... gaffers tape. All my lighters have tape on them just for that reason.
I have a yellow highlighter (the fat kind) with 3 ft of gaffers tape on it that I keep in the left interior breast pocket of my Scotte, along with a bunch of other things. To the untrained eye, the contents look like a bunch of random "stuff." But gaffers tape on a highlighter, earbuds, croakies, extra schoepsnbox cable, 1ft of rolled up velcro, extra house key, external phone battery (but really a Baby nBox), etc., etc. -- are all little tools of the trade. Well - except for the house key.
