With so many multi-tools on the market, one might honestly ask why we are bothering to even write a review. The answer is simple. The majority of these devices, although nifty in appearance, contain tools that are more gadget than tool. Let's face it, who really needs a corkscrew in the boondocks? In addition, the knife blades on most combo-tools are pretty lame.

Hans Florine recognized this problem and designed the Bivy, which is truly useful with the tools that will be used on a regular basis. For those readers who are not familiar with Hans Florine, he is a world record holding speed climber and rigger for the world famous Bandaloop Vertical Dance Troupe. Jim may have jumped out of perfectly good airplanes in his younger days, but would never, ever consider taking on the mountains that Hans tackles.

When Hans designed this tool, it had to be right, because lives would depend on it. That is the primary reason we decided to test and review the Bivy.

One of the major improvements in the Bivy are the pliers. They are not only functional, but very strong. These pliers can actually be used on tough jobs and will hold-up, unlike most other multi-tool pliars that slip, bend and warp when you bear down.

This multi-tool also has a Tanto-style blade that is a real knife. Made of 5Cr15MoV Chinese steel (approximately equivalent to Japanese AUS-6), it is sharp, holds an edge reasonably well and is easy to sharpen.

If you own or have owned some of the other multi-tools on the market, you know what we mean. After a few uses, their knife blades are more like scrapers than knives. Oh, you can sharpen them, but after a single use, most of them are again dull. Remember, a dull knife is far more dangerous than a sharp one.

Lastly, Hans added a flathead screwdriver, Phillips head screwdriver and awl (marlinspike). That is it. Factor in the spring-assist button to open the pliers and you have a tool that does what is needed, when you need it.
