## Description

Product Description Pattern (type): Combination whetstone set (#400 grit)Product Description:Product Specifications:Dimensions: (HxWxD): 2.2 x 10 x 3.7 inches (5.6 x 25.4 x 9.5 cm)Product Details:From desertcartA whetstone with excellent grinding power which wont get stuck easily.Sharpening holder and tray for an easier experience.Can be used with stainless steel and regular steel. desertcart.com Review ●研削力に優れ目詰まりしにくい砥石 ●使いやすさを追求した砥ぎ台 ●ステンレス・ハガネ兼用

Review: 思ったよりいい物でした、使用前水につけたり使用後乾かしたり面倒に思いましたが研いだ後の切れ味が凄く良くなったのでそのくらいの手間はいいかな、研ぎ台滑り止め付き、砥石も大きめ、しっかり研げます、研ぎ方も箱の裏に分かりやすく書いてありとても使いやすい、差し込んで引くだけのシャープナーを使っていましたがこの砥石で研いだ方が切れ味もよく長もちするように思います、よく自分で釣ってきた魚を捌くのですが切れ味がいいときれいに捌け仕上がりもよくなります、家庭用としては十分だと思います、満足です。
Review: 包丁を研ぎに出したら切れ味に感動して自分でもメンテナンスができないかとこちらを購入しました。 原産国が中国なのでどうかなとは思いましたが、レビューを読んで研ぎ方も動画でありそうなので決めました。 動画を見ながらやってみたら切れ味の落ちた安物の包丁が抜群の切れ味に！ 早く買えばよかったです。 初心者向けにはちょうど良い価格と切れ味だと思います。 料理が楽しくなりそうです。

とても使いやすくて切れ味も凄く良いです。 研ぎながら長く使えそうなので選んでみました。 食洗器も対応だし普段のメンテナンスが要らないのも良い！ 贅沢を言えばもう少しだけ重さが欲しかったですね・・・・・ 包丁の重さは切れ味にも凄く効いてくるので 軽ければ良いってもんでもないんですよね・・・・
