A living list of the tools we recommend for multitool maintenance, modification, and repair. Whether you're doing routine cleaning or a full disassembly, using the right equipment prevents damage and makes the job easier.
Screwdrivers
A quality driver makes all the difference on small fasteners. We use the Wera 838 RA Mini Ratcheting Driver for fast, comfortable driving. But one is not enough, so we turn to the 711L pen driver for a versatile, secondary option.
Torx Bits
Most multitool models use Torx screws. A complete kit should include two each of T8, T9, and T10s — the T10s tamper-resistant is the most common. A single T6 is also useful for removing pocket clips on Leatherman Free series tools. We prefer Wera bits for their longevity and precision machining.
Specialty Wrenches
Knurled nuts on Leatherman tools and lobed screws on Gerber models need a precise fit — standard pliers will chew them up. We make specialty wrenches designed specifically for these fasteners.
Pliers
If you need pliers for pivots or stripped screws, Knipex Twingrip are the pick — precision machined faces that bite into fasteners of all sizes without slipping.
Heat Source
Manufacturers commonly apply Loctite to screws. A brief application of heat softens it and prevents stripping on removal. A soldering iron or small butane torch both work.
Poking and Proding
For knocking out pins and stubborn pivots without damaging tool components, brass is softer than steel so it won't mar surfaces. For manipulating more delicate components, a nylon spudger and a good set of precision tweezers is invaluable. We like these from iFixit:
Work Holding
A small hobby vise is a surprisingly helpful third hand during disassembly and reassembly, keeping your work stable while you drive screws or manipulate parts. Make sure it has soft jaws so you don't damage your tool!
Lubricants
A light multi-purpose oil for chassis cleaning, and a dedicated pivot oil for long-term smoothness. We recommend Knife Pivot Lube (original formula) for pivots.
Attempting repair or modification may void your manufacturer warranty. Proceed at your own risk.
