How to say "chainsaw" in Japanese

• チェーンソー
  nounThe loanword for the power tool with a cutting chain; it covers the everyday sense of 'chainsaw', as in forestry work or cutting up fallen branches after a storm.
• 鎖鋸くさりのこ
  nounThe same tool written in kanji (literally 'chain saw'); it denotes the identical sense but is less common, so in speech the loanword is usually the word you want.

Both words name the same power tool: 「チェーンソー」 is the direct loanword and the usual choice in speech, while 鎖鋸 is a less common kanji-written synonym that learners seldom need.
