I've had a Kershaw Talon 1421ST now for about a year...
It was my every day carry knife (in a nylon/velcro belt sheath) until I got a Sebenza. Now I use it mainly on the weekends. My "review" is...
Overall, the knife feels a little too heavy for the pocket, hence the sheath. The pocket clip is mounted too low and is nearly useless except for assisting the knife to cling in a belt sheath. (I'm afraid it's gonna slip out because so much knife is exposed to get caught on something.)
The handle is slightly recurved and very comfortable to my hand. The partially serrated blade cuts good like a knife should, and stays sharp throughout many rope, 550 cord and cardboard cuttings. (I've only sharped mine twice). The bottle opener works with the blade opened or closed - it's great for opening longnecks at parties - and doubles as the thumb stud.
My knife shows two or three minor specs of rust at the liner/scale junction (I use it around saltwater alot). The blade shows no rust.
At first, the liner only engaged the most proximal side of the blade. But, after failing the "slap the spine" test several times in a row, the liner must've deburred and now engages the middle of the blade w/ a solid "click." The lock has not failed anymore either.
I placed a lanyard on mine and like it.
Bottom line: this is a hardy knife for arduous chores. I like it, even w/ its few flaws. My father in law (a machinist) got one soon after mine and "fixed' all the creampuff stuff. (ie thinned the scales and skeletonized 'em etc) I'll keep mine like it is "Warts and all."
Later,
John
