- Why the Runwell Aqualia15 spanner sets my heart aflutter
- These spangly spanners will tweak your bolts of desire
- Park Tool finally made a JIS screwdriver, plus more Eurobike tool highlights
I wrote about these beauties when I first saw them at Eurobike last year, and now I’ve laid hands on a set to play with.
Why do these even exist?
What if I said you’ve been using the wrong screwdriver for your bikes this entire time? Until Shimano started using hex-head screws on some of its derailleurs relatively recently, you needed a cross-head screwdriver to adjust your high and low limits.
You’d be forgiven for assuming Shimano limit screws have a Phillips head but, in reality, they’ve always been JIS (Japanese Industrial Standard), which require a subtly different screwdriver tip design for the best possible fit.
The subject of standards is a confusing and murky one, as it appears the JIS specification for screwdrivers has been absorbed into the current DIN 5260-ph (DIN is the Deutsches Institut für Normung or German Institute for Standardization). If you’re interested in geeking out on this subject, this article on motorcycle site webBikeWorld is worth a read.
In any case, Park Tool describes the DSD-2 as being “built to exceed JIS standards” and since it’s made specifically with limit screws in mind, you can be confident it’s going to fit.
Beautiful tools are the best tools
If you love tools, Park Tool’s new screwdrivers are delightful. They have a real heft to them, weighing about 50 percent more than the working man’s SD-2 Phillips screwdriver.
Do I need Park Tool’s new screwdrivers in my life?
At £30 / $35, Park Tool’s new screwdrivers are a bit of a luxury and the flat blade DSD-4 is hard to justify over more affordable alternatives.
All the same, the new Park Tool offerings are lovely objects that fit their intended usage perfectly. I’ve long been of the opinion that you’ll never regret buying good-quality tools, and I can’t imagine you’d feel much buyer’s remorse with these in your toolkit.

Thanks to my former BikeRadar colleague Dave Rome for piquing my interest in niche screwdrivers way back in 2015. If you like tools, I’d recommend following him on Instagram.
