Here, copied from our UK BritishBlades forum, is my neckchain kit:
"I've seen one or two threads about Brit knuts wearing neckers while cycling or jogging. Having just returned from an 11 1/2 mile "burn-up" on my road bike (42 mins, average speed 16.1 mph...) I thought I'd pass on some details of the neck kit I wear.
A dog tag with name, address, phone number, any medical notes etc.
An Arc AAA torch (thanks, Harvey!)
A Spyderco Ladybug
A Perry whistle
A large Spy Capsule containing matches in a 2" x 2" zip-lock bag; also 3x 400mg Ibuprofen in a separate zip-lock bag.
A Sun MiniComp II compass
A Ronson disposable lighter
The Ladybug, compass & lighter are supported by passing the chain through the Ladybug's lanyard hole, then sleeving all three items in a 2" length of bike inner tube. This holds them tight, prevents rattling (and camouflages the lethal, terrifying Ladybug...)
I also carry other kit in my pockets, e.g. a Gerber multitool, SAK etc."
I have also recently added (after a recommendation on BF) an
Aeroasso Pocketwrench
