Benchmade Mini-Grip. All black blade, so that was part of the problem. I was also in a Bath and Body Works.
Wife's friend works there, and I think I was Christmas shopping. We were talking, and she kept rubbing her finger. I asked why, and she said she got a splinter of glass from a broken bottle.
I asked if I could take a closer look, and she held out her hand.
Thanks to good lighting, I could see it was a long, thin, nasty shard of glass that would simply crush if she tried to grab it with a tweezers. But, with the blade of a knife, it might be possible to scrape it out.
I should have asked her first, but I wasn't thinking about her colleague, a "biddy", who had probably not seen a knife used in everyday settings since she visited her Grandpa's farm for Christmas, as a girl.
I pulled and opened my Mini-Grip, all 2.97 inches of blade, in one smooth motion, to scrape the glass out.
The older woman jumped, and gasped. "Oh my gosh! He has a knife!"
My wife's friend replied calmly, "that's okay, I trust him".
I removed the glass, and handed it to her, from where it made it's way into the trash. I folded my knife, and turned to the other woman.
"Now you've seen a knife do something good. Remember that."
Then, I walked out of the store.
