This product is no longer available, but don't go just yet.

Kershaw 1985ST RJ I, Assisted, G10 Handle, Satin Finish Tanto, ComboEdge. Designed by RJ Martin, the RJ I's blade design and grind provides a moderately curved belly with plenty of slicing power, plus a flat-ground tanto tip that's significantly thicker than comparable tantos. The result is an super-strong tip that takes on the toughest piercing tasks with no fear. The RJ I features 3-D machined G-10 handles with a stainless-steel liner lock on the back only, making it a lightweight carry. It opens easily with SpeedSafe® assisted opening with a handy flipper or thumbstud and carries tip-up or tip-down for right-handers and tip-up for lefties. Partial blade serration adds cutting power for tough jobs.

Great knife that holds its edge practically forever! After being used daily for 8 months or so & not even needing to be stropped, I used it to cut a desk chair mat in half (one of the plastic ones for carpeted floors that are about 1/4" thick), dock the excess off of zip ties (not always with the serrated part of the blade), and my uncle used it to cut through wiring & Romex cable a few times, before I had to sharpen it!
There are only two issues with this knife: 1. It doesn't come in a plain edge variant, which I would prefer. And 2. The torsion bar on it kinda sucks. I've had to had 3 of them replaced. This needs clarification. I've had the torsion bar replaced once, for three different RJ I knives. I like to open my folding knives (I like the "Snick" sound that they make) a once or twice a day, even if I don't use the knife. It took about a year for the first torsion bar to fail, as the knife was being opened of course. Being that my number one rule is "Never go anywhere without a knife," I did not look forward to sending it to Kershaw for warranty repair. Fortunately I had the foresight to buy a second one, and a backup for my backup. I did this because without fail, every time I find a product that I just love, it tends to get discontinued by the manufacturer. This is one of those, though I'm not buying a fourth. My wife says I already have enough. She's right, as I've since replaced the RJI with an HK knife as my EDC.
