SHARPAL 194H Holdbubble Whetstone Knife Sharpening Stone Angle Guide Chisel Sharpening Guide Knife Blade Angle Meter Knife Sharpening Trainer (Angle 15°～45°)

I paid 3 times the cost of the product, I can't say if that was a wise decision, I was really testing the waters as I had never ordered from amazon.jp, But I am glad to say that this sharpal device helps you in maintaining the angle as you sharpen the blade with quite a good amount of accuracy, Since I already have a hang of it, This allows me to be a bit more precise. Also its got a magnetic base and not grinding on the stones surface hence its not going to wear out unless the magnet itself looses its magnetic strength. It's good for beginners who would prefer freehand sharpening on stones. Point to be noted - It will not work on small knives. Best for kitchen / chefs knives

包丁を研ぐときに、角度がわかっていいかも

砥石で研ぐときにちゃんと15度の角度が維持できているか確認する目的で購入。 当たり前だが両刃の包丁を研ぐ時は裏返すたびにコレを付け替えないといけないので、私のように#400、#600、#1200、#3000、#8000と番手を何度も変えて何度も包丁をひっくり返す場合にはめんどくさくてやってられなくなり、途中で外してしまった。 しかし、これのおかげで切先（先端）付近を研ぐ時に角度が高くなる自分の癖が掴めたので、まあ役割は果たしてくれたと思う。 価格も控えめなので練習用として買ってみても良いかも。

磁石でピッタっと刃物に付きます。角度を合わせて気泡が中心になっているのを見ながら研ぎます。 角度計は大まかですが、一定の角度を保って研ぐ目安になります。 機械研ぎの時はかなり便利かと、砥石は水平にしないといけません。

これを使えば包丁が簡単にうまく研げるというものではありません。あくまで角度測定機で研ぐ時の角度がこれで決められるわけではありません。使い手の腕に依存します。これを使って練習しなければうまく研げるようにはなりません。

包丁の幅より小さく、どう使って良いかビデオを見ても解らない！

I truly didn't expect to like this little device as much as I did. But I figured it was cheap enough that it was worth trying, and I'm very glad that I did. While it's not better than a simple angle pyramid for finding a good starting angle, one thing it's truly excellent at is giving real-time feedback of subtle angle drift and showing if you're under or over correcting when tilting for a curved blade etc. That really helped me a lot, and also helped to find a technique that introduced the least amount of angle wobble. I had been doing full, straight passes but it showed me that I could keep an angle much more steadily if I used smaller back and forth passes than longer, single direction ones. I think this is a great little trinket for the beginner sharpener. The real-time feedback is excellent and something not really achievable without HIGHLY specialized tools (high hz inclinometers, basically none on the market and only available as specialized DIYs) and even the ability to dial in an angle that isn't just "15° or 20°" like a lot of the angle pyramids and the like. It was definitely designed by someone who understands the process of freehand sharpening and it shows.

刃物を研ぐ時の角度維持が簡単にできます。

Thank you thank you thank you SHARPAL, i’ve used Whetstones, Rollers, Lansky systems and none of them worked anywhere near as good as this diamond block. Very easy to use a there’s no water and in turn no mess!!! I went for the bigger size as it gave me more room for the knife, the quality is top tier and the magnetic angle guide is really helpful for beginners. I was pleasantly surprised by the price too because the Lansky system was nearly double what i paid for this. All in all a perfect sharpener for a beginner or seasoned pro. I also recommend the double sided leather strop, really finishes the blade off.

Great little product! I have had no real luck using a whetstone till now, my angles were all wrong and not consistant. the trick is to keep the speed you push the knife forward on the stone nice and slow so the bubble doesn't move uncontrollably. sharpened all my kitchen knives wood plane and chisels. for me a game changer!

bueno y fácil de usar
