Released last year, Gerber's Artifact got people's attention- probably more than Gerber was expecting initially at least. I first encountered it at the 2008 SHOT Show in Las Vegas, and was instantly taken with it.
Gerber's Shard model is the little brother to their Artifact, and despite being about half the weight of the Artifact , the Shard is only marginally less functional.
The FROG tool by Gatco/Timberline is another interesting tool that defines and represents a whole section of the market. Like the Frosch tools, the FROG is a single piece of steel, cut and carved in such a way as to have multiple features, and let me tell you, it would be hard to add any more features to this one!
What kind of people would write collect and review multitools? Quite simple really- we are designers and do-ers, outdoors types and indoor types, mechanics, doctors, problem solvers and problem makers. As such, we have, as a world spanning community, put every type, size and version of multitool, multifunction knife, pocket knife and all related products to every test we could manage in as many places and environments as there are.
