As the type of person that would totally give a book of 100 bread recipes to someone that I just know "bakes bread," I'm wondering if you think there are book gifts that someone could get you using that mindset and just a little more thinking about depth of domains.
One doesn't need to know anything about baking bread to know that a recipe compilation book is a beginner gift and not something you'd give to someone who has any sort of domain expertise. Similar to how I'm not giving any of my SE friends the Computer Science for Dummies book.
I guess what I'm trying to ask is... would a book about baking that isn't basic be a better gift? Even if it isn't particularly something you would have gotten yourself. Examples off the top of my head include a biography about a famous or obscure baker, an in depth book about the science behind baking, a hyper focused book about history of baking techniques, etc.
Maybe trying to gain some domain expertise in something your potential gift receiver is interested in - in order to give a better gift - is a gift in itself?
Here's a quick way you can get some functional domain expertise in knives to give a better gift to your knife friend (if you want). Depending on if they're into knives as collectibles or for use, I'd suggest finding out which brand(s) your friend favors and then picking up a used knife in a discontinued model from that brand on ebay. Worst case scenario they have it already but even then I bet they'd still value the gift.
