I purchased a CRKT KISS and a PECK for my wife a few years back, after her mentioning that I seem to use my edc knives on a regular basis. She was very appreciative of the gift. The knives now reside in her jewellery box, and I STILL catch her trying to open packages with her teeth

. Whenever a situation arises where she needs a knife and I'm present, she doesn't hesitate to use one of my folders, but she never carries her own. I've often thought about why:
It can't be that she's squeamish around blades, because she's a neurosurgeon by trade. She does things with a scalpel that make ME feel squeamish sometimes.
I'm also not sure it's a design issue. I went for the KISS becuase it's very sheeple friendly, and it is useful for small everyday cutting tasks (although I find it way too puny for my needs). It also doubles as a money clip, which I thought would be a good selling point. I offered her a larger blade (an M16Z), but she said she wouldn't carry it around. I've come to the conclusion that it has nothing to do with the type of knife.
So, ruling out squeamishness and aesthetics, I think there are two remaining explanations. It's probably a combination of the two. First, I think there's the issue of sheeple-friendliness. It took a while for me to prove to her that a good knife, when used responsibly, is a valuable tool and NOT a weapon. Although I eventually convinced her, I'm not sure if she's willing to fight that same battle on behalf of her own knife use. Second, and perhaps more importantly, I think my wife, like many people in our society, has lost sight of the versatility of simple tools such as knives. We live in a world where everything is hyper-specialized to a specific task; I think the idea of carrying around a few basic tools to take care of everyday needs has become lost on most people.
So those are my thoughts on my experience of purchasing knives for my wife. I'm confident that she'll eventually come around. In the meantime, she has no problems with me buying lots of knives for myself (or sharpening them at the dinner table), so I can't complain!
Cheers,
Mike
