I originally purchased the Gerber EAB a couple of years ago in an attempt to shelter my nicer pocket knives from the abuse of opening and breaking down cardboard boxes at work; cardboard dulls blades quickly. Of course, it’s also great at all the other miscellaneous tasks suited to pocket knives.
The EAB (exchange-a-blade) is essentially a standard utility knife redesigned to be an every day carry knife. There are plenty of utility knives on the market that have been designed to opened up like a folding pocket knife, but this is the only one I’ve found that is small enough and light enough to carry in my pocket every day. It’s just under 2.5″ in the closed position, and weighs about 2 oz.
The clip is wide enough to serve as a money clip, but it’s also stable and deep enough to ride well in a pocket without wiggling loose. The blade itself is reversible, and when it wears out it’s replaceable with inexpensive standard utility knife blades (which sell for about a dollar). The EAB has a nail nick for opening with a thumbnail, but it’s also opened easily enough with one hand by using the set screw as a thumb stud. A liner lock keeps the blade from closing on your finger when it’s in use.
Overall, the EAB has been a workhorse of a knife, and has earned a permanent place in my pocket. I haven’t lost mine yet, but when I do it’s cheap enough that I won’t hesitate to replace it. And I love that I don’t have to sharpen the blades — I either flip them around, or just replace with a fresh one.
