As we speak, I am fondling and flipping a Benchmade 551SBK that I bought probably eight years ago, carried for a year or two, then tossed in a junk drawer after finding a thinner knife that fit my needs better. I always thought it was a little fat for pocket carry, so I put it away and figured I'd use it for a knife around the house.
Today, I dug it out and took it to a local shop to get tuned up and sharpened, and it has found it's way back into my rotation for a weekend fishing and outdoors knife which can take a bit of a beating instead of my other knifes. While I no longer like partially serrated blades, it did a great job back when I used it as an EDC and I've breathed new life into it again. Overall, a well built, solid lockup knife that uses the beloved AXIS lock. And I agree; prices on these knives are just ridiculous and I've since moved on and favor other brands for the same price. Don't beat yourself up over this purchase, and use it as a learning point to figure out if you like serrations or not.
