It's one of the first questions every knife buyer hits: do you buy a single really good knife, or a whole matching set? Both are sensible — but they suit different cooks, and the "better value" answer flips depending on what you actually cook and how many blades you'll genuinely use.
The honest version is this: a single knife is usually the smarter first purchase, while a set is the better value per knife once you know you'll use them. Below we put real numbers to it using our own single knives and knife sets, then help you pick the right route.
Key takeaway
Buy a single knife if you want to try Japanese steel or upgrade the one blade you use most — you'll spend less and waste nothing. Buy a set if you're fitting out a kitchen from scratch or buying a gift: per knife it's far cheaper (our sets work out at roughly £25–£50 a blade versus £65–£95 bought singly), and you usually get matching handles, scabbards or a stand thrown in.
The value maths: what you really pay per knife
"Better value" only means something once you count the cost per knife you'll use. Buying in a set almost always lowers that number. Our Aiko Black Damascus range is the clearest example, because you can buy the very same knives one at a time or boxed together:
- A single Aiko knife costs £64.99–£94.99 depending on the blade (the 8" chef's knife is £84.99).
- The Aiko 5-piece set is £239.99 — about £48 a knife.
- The Aiko 9-piece set is £409.99 — about £45 a knife.
Buy five Aiko knives individually and you'd spend roughly £380; the 5-piece set saves you around £140. The same pattern holds across the range — our flagship Haruta 10-piece set is £499.99 (about £50 a knife, with a wooden scabbard for every blade), whereas the individual Haruta knives are £64.99–£89.99 each.
But there's a catch worth being honest about: a set is only cheaper if you use the knives. Pay £48 a blade for five and leave two in the drawer forever, and you've actually paid £80 each for the three you use. That's the whole decision in a sentence — which brings us to how to choose.
Which is right for you?
Buy a single knife if…
You're trying Japanese knives for the first time and want to feel the difference before committing. You already own decent knives and just want to upgrade the one you reach for most — usually a chef's or santoku. Or you do mostly one kind of prep (lots of veg, say) and a single Riku VG10 or santoku covers it. One excellent knife you use every day beats five you don't.
Buy a set if…
You're kitting out a kitchen from scratch and need a few blades anyway, you want everything to match and store neatly (most of our sets include scabbards or a magnetic stand), or you're buying a gift — a boxed set looks and feels far more generous than a single blade at the same kind of spend. If you'll use most of what's in the box, the per-knife saving is real money.

A quick word on care — it matters more with a set
Whichever way you go, Japanese steel rewards a little looking-after: hand-wash and dry your knives rather than putting them in the dishwasher, store them on a magnetic rack or in their scabbards rather than loose in a drawer, and keep them keen with a whetstone. The more blades you own, the more this adds up — so factor a few minutes of care into a set purchase. Our complete knife care guide walks you through it.
Frequently asked questions
Is it cheaper to buy a knife set or individual knives?
Per knife, a set is almost always cheaper. Our Aiko 5-piece set is £239.99 — about £48 a knife — versus roughly £65–£95 each bought individually. The saving is only real, though, if you'll actually use every blade in the box.
Which single Japanese knife should I buy first?
A santoku or a gyuto (chef's) knife handles roughly 80–90% of everyday prep, so that's the blade to start with. If you're unsure on length, see our guide to what size chef's knife to buy first.
Do I really need a whole knife set?
No. Most home cooks manage perfectly with two or three knives — a chef's or santoku, a paring knife, and perhaps a bread knife. A set makes sense mainly when you're fitting out a kitchen from scratch or buying a gift.
Are cheaper Japanese knives any good?
Yes. Our Riku knife starts at £49.99 yet uses the same VG10 Damascus steel as our pricier ranges — you're mainly paying more elsewhere for handle materials, finish and scabbards, not for a sharper edge.
What knives come in a Japanese knife set?
It varies by set. A compact set like the Haru 4-piece covers a chef's, kiritsuke, utility and paring knife; a full set like the Haruta 10-piece adds santoku, nakiri, bread and boning knives plus a scabbard for each. Always check the blade list before buying so you're not paying for knives you won't use.
