The thing about a small knife and a little flashlight is that you don't actually think about how many times it would be nice to have one of those things "right there right now" until you start carrying them. But a cheap little $15 flashlight that can clip onto your pocket and give it a try for a couple weeks, and you'll start to notice how convenient it can be every time you want to check something in a darker area. It's faster, brighter, and smaller than the light on your phone. This "WARSUN T7PRO Pocket Flashlight" is only $10 on amazon. It's not the greatest but you'll get the idea of always having instant light.
