I frequently get asked "so, Josh, do you have any more new weapons?" and I always like to be able to say yes, and whip out something.
The most recent addition to my armory, and toolbox is something small and sweet.
I have backed a number of things from Brad of Tactical Keychains, such as the with the classic WTF tool (and its variants) as well as the larger cousin, the Large WTF but also the very functional TiKeY key-keeper set, the very crafty TiPiK lockpicks and most recently the also magnet equipped TKMB pen
and the TiMag keychain accessories.
His latest creation was the Titanium Utility Knife Keychain or TUKK. this slim and highly engineered tool is packed with features in its small form. At just slightly over 2" long, 1/2" wide, and 1/4" thick it is easily overlooked on a keychain, looking for all the world like a USB stick, or something as innocuous. It weighs just 15g, (1/2oz).
The blade is a #11 Hobby Blade. (typically not included for regulatory reasons, but you can source them easily enough). Brad suggests Amazon as a source for the exact right fit, as the inside of the TUKK is milled to precisely take the blade. that milling is essential to the magnetic retraction, and retention that the TUK offers.
The two halves are held in place with two T-6 screws which can be opened with the right tool for blade changes. The main case is Grade 5 titanium, while the button is brass. I found that the springiness of the scalpel blade added to the retention and deployment of the blade. As you'd imagine, it's razor sharp.
A couple of neat things about the TUKK's design are that the imbedded rate earth magnet not only hold the blad retracted, when not in use, but also acts to draw it back into the body, by just the weight of the blade alone, when upturned. This is a great safety feature, requiring the user to maintain hold of the button, with only finger pressure, to keep the blade deployed, and let the scalpel do the work.
Brad has also thought to include 1/8" and 1 cm markings along the sides as he did with the WTF tools, as well as some nice inlays on the back side of the blade for grip. The built in magnet also adds one additional feature, it makes one side of the tool magnetic, so you can pop it on the side of a tool-box, pipe, shelf or wherever you are working, and have it out of the way and ready to access at a moments notice.
Also stay tuned, as Brad has a new Kickstarter coming up, the Magnetic Quick Release, the logical next step from the TiMag keychain accessories.
