How to write "hasami"


I've seen the word for scissors "Hasami" written in hiragana " はさみ" katakana
"ハサミ" and kanji "鋏". which is the most common?




はさみ and ハサミ are both very common, and you can use whichever you prefer. はさみ is
definitely not a loanword, but there are words that are conventionally written
also in katakana. Animal/plant names are the best-known example (see
[this](https://japanese.stackexchange.com/q/20840/5010) and
[this](https://japanese.stackexchange.com/q/31148/5010)), but there are other
similar words (カンナ, ノコギリ, メガネ, クルマ, ...). Experts and enthusiasts may tend to
use the katakana version more often, but it's hard to generalize. When in
doubt, you can use a corpus like
[BCCWJ](https://ccd.ninjal.ac.jp/bccwj/en/index.html).

鋏 is not a joyo-kanji, and it's no longer common in modern Japanese. Some
native speakers may not be able to read it.
