Two things I like very much. Flashlights and knives. This Nestsun Tactical Flashlight Knife ($15) is fairly priced and has pretty good reviews as well. The flashlight is powered by a rechargeable lithium 18650 battery and uses a 250lm cree LED. There are three lighting options (high, low, and flashing), an adjustable zoom ring, and an expected range of 300-meters. Inside the handle is a knife and at the end of the handle is a window breaking hammer. Included with the tactical flashlight/knife is a battery, charger, and plastic storage box. Not bad for under $15!
