Single Bevel vs Double Bevel
What this is based on: published manufacturer specifications and retailer listings, cited on each product; the weight of professional and owner reviews across multiple retailers; and hands-on experience sharpening and cooking with knives of this type. We have not individually tested every model listed, we do not run instrumented sharpness testing, and we do not claim a test we did not run.

Why it steers
A double-bevel blade is a symmetric wedge, so the forces on each face cancel and the knife tracks straight. A single-bevel blade is asymmetric: the ground face pushes food away while the flat face slides past it, so the blade drifts toward the flat side as it descends.
In skilled hands that drift is the point. It is what allows a yanagiba to take a single clean slice off a block of fish, and what makes katsuramuki — peeling a daikon into a continuous sheet — possible at all. In unskilled hands it just means your onion slices come out wedge-shaped.
The urasuki, and why it complicates sharpening
The flat side of a single-bevel knife is not truly flat. It carries a shallow concave hollow — the urasuki — surrounded by a narrow flat rim at the edge and the spine. That hollow reduces friction and makes the knife easier to keep flat on the stone.
It is also a finite resource. Every time you lay the flat side on a stone you remove a little of that rim, and once the rim is gone the hollow reaches the edge and the knife needs professional work to restore. That is why single-bevel sharpening is mostly done on the bevel side, with only a few light passes flat.
Restoring a worn urasuki requires grinding the flat face back — a specialist job. This is the main reason single-bevel knives are not a casual purchase.
Handedness is not negotiable
A right-handed single-bevel knife has the bevel on the right face as you look at the blade with the edge down and the tip away. A left-handed cook using it gets the steering working against them on every cut.
Left-handed single-bevel knives exist, cost more, and take longer to source. If you are left-handed and want traditional Japanese knives, budget for that.
Which you should own
Double bevel, for essentially all home cooking. A gyuto, a santoku or a nakiri covers everything a home kitchen does, tracks straight, works in either hand, and sharpens with the standard technique on any ordinary stone.
Consider single bevel only if you break down whole fish regularly, you have somewhere to get it professionally maintained, and you are buying from a retailer who will tell you which hand it is ground for. Watch particularly for kiritsuke, which is sold in both single- and double-bevel forms under the same name.
The picks in detail
#1 · First Japanese knife
Tojiro DP Gyuto 210mm (F-808)
The default answer to 'my first real Japanese knife'. VG-10 at around 60 HRC in a plain three-layer build, at a price that makes the inevitable first chip survivable.
What it does well
- VG-10 at 59-60 HRC takes a genuinely fine edge and holds it far longer than a German knife at 56-58
- 1.9 mm spine and 43 mm heel make it thin behind the edge without being fragile
- Cheap enough that learning to sharpen on it is not frightening
Where it gives way
- Handle finish is functional and unlovely; some units need the bolster easing with sandpaper
- Stainless cladding is soft and scratches readily
- Nothing about the fit and finish will impress anyone
Skip it if: Anyone who wants the knife to be beautiful. The handle is a workmanlike composite with a stainless bolster and nothing about it is charming.
| Blade length | 210 mm (8.3 in) |
|---|---|
| Steel | VG-10 core, 13-chrome stainless cladding (san mai) |
| Hardness | 59-60 HRC |
| Heel height | 43 mm |
| Spine at heel | 1.9 mm |
| Weight | approx. 187 g |
| Handle | Western, laminated composite wood with stainless bolster |
#2 · The one stone to own if you only own one
Naniwa Professional (Chosera) 1000
The stone that does the most with one grit. Hard enough to dish slowly, soft enough to raise a slurry that tells you what the edge is doing.
What it does well
- Splash and go, but still builds a rich, informative slurry
- Fast enough to reset a dull edge, refined enough to finish on
- 20 mm of abrasive — years of use before it is spent
Where it gives way
- Expensive for a single grit
- Magnesia binder does not like being stored wet
- You will still want a finishing stone eventually
Skip it if: A tight budget. It costs more than a combination stone and gives you one grit.
| Grit | 1000 |
|---|---|
| Size | 210 x 70 x 20 mm |
| Soaking | Splash and go |
| Binder | Magnesia |
#3 · A knife you want to look at
Shun Classic 8" Chef's Knife (DM0706)
The Damascus-clad knife people actually buy. A 16-degree-per-side VG-MAX edge at 61 HRC, a D-shaped pakkawood handle, and a look that sells itself.
What it does well
- 16 degrees per side is a sensible factory angle — acute, but not so thin it chips on a carrot
- Handle geometry is genuinely comfortable in a pinch grip
- Kai's warranty and free sharpening service are real, useful things
Where it gives way
- You pay a significant premium over a MAC or Tojiro for the Damascus cladding
- The D-shaped handle is oriented for right-handed use
- Thin tip is easy to snap if you twist it in a squash
Skip it if: Left-handed cooks who dislike a D-shaped handle, and anyone who resents paying for 68 layers of cladding that do nothing for cutting.
| Blade length | 8 in |
|---|---|
| Steel | VG-MAX core, 34 layers Damascus cladding each side |
| Hardness | 61 HRC |
| Edge angle | 16 degrees per side |
| Handle | D-shaped pakkawood with stainless bolster and end cap |
| Warranty | Limited lifetime |
