[ There really is a lot of work to go into the simple maintenance of a weapon. But it's... interesting, and Lapis finds herself much more invested in his explanations than she was expecting. She had wanted the information just for future use, but there's genuine curiosity there now. So she's still and quiet as she watches - mentally filing away all this new information - arms folded over her chest as her eyes stay focused on the movement of the file against the blade.

So that brings back the natural edge... Okay, she's starting to get it. And that's why there's no hesitation when she nods at his question. ]

Mmhm. File at about a 30 degree angle and since it's curved, do it in sections with equal strokes on each side of the blade. [ See, she's listening! ]

It's a lot more interesting than I was expecting.
