My first CRK was a Large Classic Sebbie. I'm well experienced with folders; I own a Benchmade, a SOG, a Spydie, a couple of Kershaws, a handful of CRKTs, a wee little Gerber, and a a few others.
I work on my feet, so I'm always finding an excuse to use a knife. The Sebbie is my favorite. Every knife I've owned, from the Gerber to the Benchmade, has developed a bit of wobble with extended use, and no amount of pivot adjustment will fix it forever - not without making it impossible to open. The Sebbie is the exception; it doesn't wobble one little bit. I trust it'll be the same when I give it to my grandkids - what a moment that'll be.
I've worked with a number of high-end steels in my few days. The Spydie uses VG-10, which served me well during my days in landscaping. The Benchmade uses D2; a steel they've been making knives with since the turn of the century. The Sandvick 13C26 is impressing me as well; in the three-odd months I've owned my Leek, I've yet to have to sharpen it once. It still shaves when I ask it to.
Now I know this is all subject to various degrees of personal experience and fluctuating quality control, but the S30V in the Sebbie's blade has been so close to this high performance that I can scarcely tell them apart. Combined with the ease of sharpening, the Seb is more than comparable on terms of performance.
All of this, plus the infinite smoothness and the perfect weight and grip of the Seb is what makes it stand out as my favourite. I could laud it further, but I don't want to seem any more like some kind of fanatic.
This knife is good the way a mastercrafted film is good; every time I see/use it, I feel something great, and maybe something new.
