New tool-mongers Birzman are big on quality.The feathers of a bird inspired their Feexman penknife multi-tool range, and at 43g, the carbon-sided '5' is indeed light. The 3, 4, 5 and 6mm Allen keys and Phillips screwdriver handle essential tweaking jobs and chain care.
The £61.29 '10' model adds 2.5mm and 8mm keys, a T25 Torx key and a chaintool for a more comprehensive pocket pal. There are also better-value steel and alloy chassis options with various tool choices, priced from £15.32 to £33.71.
Whichever you choose, the hardened chromium-vanadium steel ones are tough, and can be replaced if they get damaged. While pricing is slightly over the odds, the luxury looks and performance of other Birzman tools make them stand out for tool fans.
