Senku stops, brushes Tsukasa off to inspect the edge of the blade again, running his finger along the bevel as he carries on, âWhen you get a bur like this, youâll switch to honing, which isâare you even paying attention?â Tsukasa blinks and knows he hasnât moved properly, still staring down at their handsâclose, so closeâas Senku glares up at him.
âMm,â Tsukasa grunts with a curt nod. Itâs not technically a lie.
Even though Senku squints, he lets it slide, vaguely skeptical. âYouâll have an easier time with swords because everythingâs scaled up, but with this youâll change your grip and move in a single direction.â He adjusts, then, and spreads his thin fingers wider across the spine, holding it steadyâgliding it across the stone in sweeping, smooth, even strokes before flipping and slowly sliding the heel toward their bodies again, pressed together. And Tsukasa hovers, wanting the touch back but not, as he watches the delicacy of itâthe confidence with which Senku handles something so dangerousâtransfixed.
Itâs only a chefâs knife but he feels the absence of Senkuâs hands on his own like a burn and wonders, distantly, if Senku handles all of his weapons with the same sort of care.
