I do this too. Though instead of a hard-boiled egg, I like to fry one so the yolk is still a little runny, and put it on top.
Recently, I’ve been making a vinaigrette with olive oil, vinegar, dijon mustard, salt/pepper, honey, and Lao Gan Ma spicy chili crisp. It’s pretty damn good.
Well, firstly, there’s the artistry of it. Creativity can be very sexy; it’s a kind of intelligence, after all. Hence writing, cooking, painting, ect. also being on the list. Not to mention, wood is a beautiful medium overall… and it smells nice when freshley cut.
Secondly, it’s attractive to be good with your hands. Not just because of the obvious, but because it’s genuinely admirable. It’s a show of competence (or at least one kind of competence) and requires one to be hard-working, dedicated, passionate, and persevering. All pretty universally attractive traits.
A carpenter’s hands may be rough and scarred, but they’re rough and scarred because they’ve literally crafted furniture/boats/houses/whatever. That in itself is pretty attractive to me.
Personally, hand tools, because they require one to use more of their own power, if that makes sense. Plus, power tools are a little too dangerous for me to see them in a sexy context lol. Frankly, the tools themselves don’t really do much for me.
