On the surface, I have a pretty monochromatic knife collection. For the most part, they're one hand openers with 3"-3.5" blades, black handles, uncoated + plain-edge blades, no recurves, no tantos, no double-edged blades, no wharncliffes, and slightly on the beefier side. There are a couple of SAKs, an Opinel, and an Orange Manix to add a little colour, but otherwise each of my knives look the same as the next.
I do have a decently wide variety of brands, steels, mechanisms, and such, I guess. Spyderco, Kershaw, Benchmade, Victorinox, Cold Steel, Leatherman, Gerber, and many more assorted makers. I guess I do play favourites a bit in the sense that I've had good experiences with Kershaw and Spyderco, so I'm more likely to buy from them in the future, but I'm still open to all kinds of different brands.
