Yes! Even with the serrated edge, the Keyzmo is 100% TSA compliant. We've yet to hear of a single problem or Keyzmo being confiscated for any reason. The serrated edge is in an enclosed area of the multi-tool and is not an external blade.

The screwdriver tips were specially designed to work with the 9 most-common screw heads. No other screwdriver tip can do this! It works with: #2&3 Phillips Screwdrivers, #2&3 Slotted Screwdrivers, a #2 Square Drive Screwdriver, #2&3 Combo Phillips/Slotted Screwdrivers, and the #2&3 Combo Phillips/Square Screwdrivers.

The closed wrenches have both the popular Imperial and Metric sizes! The Imperial Closed Wrench includes 7/16, 3/8, 5/16, 1/4, 3/16, and 1/8 sizes. The Metric Closed Wrench works with M8 (13mm and 1/2), M6 (10mm), M5 (8mm), M4 (7mm), M3.5 (6mm), and M2 (5mm) bolts/nuts.

We've gone through dozens of prototypes to ensure that the tool is both comfortable and effective. When driving a screw, it's very comfortable in your hand and you can apply a good amount of torque because of the tool's flat shape.

Yes! Keyzmo is ergonomically designed to apply enough torque to break loose even stubborn nuts and bolts. Simply place Keyzmo's closed wrench in a position over the nut or bolt so when applying torque, you are pushing on the “file“ portion (the neck of the key). That way you'll have a nice flat part to push against.

Keyzmo’s state-of-the-art 420 stainless steel construction has a ton of benefits centering around its unmatched durability and convenience.

It’s sure to stand up to any task you throw its way – and the durability is proven by its rust-resistant, strip-resistant, and flameproof properties.

Keyzmo’s compact size and lightweight design ensure it’s easy to carry with you everywhere. Keyzmo is also dishwasher safe so it can be cleaned or disinfected after every use. The material is also magnetic, making it convenient for storage.

The Keyzmo is just slightly larger and thicker than your typical key – for good reason. It’s purposely thick enough to not bend, crack or break when tightening and loosening even the most stubborn screws, bolts, or nuts. It’s also large enough to give you enough torque to properly secure or loosen those screws, bolts, or nuts, yet small enough to easily fit on your keychain and put in your pocket.

The exact measurements of Keyzmo are 2.76” wide x 1.15” tall x .2” thick – and it weighs just 0.75 oz!
