Wüsthof Classic Ikon review: the bruiser of the rack
The German workhorse that does what a Japanese blade can't — and lasts a generation doing it.
What's right
- + Forged from a single billet of X50CrMoV15 — heft and balance you can feel through the bolster.
- + 20° edge geometry survives squash skins, chicken bones, and frozen butter without chipping.
- + Full bolster protects your knuckles when you're working tired.
- + A genuine generational tool — Solingen factory has been doing this since 1814.
What's wrong
- − Heavier than a Japanese blade — ten hours of brunoise will tire your forearm.
- − Thicker grind means it doesn't slice tomato skin as cleanly as a thinner blade.
- − 20cm is the sensible length — the 23cm sounds heroic and isn't.
There are two camps of working chef. There are the ones who love Japanese steel — thin, sharp, demanding — and there are the ones who love German steel, which is forgiving in the way an old leather jacket is forgiving. I’ve never met a chef who only owns one. The right kitchen has both.
The Wüsthof Classic Ikon is the German blade I’d buy if I could only buy one.
What forging gets you
A “forged” knife is hammered or pressed into shape from a single bar of steel. A “stamped” knife — most of what you see on Amazon under £80 — is cut from a sheet, like a biscuit. The forged knife is denser, with a continuous metal spine all the way to the heel and through the bolster, which is the chunky brass-like piece between the blade and the handle. You can feel the difference in the first second you pick it up: it sits in the hand like a tool that means it.
The Classic Ikon’s particular trick is the double bolster — there’s metal at the heel of the blade and at the back of the handle. That gives the knife a balance point right at the index finger when you pinch-grip, and a chunky counterweight against your palm. For three hours of breaking down a leg of lamb, that balance is the difference between a knife that helps you and a knife that asks you to lift it every cut.
What 20° edge angle gets you
Japanese knives like the MAC MTH-80 are ground to 15° per side. The Wüsthof is 20°. That five-degree difference matters more than it sounds.
A 15° edge is sharper out of the box and parts food more cleanly. It’s also more fragile. Try to lever a chicken thigh bone with a 15° edge and you’ll chip the blade in three places.
The Wüsthof’s 20° is rugged enough to take genuine abuse without chipping. I’ve used mine to crack open winter squash, split chicken backs, and once — by accident, in a fast-moving kitchen — break the metal staple on a vacuum-pack bag. The edge needed honing but not sharpening. A Japanese knife would have needed a thirty-minute repair on the stones.
What it isn’t
It isn’t a precision tool. If you’re slicing radish into translucent ribbons or breaking down a fillet of plaice, you want the MAC. The Wüsthof is fine at that, but “fine” is the wrong adjective for a £185 knife. The MAC is better at that.
The Wüsthof is built for the things the Japanese blade shouldn’t be doing. Sunday roasts. Squash and root vegetables. Bone-in proteins. Butchering at home. The stuff where a thinner blade would chip and a cheaper blade would bend.
The 20cm vs 23cm question
Wüsthof sell the Classic Ikon in 16, 20, 23, and 26cm chef’s lengths. Ignore the 23 and 26 — they were designed for restaurant kitchens with deep, two-foot boards and they’re awkward at a domestic counter. The 16 is too short for an adult to use as a primary knife.
The 20cm is the right answer for almost everyone. It clears a bell pepper end-to-end in one cut, fits a normal cutting board, and is short enough that the blade doesn’t whip when you’re moving fast.

Care
It’s German steel, which is to say more forgiving than Japanese — it can sit wet on a board for an hour without rusting, and it’ll survive a dishwasher cycle, even though you shouldn’t.
Hone it with a steel before each use, sharpen it on a 1000-grit stone every couple of months, and it’ll outlive you. Wüsthof’s Solingen factory has been making blades since 1814, and the knife you buy today is, dimensionally, identical to the one your grandfather might have bought in 1958. That’s not nostalgia. It’s a manufacturing process that doesn’t need to change.
Should you buy one?
If the MAC review convinced you and you can only spend £150 on one knife, buy the MAC. If you’ve got the MAC already and you’re hitting its limits — chipping the edge on a bone, struggling with a winter squash — buy the Wüsthof Classic Ikon. The two together are the only metal you’ll ever need to have on a magnet rack.
I priced this review at £185 because that’s the John Lewis list price as of April 2026. Wüsthof have a habit of running 20% off through their direct UK site twice a year (typically Black Friday and a “spring kitchen” sale in March). If you’re not in a rush, wait for one. Same knife, £148.
