At home: I use my Buck folder and Leatherman Wave several times daily. I use my small flashlight several times per week. I used my paracord for the first time ever, last week.

At work: I use my SAK, Leatherman Wave, & Mini Mag light daily. I've used my P-38 several times. The Magnesium Bar w/striker and photon light have never been used. I occasionally have need of my small pair of surgical scissors.

I use many apps on my cell phone for my line of business daily. My NukAlert hasn't gone off except when standing next to a friend within 3 days of his getting a hypodermic shot for cancer.
