There are plenty of women who feel uncomfortable using "men's tools" unless they are pink, that's for sure. Case in point: how do you know if a razor is for a man or a woman? The woman's razor is pink. Kind of like how there are plenty of men who feel uncomfortable hugging each other, even with just one arm, unless they're slapping each other hard on the back. I guess it all depends on how much you define yourself by the things you own.
My mom likes my Gizmos because they remind her of the metal machining her father used to do, back in "The Olde Country".
Each to their own, a woman can certainly use and carry mens tools etc. I'd hug a friend I haven't seen in a long time, but I won't carry a pink light! That said, reason for my idea is that I haven't seen many custom flashlight builders make anything girly/woman dedicated in the "usual" fashion.
Girl colors, etc. First guy to cover a Ti light in diamonds will get a sale from Russia once the light is found. I'd go for swarovsky crystals instead. Gave my gf a pen like that once you would believe the squeal I got from her. Girls love glitter.
