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!
