I've given away several, mostly to co-workers and employees. People who needed a knife for work but had no idea of what "quality" meant in regards to knives, and who wouldn't buy themselves anything more expensive than a gas station folder.
My rule for gifting knives to those people was to only give knives under $100. For under $100 I could give a person a very decent knife that could serve them well throughout their lifetime. But at the same time, I didn't have to worry that I spent big bucks on a knife that they might lose, or unintentionally destroy, or trade someone for a case of beer. The knives I've gifted to such people include Gerber, Buck, Spyderco, Benchmade, and maybe others that I can't remember.
By gifting what I considered "inexpensive" knives I also avoided any awkwardness that might arise if the recipient looked up the knife online and discovered how much they cost. The fact is, to avoid awkwardness, I've never let the recipient of a gifted knife know that I bought it for them. Instead, I'd tell them something like I found it and had no use for it, or that it was an old knife that I no longer had a use for. I've learned that when people find out that you BOUGHT them a gift that they often feel obligated to then buy you one in return. Or they felt awkward accepting the gift knowing that they could not afford to buy one in return. But by telling them I found it, or that they would actually be doing me a favor by taking it off my hands, all they felt was joy and appreciation.
And that joy was a gift to myself. It really is a nice seeing the reaction of people when they receive their very first QUALITY knife. To some on this forum a sub-$100 knife might not seem like a big deal, but to people only used to gas station knives, who can't afford to pay $50 or more because they have bills to pay and mouths to feed, a $50 knife, or something a little more expensive can be a great treasure. I've seen that reaction several times. And what a great feeling it is, a month or so later, to see that same knife all scuffed up from being used.
I've never gifted a knife to another Knife Knut, because all the ones I've known personally were capable of buying their own.
The only knife I've ever given to a family member is the Kershaw 5200 pictured below that I gave my father back in 1989. Again, I didn't tell him I bought it, he wouldn't have liked the idea of me spending money on a gift for him. He wasn't into knives or outdoors activities, and I didn't actually think he would ever use it. But I found it in one of his drawers after he died, scratched up, with the blade covered in tape residue and other crud. That made me happy. Now I carry it as my "public friendly" knife.
