The outer width of both ends of the CNW-2 are nominally 12mm wide. One end has a two outer tips nominally 2.7mm wide each, and the other end has tips of 3.8mm each. The blade thickness is nominally 1.35mm

Pretty Poor, But Cheap.

I had to take a dremel to this and trim the edges as they were too tight.
If your bolts come through the back sligtly then this tool doesn't fit.
It just about does the job after my modication however.

If your bolts don't come near sticking out the back at all this should work fine, but why they didn't just make the gaps 1mm wider to allow for this I don't know.
Useful Tool

Expensive for such a simple tool. The locating spigot could be slightly longer and wider. A suitably sized flat bladed screw driver might also work instead.

I was able to undo and retighten my Stronglight double chainring bolts with the help of this tool. They unscrewed and tightened easily, but required a slight force to prevent the nuts from turning, which this tool did easily.

Tangs are too short to reach the chainring nuts on a single_ring (short) bolts.
Makes doing_up double_ring bolts easy.
