Strikingly bold looks with a lovely feel and balance to this knife make it a great choice for an all round chef knife.

The Japanese equivalent of a Chef's knife, this is light as a feather and with a distinctive carbon blade is a delight to use as well as to look at.

What we thought about this knife

We have personally tested and reviewed this knife to give you an honest and personal opinion about it and this is how it rates.

5 / 5Overall performance

Handmade using incredibly strong Aogami Super carbon steel clad with stainless steel, the Koishi is extremely easy to sharpen and holds a brilliantly sharp edge which will be more than a match for anything in the kitchen.

5 / 5Beauty

Koishi translates as "pebbles" which is the effect the hammered finish of the blade gives. Combined with a matt, dark grey/black blade and cherry wood octagonal handle with black (pakka wood) collar this is one of the stand-out knives we sell.

5 / 5Durability

Aogami Super carbon steel is highly regarded for its hardness and ability to stay sharp although carbon steel does require a little extra care after use (please see "ease of care" section).

4 / 5Ease of care

Carbon steels can develop a "patina" which is essentially rust. This is a completely normal property of the steel and adds a unique character to the blade over time and use. It scrubs off (so don't worry!) and by following our carbon steel care tips, you will always have a unique knife in your collection!

5 / 5Comfort

The knife is lightweight and extremely sharp meaning you'll expend less effort cutting than with many other knives. The handle is comfortable and the shape sits well in your hand.

5 / 5Value for money

We rate these as one of the best knives we stock and have reviewed. The combination of blade quality, craftsmanship, appearance and sharpness mean we're more than happy to give it our best marks.

The technical bits

Our aim is to measure everything as accurately as possible but some specifications (such as hardness for example) are provided by the manufacturer and therefore should be used as a guide only.

What you get with the knife

Beautiful blue fibre boxes with the Masakage logo and name in silver foil on the lid. On the inside you will find a blue stepped inlay and your beautiful knife of course, wrapped in Japanese newspaper by the craftsmen who made it. So while not working on your knife skills you can catch up your Japanese language skills. Talk about the gift that keeps on giving...

All our knives also come with free blue plasters just in case you're not ready for the sharpness! If you intend to use your knives regularly then we don't advise you to use the boxes for day to day storage, get a magnetic knife rack instead.
