The MakerPi Tiwrench Adjustable Wrench uses a worm drive for a secure grip

While many EDC manufacturers focus on combining as many different functions as possible, Hong Kong’s MakerPi has decided to focus on one thing: getting a solid, secure grip and perfecting that idea with its new tool. Called Tiwrench, it is currently available for backing on Kickstarter.

As the name suggests, Tiwrench is first and foremost a wrench that can serve as a compact tool for small, everyday repairs. Besides that, it also works as a fractal vise for DIY projects. We’ve seen similar compact fractal vises before, but they weren’t designed to be used as a wrench. Tiwrench covers both functions, so whether you’re an EDC tool collector, 3D printing enthusiast, or model building hobbyist, you’ll probably appreciate what this tool is designed to do.

With a traditional adjustable wrench, the jaw opening can often change after a few turns. The Tiwrench’s Archimedean worm mechanism addresses that problem, providing recoil resistance. Once you find the right opening for your needs, it will help keep the jaws securely in place. The thumb-operated adjustment knob has a knurled texture for better control, along with additional holes that can be used with a small metal rod when more force is needed.

Tiwrench can be used with three different jaw types and four material options, so you can choose the most suitable combination depending on what you’re working with. According to the creators, the jaws can be changed quickly and easily thanks to the ball retention system.

The fixed flat jaw is designed for hex nuts, bolts, square parts and flat objects. The single level adaptable jaw is designed for cylindrical and irregular shaped workpieces. Its contact surface creates the angle necessary to hold the object securely. The dual-level adaptable jaw provides even more contact points for various shapes and is designed to distribute clamping force more evenly. It can be used with small round, square and irregular shaped objects.

Let’s take a look at the jaw materials offered. Stainless steel is intended for harder parts where greater strength is needed. Brass contact faces provide a softer grip and work well with metal. Nylon contact faces are designed for plastic and 3D printed parts. And finally, the silicone contact faces are intended for objects that tend to slide easily, providing more contact and better friction.

Tiwrench includes a quarter inch mounting thread on one side of the body, making it compatible with camera mounts, magic arms, and workbench mounts. This feature could be used for filming, making the tool suitable beyond DIY projects and repairs.

The tool also has two magnetic slots on one side to store two short hex bits. Each Tiwrench comes with a PH0 Phillips bit and a 3mm hex head bit as default. As an added bonus, there is a laser-etched scale near the jaw area, with metric measurements on one side and imperial measurements on the other.

MakerPi offers Tiwrench in two finishes: aluminum and titanium, weighing 311 g (0.69 lb) and 397 g (0.88 lb) respectively. The jaw components included with the tool are made of stainless steel in both versions. Each Tiwrench comes with a single level jaw and a fixed flat jaw, while additional jaws can be purchased separately.

The tool measures 135 x 47 x 18 mm (5.31 x 1.85 x 0.71 in) and the maximum jaw opening is 18 mm (0.71 in).

The early bird price for the aluminum Tiwrench is $119, while the expected retail price is $188. The titanium version will cost $189 for early backers and $268 at retail. If the Kickstarter goes as planned, shipping will begin in February.
