  1. Masashi Kobo Mioroshi

Masashi Kobo Mioroshi
Filleting Knife

More Information

The single bevelled Mioroshi is a lighter weight filleting knife, lying somewhere between the heavier Deba and the more slender Yanagiba. Although the blade is not as thick as a Deba’s, it is still substantial and will deal with medium-boned fish, but is also delicate enough for slicing and portioning - A great all-round knife.

Masashi hand forges these himself in his workshop in Sanjo, Niigata. He hand laminates the shirogami white paper steel to the softer steel jigane cladding, and attends to every detail himself. Masashi trained under his uncle Yoshida-san at Yoshikane knives.

Tips

    Although this is a heavier weight knife, it is NOT suitable for cutting through meat bones.

    Masashi Yamamoto trained under his uncle, Yoshida san at Yoshikane, and produces knives of stunning quality - primarily in his signature SLD steel, a hard wearing, very-nearly-stainless-steel. In 2018 Masashi moved his forge to a new factory in Sanjo (in Niigata Prefecture) and now has two apprentices working with him.

    We think he looks a little like Christopher Walken, and he claims to be a children’s ski instructor - something we don’t doubt.

    Knife Care

    For better or worse, Western knives are often seen as general purpose kitchen tools, used for cutting, prising, levering and all sorts of other jobs around the kitchen (and sometimes beyond).

    Japanese knives should not be viewed this way and it may require a change of mindset to get the best out of your knife and ensure it delivers many years of service.

    Cared for correctly, this ought to be the case: the quality of the craftsmanship and the ease with which they can be kept incredibly sharp are two of the main reasons to make the switch to Japanese steel, but that comes at a price: the steel –especially steel with high carbon content - may be more brittle than you are used to and they are not for the heavy-handed or the careless. They are unforgiving tools and you may not get an opportunity to make the same mistake twice.

    A good rule of thumb is to show them the same respect you show your poshest wine glasses, but here are some other pointers.

    Commons mistakes to avoid:

    • Leaving wooden handled knives to soak in water.
    • Washing knives in the dishwasher.
    • Not storing them carefully: store them individually, not jumbled up with other cutlery.
    • Cutting into bone. If you’re not sure whether there’s bone, or you know there to be bone present, go very slowly and carefully, or consider using a different knife.
    • Trying to cut frozen foods.
    • Cutting down too hard on to the wrong sort of surface, for example kitchen worktops.

    Don’t be put off. They are great to use and easy to care for. To get the best from your knives:

    • Wash them by hand and dry thoroughly afterwards.
    • Wipe over with Camellia Oil if not using regularly.
    • Sharpen every two weeks or so of regular use.
    • Use the Niwaki Combination Stone for everyday sharpening.
    • Take care with harder foods, such as the skin of a pumpkin or a squash.
