They used to call me the knife fairy at work, because I gave away so many...
Here are my experience giving away knives:
To knife/outdoorsy people:
Spyderco Military FS S30V: well received, uses often
Spyderco Manix 2 S110V: (very) well received, knife was thoroughly thrashed for 3 years then lost in the wooooods

Cant believe I just made a frozen 2 reference, forgive me BF...
Artisan small archaeo (fancy damascus one): well received, Europe carry, display piece
To non-knife people (aliens?):
QSP/Bestech etc kitchen knives: very well received, people think they're awesome even though they're usually 60-80$. Dont get me wrong, they're quite good for the price, but looks are slightly deceiving
Shun kitchen knives: I've given away a few over the years, people are generally disappointed by their plain look (unless it's a kaji, hikari, fuji, etc) but get happier as they use it more
SAKs: given tons of these away. I try to buy ones that fit the person and they've been generally forgotten and not carried. I feel that if they did carry it they'll appreciate it
Bark River: yes I gave a non-knife person a bark river. It was well received for being pretty but not really put to much use
Boker Magnum Mermaid: surprisingly, people think these are some expensive knives and display them
GEC keychain 05: gave it to a girl. It was returned to me and I'm still single
That's the recent ones I can remember...cheers.
