うたい文句通りのギアの軽さ、かといって惰弱でもなく、きっちりトルクはかかる、それでいて、だいぶ緩んだ状態でもラチェッティング出来るほどの空転トルクの軽さ。ウホッ、いいラチェット、です。 首振りは便利、一応センタークリックはありますが、ロックがあればなおいいかも、と思った次第。四の五の言わずノーマルもそろえちゃいましょう、な価格、でもありますが。

想像よりしっかりしていました。工研のラチェットは使用していますが、Z-EALは今回が初めてになります。空転トルクは通常モデルと少し味付けが違いますが、やはり工研です こだわりが感じられます。値段も安く想像よりも丈夫そうです。エラストマ樹脂のハンドルは、MOKIナイフさん等のハンドルにも使用されていますが使用感は非常に良いです(柔らかい感じの手触り)。はじめは重いかな?と思いましたが、重量バランスがいいのか?使いやすいです。この値段でこの精度、工研さんは面白い企業ですね。ショップさんの配送の梱包もエコで無駄なく好感が持てます。

Z-EALシリーズいいですね。スタンダードのラチェットに加え 首振りも欲しくなり今回購入しました。空転トルクにばらつき?があるのか 新品だからなのか? ギアのカチカチ感が大きかった気が… そのうち馴染みますよね? これからどんどん使用したいと思います。
