middleground, and a cheap way to conquer your slippiephobia
I ain't makin' your life any easier, am I?
