Daysaver Minitool Review

Multitools are essential on any bike ride, but usually, you’re faced with the choice between lightweight or functional. The Daysaver Minitool aims to combine both. Weighing only 39 grams, with modular expansion and smart construction, it promises to be the perfect tool on the go. We’ve taken a closer look at this Swiss precision tool.

They come in all sizes and price ranges – from ultra-compact multitools to feature-packed half toolboxes. Some score with minimal weight but offer hardly any leverage and little comfort when wrenching. Others give a better grip but their bulky design often makes it impossible to reach screws on the intricate bike.

In short: Common multitools are either too short, too heavy, or too unwieldy. Daysaver wanted to eliminate these weaknesses and developed an expandable, minimalist tool.

The developers of Daysaver didn’t want just another standard multitool; they aimed for the one tool that does it all. Their goal: full functionality with minimal weight.

The result: A tool made from high-quality steel components with seven Allen keys (2–8 mm) and a T25 Torx. The bits can be flexibly attached to either end depending on the bolt position—this ensures optimal leverage and ergonomic working, even in hard-to-reach places. This clearly sets the tool apart from traditional, unwieldy mini tools that often fold up or are too short when working on bolts.

Despite its ultra-compact format, the tool appears meticulously designed. The precisely crafted bits can be magnetically connected, and the handle offers enough leverage to loosen even stubborn bolts—a point where many competing products fail.

You simply plug the right bit into the right spot and you’re ready to go. A bit inconvenient: if you need one of the larger bits, you have to remove the smaller options from the tool and set them aside while working. Since the small bits disappear into the forest floor very quickly, we held them between our lips when writing. Otherwise, you end up searching for the screws longer than it takes to repair the bike. With the chain breaker extensions or the box for easy storage, you can solve this problem. These extensions have magnetic spots where you can “park” the small bits temporarily.

The Kallsic Daysave Tool can be expanded with many options. With the Co-Working 6 TL, the range of functions grows so much that no wishes are left unfulfilled. Tire levers, chain breaker, spoke wrench, tubeless repair tool, and valve key can be seamlessly and magnetically combined with the original tool. Together, both tools weigh only 74 grams and replace half a workshop.

We also had the Guard Tool Protector in use. It offers minimal additional storage space for the tubeless repair strips and protects the tool from the dirt that inevitably comes with an MTB backpack. Additionally, the tool slides into any backpack pocket or jersey pocket without edges, without snagging on any sharp edges.

In practical testing, the tool impresses with high torsional stiffness and well-thought-out handling. The magnetic connectors hold the bits well, but sometimes a bit gets stuck in the wrench surface of the corresponding screw. Especially with the very small keys, you have to be careful not to lose anything here.

Even pedals or stubborn chain bolts can be loosened with the combination of Essential 8 and Co-Working 6 TL. The long lever is an important factor to make the tool truly practical to use.

It’s a shame: Unfortunately, standard drill bits can’t be used with the tool, as the hexagonal surface is not the same. Otherwise, you could expand the tool with any Torx or Phillips bit. Also, there are no individual bits or extensions available for purchase on the Daysaver website.
