So I was wondering, how often do we use all this stuff we carry around? small knife/SAK: once a day larger knife: 1-2 times every other day large multi-tool: once or twice every week or two. small multi tool: 1-2 days a week wallet: money or credit card - 1-2 times a day - various forms of ID 1-2 times a week. mini prybar - once a day small one piece multi-tool on keys - once a day small flashlight - 1-2 times most days large flashlight - 1-2 times a week in summer, 5-7 times a week in winter. handkerchief/bandana - a few times a week pen/pencil - 2-3 times a week in summer, 10+ times a day during the school year notebook/day planner - 1-2 times a day pocket FAK - 2-3 times a week larger FAK - once a week paracord - once a month or less, unless I'm on a bracelet making streak whistle - Lifeguard - 4-5 times a day. School aide - Once every 2-3 days. General use - once a week USB flash drive - once every week or 2 during summer, 2-3 times a day during school year Spare change of clothes - 1-2 times a week during summer - once a month the rest of the year Phone - between 1-5 times a day... yeah I'm one of those weird people that hates phones and rarely texts and doesn't use their phone for anything else. duct/duck tape - once a month or less. So, that's all I could think of on a moments notice though I'm sure there's other stuff I forgot to mention. I'm looking forward to comparing my usage and edc items with yours.
