Buying your first Japanese knife often means facing a wall of technical information: sharpening angle, HRC hardness, single or double bevel, carbon or stainless steel. Most online guides pile up these concepts without ever simply answering the question you're actually asking: "Which one should I buy to start, without making a mistake?"

This article draws on what we observe concretely at Kaitsuko over 5 years: the questions we receive most often in messages, the recurring mistakes of new buyers, the feedback gathered from nearly 100,000 orders who took their first steps with a Japanese knife. No unnecessary jargon, no affiliate-driven recommendations - just what genuinely works for getting started.

Why a Japanese Knife Is a Good Choice, Even for Beginners

You might think a more technical tool is reserved for experienced hands. Our customers consistently show the opposite. A standard Japanese knife is bevelled at around 15° on each side, versus 20–22° for a classic European knife. This difference produces a finer edge that penetrates food with less pressure.

In practice: less effort for the same result and that's exactly what reassures a beginner. You push less, you slip less, you control better. With a blunt supermarket knife, the instinct is to press harder, and that's precisely when cutting accidents happen.

Add to that steel hardness, measured in HRC units on the Rockwell C scale. A steel at HRC 60 resists dulling approximately twice as long as a steel at HRC 54–56. For a first purchase, we recommend staying in that second range: a more moderate HRC remains highly effective while being easier to resharpen yourself, without specialised equipment.

If you want to dig deeper into this concept, feel free to read our dedicated article on what knife HRC hardness really means.

Criterion Classic Western Knife Japanese Knife (first purchase)
Sharpening angle 20° to 22° per side approx. 15° per side
Typical hardness 54–58 HRC 53–56 HRC to start
Weight Heavier, thick blade Lighter, thin blade
Cutting effort More pressure needed Less pressure, cleaner cut
Maintenance More forgiving Hand wash + immediate drying recommended
Shock tolerance More robust Handle with care (avoid bones, frozen food, hard boards)


The Classic Trap to Avoid as a Beginner

Over the years, we see the same mistakes come back with new buyers. The most frequent, by far: wanting to specialise too early. Buying a Yanagiba to make sushi on Sundays, for example, before ever having handled a Japanese knife.

The Yanagiba is a single-bevel knife (sharpened on one side only), specifically designed to slice raw fish in a single pulling motion. It's a beautiful piece, but completely unsuited to 90% of what you cook daily: vegetables, meat, herbs. The same applies to the Usuba or Deba — specialist knives.

To get started, the rule is simple: one versatile double-bevel knife (sharpened on both sides, like a classic Western knife) is more than enough. No technique readjustment needed, and it's with this type of knife that you learn fastest — because you use it every day, for everything.

Which Knife to Choose to Start: Gyuto or Santoku?

Two knives compete for the title of ideal first purchase, and each has its own logic.

The Japanese chef's knife (Gyuto) is the equivalent of a Western chef's knife — finer and lighter. Its 20 to 24 cm blade for home use makes it the most versatile knife in existence: meat, fish, vegetables, herbs — it handles everything. It's the most cost-effective choice in the long run, since it remains relevant even as you improve.

The Santoku, with its shorter (17–18 cm) and wider blade, naturally guides the cut in a forward pushing motion. It's slightly more technically accessible for someone who has never held a fine blade, particularly on vegetables.

Our recommendation for getting started: if you have no experience with technical cutting, go for a Santoku. If you're already used to a Western chef's knife and simply want to feel the Japanese difference, go straight for a Gyuto.

At Kaitsuko, the Chef Tanaka collection is designed exactly for this first purchase: 5Cr15MoV steel at HRC 53–54, robust, accessible, easy to maintain and resharpen. It's the profile we systematically recommend to a customer writing to us about their first Japanese knife.

One Knife or a Small Set to Start?

Our consistent advice: don't buy a 7 or 10-piece set for your first purchase. The vast majority of knives in a large set stay in a drawer, simply because a beginner hasn't yet identified their real uses.

The most logical progression — which we observe with customers who later come back for other pieces — is to start with a Gyuto or Santoku alone, use it for a few weeks, then complement with a paring knife (Petty) for precision cuts: peeling, fine chopping, working with fruit.

If you prefer to start directly with a complete base at a better price than individual purchases, the 3-knife Chef Tanaka set or the 3-knife Kaito set (depending on budget) already covers the essentials of everyday cooking, with the same easy-to-handle steel foundation.

Stainless or Carbon Steel: The Most Important Choice After Shape

Once the shape is chosen, steel is the second decision that really matters. For a beginner, the answer is almost always the same: stainless steel.

Carbon steel offers exceptional sharpness and resharpens more easily, but it rusts if not dried immediately after use, and can stain slightly on contact with acidic foods like lemon or tomato. It's a steel that demands rigour and is better suited to a second or third knife, once good habits are established.

Stainless steel, like the 5Cr15MoV used in our entry-level collections, is far more forgiving of occasional inattention. That's what we recommend for a first purchase — time to build the habit of hand washing and immediate drying, before potentially moving on to a more demanding steel.

Mistakes to Avoid with Your First Japanese Knife

Beyond the trap of specialising too early, here are the most common mistakes we observe:

Underestimating the cutting board. A Japanese knife on a glass, marble or ceramic board will chip within weeks, even with a moderate steel. Always use wood or quality soft plastic.

Thinking "harder is better" for a first purchase. A very hard steel (above 60 HRC) cuts remarkably well, but it's also more fragile under lateral shocks and requires a suitable stone to resharpen correctly. For getting started, a more moderate steel is a wiser choice, not a cheap compromise.

Ignoring maintenance from day one. No Japanese knife, even entry-level, stays sharp without minimal care. Better to build good habits from first use than to have to catch up later.

Buying from a dubious website. Copies of Japanese knives are common online. Check reviews, transparency about the actual steel used, and the presence of a real customer service team.

Common mistake Why it's a problem The right reflex
Buying a Yanagiba or Usuba as a first knife Specialist knife, single bevel, demanding technique Start with a double-bevel Gyuto or Santoku
Cutting on a glass or marble board Chips the blade within weeks Use a wooden or soft plastic board
Aiming for steel above 60 HRC from the start More fragile under shocks, harder to resharpen Stay at 53–56 HRC for a first purchase
Not drying the blade after washing Corrosion risk, even on stainless steel Wipe dry immediately after every wash
Buying a large 7–10-piece set from the start Most knives go unused Start with 1 knife, then add later


How to Maintain Your First Japanese Knife

Three rules are enough for a first Japanese knife to last years rather than months.

Hand wash only, never in the dishwasher. Heat and aggressive detergents damage the blade edge and weaken the handle.

Dry immediately after every wash. Even stainless steel doesn't like staying wet for long.

Regular rather than occasional sharpening. For normal home use, a light pass on a honing steel before each use is enough to maintain the edge, and a full whetstone sharpening every two to three months preserves the original angle.

FAQ – The Questions We Get Asked Most About a First Japanese Knife

What is the best Japanese knife for beginners? A Santoku or chef's knife (Gyuto) in stainless steel around 53–56 HRC, like our Chef Tanaka or Kaito collection. Accessible, robust and easy to sharpen.

Do you need a very hard steel to start well? No. A steel around 53–56 HRC cuts very well and resharpens without specialised equipment. Steels above 60 HRC are relevant for a second purchase, once good maintenance habits are established.

How much does a good first Japanese knife cost? A quality entry-level Japanese knife in stainless steel typically starts around €50–70 per piece. That's a reasonable budget to test the experience before investing more.

Will an entry-level Japanese knife rust? No, stainless steels like 5Cr15MoV don't rust under normal use, as long as you dry the blade after each wash.

What blade size to choose for a beginner? A Gyuto between 18 and 21 cm or a Santoku of 17–18 cm covers the needs of a home kitchen comfortably. Blades over 24 cm are more suited to professional use.

Should you buy a complete set to start? No, it's not necessary. A single versatile knife is enough to begin. A 3-piece set makes sense if you already know you'll use a chef's knife, a Santoku and a paring knife.

In Summary: Where to Start

If you're still undecided after this article, here's the short version.

First step: a Santoku or Gyuto Chef Tanaka in 5Cr15MoV stainless steel. Robust, accessible, easy to maintain.

Second step, after a few weeks of use: add a paring knife (Petty) for precision cuts, or go directly for a 3-piece set if you prefer to have everything at once.

And above all: don't specialise too early. A well-chosen versatile knife will teach you more, faster, than a specialist piece you'll use once a month.
