>>322221This is the bow drill set I keep at home.
The bow is the first one I ever made so it's got some sentimental value.
Pointless to take it /out/ with me but I still practice making them from time to time.
This one is what I use for showing off with when lighting the barbecue and teaching other people how to use one in the back garden.
Hearth is willow, spindle is birch, bearing block is holly and the bow is poplar.
Also OP, get a pack of disposable lighters and spread them all over your kit and pockets. You never want to be without one.
