If you choose Kershaw, may I suggest the 0561 over the 0560. It's G-10 scales are dark earth (brown) as opposed to black, and I feel it's like an extra nod to Hinderer and his exclusive knives. On another note, the 0561's came out after a significant quantity of the 0560's, giving them a chance to get some of the kinks out, like improving the detent, carbonizing the lockbar, milling an small circle (yielding to a bigger one and ultimately an oval) on the lockbar (near where it joins the frame, under the pocket clip) thus reducing the pressure on the blade as the knife glides open? And there was something about switching from or to a radial... I'm not even close to an expert, but I probably watched just about every review on YouTube, some so obnoxious (we know which ones they are) it drove me to drink, and the info I gave seems like generally accepted possibilities and is no way being presented as fact beyond doubt. I love my ZT0561 and made it a point to get a late serial numbered knife for those reasons. Mine is in the 6xxx range and all I have to do now is name her! XD Happy shopping!
