Don't think the wife needs one she would probably be using it on me so she could get my attention.
No problem and if I were a woman I would carry it while out MDing for sure since it has a flashlight and is a stun gun too.
Not all of us are advocates of the Old West or they live, or MDing, in a place that forbids the packing mama.
I do not abide by the laws when it concerns the protection of my family or myself and the states that allow guns but not stun guns has it bass ackwards anyway.
Looks like a knife to me and probably would to the cops who would have to haul you in.
You can bet your butt I carry on me at all times in the parks, on the sidewalk, or where ever other people can come up on me and put a world of hurt on me or kill me.
Just remember by order of the Supreme Court a cop's job is not to prevent crime but merely to sweep up after and sorry but I protect myself first because there is not a soul out there who will when I need it the most but me.
Don't worry I do carry my Lesche when hunting and keep it unsheathed at all times. Had this snot nosed twenty something punk demand my pouch once. I held my Lesche in front of me and said "no you aren't getting nothing and I haven't found anything valuable but a couple pennies anyway". Little punk backed down even though I am small lady. If he had reached out Lesche would have been in his chest or he woulda got whacked upside the head with a coil. Then kicked in the kahunas because I did study taekwondo and judo for 6 years.
