The Packrat was released by Kershaw in 2008, and I was hesitant to get one for one simple reason: I had all the assisted openers I needed. Well, I was wrong. The Packrat gives a very comfortable handle and unique blade shape; almost like a Persian-inspired blade. It's an American-made knife and sells for around $55. The model number is 1665. The Packrats shown in this review are factory seconds and aprt from the four Xs on the blade, they're identical to factory knives in all aspects. It weighs in at 4.2 ounces and was designed by the master himself, Ken Onion.
The Handle: The Packrat is 4-1/8" long closed and 7/16" thick, not counting the pocket clip. It has 410-series stainless steel liners, one locking, and G-10 scales. the handles are held together with three black T-6 screws, which go into nuts on the right side of the handle. The blade pivot pin screw is black, and uses a T-8 screw.
The backspacer is black Zytel, and this holds the SpeedSafe in place.
The Packrat opens very quickly due to Kershaw's SpeedSafe assisted opening system. If you're not familiar with it, it uses a torsion bar to keep the blade closed. When pressure is applied to the blade on either the thumb studs or the index finger protrusion (like a flipper) and the blade opens past about 25 degrees, the torsion bar propels the blade to the locked-open position. It's very fast and very reliable.
There's also a lanyard hole in the butt and it's 1/8" in diameter, but I've found it too small to be useful.
The Packrat uses a brushed stainless steel pocket clip mounted on the right-hand side, and it's adjustable for tip up or tip down carry via black T-6 screws (two of them).
As you can see, tip down carry is just a tad deeper than tip up carry. retention in the pocket is good, but not great. It's plenty tight and placement is great, but the rough G-10 scales tend to drag a bit on the inside of the pocket. It's easy to get over, but will take a few tries to get used to.
The Packrat is a linerlock. The two I have are great; no blade play in any direction, and the liner engages the blade for its entire length on both.
The orange one engages the lock a little farther than the black one, but both are perfectly functional.
In use the Packrat is extremely comfortable. It's a very nice knife to use, and the ergonomics are outstanding. It's a nearly-perfect EDC.
