There are only three Brewzers available according to the seller, so if you want one, buy it now.
If you're not sure about the Brewzer, read a full review of it before buying, or see how it stacks up against the Gerber Shard.
On this site you'll find reviews of all sorts of tools -- hand tools, power tools, automotive tools, electronics tools, etc. More tool reviews will be added as often as possible.
The Vise is not very heavy for a multi tool (only 2 ounces) and sits much more comfortably in your pocket than Gerber's Mini Suspension-P. It has a good range of tools built in: spring-loaded pliers, cross and slotted drivers, straight-edge and serrated knives, bottle opener, and files.
The straight-edge knife and serrated knife are both good. They compare well to knives on other multi tools. Neither locks in place but that's typical for the price range that the Vise falls in.
Overall, the Vise is above average as a pocket multi tool, and better than many tools in the low-end price range. It's on a comparable level as the Leatherman Squirt -- a tool that often costs more than twice as much. The Vise is a better everyday tool than the Mini Suspension-P, mainly because the cross driver comes out much easier and is machined more precisely.
