EDC multi-tools are a game of give and take. The best ones pack a ton of functionality into a relatively small, pocket-friendly format. Yet some are far better than others at saving space or offering utility, but usually not both.
The EDC Monster KeyMaster 2.0 might just be the best of both worlds. This positively tiny keychain multi-tool packs the functionality of many twice its size or more.

Are you the key master?
The core consideration of any keychain multi-tool is its size. One that’s too long will stick out like a sore thumb, and if it’s too heavy, forget about it — it’ll bog down your whole keychain.
Neither of those are a problem for the KeyMaster 2.0. As its name suggests, it’s about the same size as a standard house key. For reference, it measures just 7.0 centimeters (or about 2.75 inches).
While it’s a bit thicker than a house key — probably closer to three or four keys stacked on top of one another — it’s still exceptionally lightweight at just 29 grams. That’s only a hair over a single ounce.
