I'm not a huge fan of the CPK designs. I find that they look a bit to 'artsy' for my taste
I prefer the no nonsense look of the SK
When it comes to matrials, fit and finish and function both companies are excellent
In the hand, the CPK FK doesn't feel artsy at all *there's nothing there that shouldn't be. To me, artsy denotes unnecessary ornamentation that gets in the way of function, but the FK is an exceedingly neutral feeling knife, IMHO.
Realistically, the 4.7 and CPK have more in common than not. I'd take either one to do the same types of work, I think. For me, they're functionally redundant, and I'd be hard-pressed to assert which one I like better. Slight edge to my CPK, probably, just on account of it being D3V while my 4.7 is CruForge. The cruforge gets insaaaanely sharp, but I'm a sucker for an uncoated blade, and I've hung up my FK wet in the past couple of months, a few times, and it hasn't rusted at all, so splitting hairs, that blend of toughness and stainlessness is cool.
Anyways, I'm equally happy taking either one out to the woods with me. They're both great in the hand, and functional, for the things I use a midsized knife for.
Really, it's boiling down to carry, for me: I've got the stock kydex clip on the S!K, and a drop-loop on the CPK, so whichever of those I want to use dictates what I grab on the way out.
I'd almost like to see someone build the knife that is in the middle of the "ven diagram" of those two knives. Mostly GSO handle, mostly FK blade!
That'd be something to covet, for sure.
