CHARACTERISTICS

  • Sharp Ever After

    Get the most out of your knives.
    With the 2 different grits, you can conveniently keep your knives razor-sharp yourself.

  • Safety First

    The KOTAI 180/800 Combination Whetstone is mounted on a rubber base for stability.
    Not only does this make it safer for your fingers, it will also allow you to keep the sharpening angle constant.

  • Prolong The Life of Your Knives

    If your knife’s blade edge gets dented or too dull for the regular honing steel, the whetstone will help restore its original razor-sharp edge with minimal waste of steel.
    Soak the whetstone for 15 minutes before use (until air bubbles stop coming out of the stone).

The KOTAI 180/800 double-sided whetstone offers you 2 grits to sharpen your knife with a single stone: a coarse 180-grit side to reshape a dull blade and rougher edges, and a finer 800-grit side to maintain or give a razor-sharp edge finish.

Our 4-piece sharpening set contains everything you will require to keep your blades razor-sharp at all times.

Hochwertiger doppelseitiger Schleifstein, welcher eine gute Ergänzung im Haushalt ist

Ich hatte schon vor einiger Zeit einen Schleifstein für mein recht teures Messer besorgt und nun bekam ich die Möglichkeit und durfte dieses hier testen.
Der Schleifstein ist zwar recht teuer, aber dafür ist dieser doppelseitig und eine Anleitung sowie Zubehör ist auch mit dabei, was vor allem auch Anfängern weiterhelfen könnte.
»Inhalt«
- ein Schleifstein mit der Körnung von 400/1000 (Wasserstein)
- ein rutschfester Bambusboden ist vorhanden
- eine 15°-Winkelführung ist auch mit dabei
- Anleitung für die richtige Verwendung des Schleifsteins
»Verarbeitung und Qualität«
Der Schleifstein sowie das kleine Zubehör ist hochwertig und sieht gut verarbeitet aus. Außerdem gefällt mir das Design, obwohl es nur ein Schleifstein für mein Messer ist.
Somit kann man sein geliebtes Messer auf Dauer scharf und robust halten.
»Fazit«
Wenn man nicht Profi ist, sondern Anfänger, dann kann man sich leicht durch die Anleitung das benötigte Wissen aneignen. Dadurch werden Fehler recht gut vermieden und man kann sein Messer scharf halten, damit man keine Probleme in der Küche bekommt. Preislich zwar recht hoch meiner Meinung nach, aber dafür gefällt mir die Qualität, welche man dafür bekommt, auch wenn nicht alles perfekt ist, aber ich habe bisher nur einen anderen Schleifstein ausprobiert und fand die Idee, wenn man selber sein geliebtes und teures Messer wieder scharf machen kann, sehr spannend.

FREQUENTLY ASKED QUESTIONS

What is the steel used for the blade? Will it rust?

This knife is made of 440C steel from Japan. 440C is a high-carbon stainless steel, meaning that it combines the property of high-carbon steel (very hard due to the high carbon content of 0.95%+ and the vacuum heat treatment, therefore very sharp and able to keep its edge for much longer than other steels) and stainless steel (ability to resist corrosion and stains). So the blade will not rust, but you have to care for it properly by washing it with soapy water and drying it quickly after using it.

Do not put it in the dishwasher or leave it to soak in the sink.

Is it worth buying this knife or should I just get a 30€ knife from Ikea?

A “cheap” knife will end up costing you more in the long run, because it can break or turn dull. Low quality steel will not keep a sharp edge no matter how many hours you waste on sharpening, and you will end up having to buy a new knife every year or so.

There are plenty of “cheap” knives that cannot perform to decent standards and very few options for chefs who are passionate about cooking, need the right tools to assist them in their career or hobby but are not willing to overspend on a brand name. Get your KOTAI knife today for a lifetime of safe and delicious cooking.
