Katana at £260 vs £610: What the Price Really Changes

A buyer asked us directly: "If a £260 katana already cuts tatami, why pay £610?" It is the right question, and the honest answer is that the extra £350 buys almost nothing in raw cutting ability. It buys finish, fittings materials and the level of polish.

This guide puts the two tiers side by side: steel, clay tempering and hamon, fittings (zinc alloy vs copper/iron), same (ray skin), tsuka-ito, polishing, saya and blade geometry. By the end you will know exactly where each pound goes, and which tier to buy depending on whether you cut, practise iaido or collect.

What is the real difference between a £260 katana and a £610 katana?

The difference is not the cutting: it is the finish. Both tiers share full tang T10 steel at ~1.0% carbon, clay-tempered. What separates £260 from £610: sculpted copper/iron fittings instead of cast zinc alloy, real ray skin instead of synthetic, hand-tightened ito, finer polishing and a premium lacquered saya.

Here is the point most sellers avoid stating clearly: a properly tempered T10 katana at £260 cuts rolled tatami, green bamboo and water bottles without complaint. The blade is the same base steel as at £610. The price progression happens almost entirely above the blade, in the koshirae (the set of fittings) and in the finishing work.

In practice, at ~£260 you are buying a functional cutting tool with decent fittings. At ~£520 to £610, you are buying the same level of cutting dressed in authentic materials, sculpted and assembled by hand, with polishing that reveals the activity of the blade. Both are full tang. Both are functional. One is a tool; the other is an object.

What does price change in the steel and tempering?

Very little. T10 steel (~1.0% carbon, oil-quenched) is available from about £250 to £280 and remains the same steel at £520. 1095 (~0.95% carbon) occupies the £315 to £375 tier. The clay tempering (tsuchioki) that creates the structural hamon is present in both tiers. Beyond T10, raw cutting ability plateaus.

T10 is a high-carbon tungsten steel. Oil-quenched after a differential clay coating, it produces a hard edge (around 58–60 HRC) and a softer spine that absorbs shocks. That combination is what makes a good cutting katana. You get it at £250 just as at £610.

1095, with ~0.95% carbon, is an excellent cutting steel that holds a very fine edge. In our catalogue, it occupies the quality middle: the Katana Kuro 黒, about £315, the Katana Yūga 優雅, about £340 and the Katana Kikumon 菊紋, about £375. At this price level, the steel is no longer the variable that rises; the finish starts to climb.

The hamon (刃文), the visible temper line, is structural from the £260 tier if the steel is clay-tempered. It is not a decorative trick. The difference at £610 is not the existence of the hamon but the fineness of the polish that brings it out (see the polishing section below).

How do the fittings of a £610 katana differ?

This is where most of the £350 goes. At £260: tsuba, fuchi and kashira in cast zinc alloy, soft motifs, synthetic same. At £520 to £610: sculpted and patinated copper or iron fittings, real ray skin (same) in a full panel, a choice of tsuba and menuki. The fittings last longer and age better.

The zinc alloy tsuba (鍔, guard) of a £260 katana is cast in a mould. It protects the hand and secures the assembly, so its function is fulfilled. But the reliefs are softened by casting and the material does not develop a patina. On a £520 to £610 katana such as the Katana Tonbo トンボ, about £520, the iron or copper tsuba is worked: crisp reliefs, precise openwork (sukashi) and a patina that evolves over time.

The same (鮫, ray skin) under the tsuka-ito also changes. At £260 it is often synthetic or a partial strip imitating the grain. At £610 it is real ray skin in a full wrap, with the natural central knot visible. Authentic same creates greater friction, which stops the ito slipping under the repeated stress of cutting, and it lasts better over time.

The fuchi (縁) and kashira (頭), the collar and cap of the handle, follow the same logic: cast zinc at the lower tier, sculpted copper or iron at the upper tier. On pieces at £610 and above, such as the Katana Ginga 銀河, about £835, the whole koshirae is coordinated and the choice of menuki (目貫, the ornaments under the ito) is part of the value.

Do the tsuka-ito and polishing justify the price gap?

In part, yes. The tsuka-ito of a £610 katana is sewn and tightened by hand, tighter and more even, with better-formed folds (hishigami). The polish moves from a functional finish to a finer polish, sometimes hadori or hasori, which reveals the activity of the hamon. That is human labour time, and it is what you pay for.

The tsuka-ito (柄糸, the handle wrap) at £260 is correctly tightened, often with the help of tools, and does its job. At £520 to £610 it is hand-tightened: the tension is stronger, the diamonds (the hineri-maki pattern) are more even, and the internal paper folds (hishigami) give a crisp, lasting relief. A hand-tightened ito does not loosen after a few months of use.

As for polishing, this is the most visible difference to the trained eye. A £260 katana receives a functional polish: the edge is sharpened, the blade is clean, the hamon appears. A £610 katana receives a finer polish, sometimes with a hadori finish (a whitened band that highlights the hamon) or hasori. This polish brings out the nie and nioi, the crystalline structures of the temper line, with a contrast the lower tier does not reach.

Blade geometry benefits too: on the premium pieces, the niku (the "flesh" of the blade, its convexity), the shinogi (the ridge line) and the kissaki (the tip) are refined with more care, which improves the evenness of the edge and the balance in the hand, a real plus for iaido.

The item-by-item recap. Full tang in both tiers. Steel and tempering change little; fittings, same, ito, polish and saya account for most of the price gap.

Which katana should you choose at each budget tier?

At £175 to £280, aim for full tang T10 for cutting. At £315 to £375, 1095 offers a finer edge and an intermediate finish. At £445 to £835, you are buying the copper/iron fittings, authentic same and premium polish. Choose the tier by your use, not by prestige.

Frequently asked questions

What is the real difference between a cheap katana and an expensive one?

Between a katana at about £260 and one at about £610, raw cutting ability changes little: both tiers can use full tang T10 steel at ~1.0% carbon, oil-quenched. What really changes is the finish. At £260 you have cast zinc alloy fittings, synthetic same and a correctly machine-tightened tsuka-ito. At £610 you get sculpted copper or iron fittings, real ray skin (same), a sewn, hand-tightened ito, finer polishing (sometimes hadori) and a premium lacquered saya. The extra £350 buys finish, fittings materials and polish, not a blade that fundamentally cuts better.

Does a £610 katana cut better than a £260 katana?

Not significantly. A properly clay-tempered full tang T10 katana at £260 already cuts rolled tatami, bamboo and water bottles without difficulty. Beyond T10, raw cutting ability improves little. A £610 katana brings more careful polishing of the blade geometry (the edge is refined more finely by hand), better evenness of the edge, and often a better-balanced weight distribution for iaido. But if your only criterion is "does it cut", the £260 tier already says yes. You pay the premium for perceived quality, fittings longevity and aesthetics, not for transformed cutting performance.

What is real ray skin (same) and why does it cost more?

Same is the ray skin that covers the tsuka (handle) under the tsuka-ito. Its granular surface creates friction that stops the ito slipping during cutting. On a katana at ~£260, the same is often synthetic or a partial strip imitating the grain. On a katana at £520 to £610, it is real ray skin in a full wrap, with the characteristic central knot visible. Real same costs more because it is a natural material, cut and fitted by hand, and it lasts better over time under the repeated stress of ito tightening. Functionally, it improves grip and handle durability over thousands of cuts.

Are zinc alloy fittings really worth less than copper or iron?

Structurally, a cast zinc alloy tsuba on a £260 katana does its job: it protects the hand and secures the assembly. The difference lies in the material and the detail. Zinc alloy is cast in a mould, so motifs are softer and less defined. Copper and iron, used on katana at £520 to £610, are worked and sculpted: the reliefs are crisp, the patina evolves over time, and the weight gives a better feel in the hand. Iron can also be pierced (sukashi) with greater finesse. You are not paying for better protection; you are paying for a better material, a lasting sculpted finish and an authentic look.

Is the hamon on a £260 katana a real hamon?

Yes, if the katana is T10 steel with clay tempering (tsuchioki). The hamon of a £260 T10 is a real, structural temper line, the result of differential cooling between the hardened edge and the softer spine. It is not an acid-etched or painted pattern. What changes at £610 is the refinement of the polish that shows off the hamon: a hadori or hasori polish brings out the activity (nie, nioi) of the temper line with more contrast and sharpness. The hamon exists at £260; at £610 it is revealed more finely. Beware of overly regular, whitish hamon below about £130: those are often etched, not tempered.

Should you spend £610 on a first katana, or is £260 enough?

For a first katana, £260 is enough in the great majority of cases. A clay-tempered full tang T10 at ~£260 covers beginner iaido, light to moderate tameshigiri, suburi and display. Move up to £435 to £610 only if a specific criterion justifies it: you practise regularly and want copper/iron fittings that last years without play, you are a collector and aesthetics matter as much as function, or you want a premium lacquered saya and authentic same. Many buyers start at £260 to £350, practise for a year, then invest in a piece at £520+ once they know what they are looking for. There is no shame in starting at the functional tier.

Conclusion

• The difference between a cheap and an expensive katana is not the cutting: it is the finish. Clay-tempered full tang T10 is the same base steel at £260 as at £610.
• The extra £350 buys sculpted copper/iron fittings instead of cast zinc alloy, real ray skin instead of synthetic, hand-tightened ito, finer polishing (sometimes hadori) and a premium lacquered saya.
• At £260, buy for function: the Katana Inazuma at about £280 in T10 cuts everything a beginner will ask of it. At £520, the Katana Tonbo brings collector-grade fittings and polish.
• Choose the tier by your real use (cutting, iaido, collecting), not by the price shown. The £260 tier is nothing to be ashamed of; it is a genuine functional tool.
