A light, superficial wound on the skin, such as from a sharp object or a rough surface. Often used in contrast to deeper cuts or serious injuries.
I fell and got a graze on my knee.
It's just a scratch, so it'll be fine if you put a bandage on it.
minor damage; slight harm
Figurative use for trivial damage to objects, reputation, or situations, implying the harm is negligible. Often used in phrases like かすり傷にもならない (not even a scratch).
A mistake of this level is not even a scratch to the project.
His reputation didn't suffer even a scratch.
Common mixed kanji-kana spelling; the kana portion かすり is often written in hiragana.
Kanji spelling using 掠, which is less common but still encountered.
Kanji spelling using 擦, which can also be read すりきず for a similar meaning; context usually disambiguates.
Compound of かすり (連用形 of かする 'to graze, to brush against') + 傷 (きず 'wound'). The kanji 掠 and 擦 both convey a sense of light contact or rubbing, but the word is most commonly written with the kana portion かすり.
