This item is no longer sold. It's a short, swivel-head ratchet wrench from about 20 years ago. It was useful back then for changing the spark plugs on rotary engines. Depending on the use, it's a tool that can reach those tricky spots. The metal design, which you don't see anymore, is also cool. I think it was discontinued about 20 years ago. Thank you. #mactools #マックツール #ロータリーエンジン #fc3s #fd3s #se3p #rx7 #rx8 #snapon #スナップオン
