I will attempt to beat a dead horse with another glowing review of this knife. Such close attention to detail with this piece. Awesome walk and talk with the most satisfying clinks when opening and closing. The fit and finish are outstanding. Pictures don’t do it justice. The rounded mirror finish back spring is outstanding. Zero blade play or blade rap, and no proud tip. The only nitpicky flaw I could find was some minor gaps between the blade end pin and center pin.
Really perfect balance of traditional and modern, feels like its from the future and past at the same time. If you’re on the fence, go for it. You will not regret it. The price allows these to be used and loved. I imagine when these are gone the will be highly sought after on secondary markets.

Great quality, no surprise considering prior reviews. Can’t say enough about the quality. Pull is perfect and so is the fit and finish. Beautifully done!

Not going to rehash what’s been said by others – I’ll just say I confirm their positive comments. The one thing I’ll add is that the natural micarta appears to be a light color in the pics and appears such in person. However, when oiling this knife I found the micarta darkens considerably and looks, in my opinion, much better. So that was a pleasant surprise. I don’t have much experience with micarta, so, maybe this was to be expected.

Best modern traditional out there. Mirror polished back spring is luxurious. Excellent action.

I’ve bought a few knives from CK, particularly their exclusives, and I’ve not been let down yet. They are the best modern traditionals available at this price point. Period. If you’re on the fence, just buy one. You won’t regret it. Thanks.

This swayback is a great knife. It is an easy to carry, well built pocket knife with a great design that came sharp out of the box.

Another very nice CK Italian collaboration. Everything about the fit and finish is great. Pull is good and tight, just the way I like them. The blade is sharp, some other companies can’t get this. I want them sharp new, this Viper Swayback and my recent Lion Steel both came sharp. The backspring on this knife looks tough, no sharp edges around the frame either. The micarta is very well done.
Thanks CK for another nice modern slipjoint.
