Q: I’ve recently started training for a marathon, and with two small children I often have to get my runs in early in the morning or late at night when my husband is home to stay with the kids. I don’t like to run in the dark and would feel better if I could carry a weapon of some kind, but I’m not comfortable carrying or using a gun. Can you recommend a stun product that I can carry with me that will not be too bulky or awkward to carry, but still effective?

A: There are several small stun devices you can use, but the most befitting for a runner would probably be the Blast Knuckles. Packing a powerful 950,000 volts, the knuckles can easily fit in your hand, especially since when running most people run with a closed fist. Shorter in length than a dollar bill, it’s also easy to keep it relatively discreet so as not to make a passerby weary or frightened of you. A safety switch prevents accidental discharge, and a built-in flashlight provides that little bit of extra light to take away some of the darkness of running at night! Since it’s lightweight and easy to carry in your hand, there is no need for wearing clothes with a pocket or sticking it in your waistband, adding discomfort when, let’s face it, running is already hard enough! Also, you’ll have it ready at a moment’s notice should the unfortunate situation arise where you need to use it. Retailing for around $80, it’s an affordable alternative to bigger and bulkier stun devices.

Make sure to check your state laws for possible restrictions on use.
