First aid kit was taken as standard even on lowland walks in populated areas, as a 'might be needed'- plasters particularly. Repairs I deemed not really important on a day hike.
I suppose the point I didn't make with my post is the one made by plenty of others in this thread- it depends. Do you need a survival kit heading out to the supermarket in the UK? No. The more exciting the activity- hillwalking, caving etc- the more likely you are to end up in unforseen circumstances beyond the 'will be needed' and 'might be needed' items.
classic case of diffent things for different people, i have a belt kit and the repair items are used all the time when im working, often away from car, head torch, elatehrman, poncho, ducttape, gluesticks etc.. so very heavy on repair items, .and because carrying sharps always FAK on belt , but this kit is for use in a city mostly......... but when im driving 3 miles to aldi with wife, i only take phone and wallet....
