Feather Forge Sapphire Knives: Which One Do You Need?
Feather Forge Sapphire is our best selling Feather Forge range rebuilt with a 67-layer Damascus blade, a 10Cr15CoMoV cobalt core at 60 HRC and a handle poured by hand from stabilised burl wood and sapphire blue epoxy. It comes in four shapes, an 8" Chef, a 7" Santoku, a 7" Nakiri and a 6" Utility, and four sets. Below is what each knife is built to do, which one suits the way you cook, and which set makes the most sense for your kitchen.
Every knife on this page shares the same blade and the same handle construction. What changes is the shape, and the shape decides everything: how the edge meets the board, which cuts feel effortless and which feel like a fight. Pick the right shape and even a good knife feels better.

What is Feather Forge Sapphire?
Feather Forge is the range most of our customers start with: hand-forged Damascus in the shapes a home kitchen actually uses. Sapphire is its first expansion. The shapes stay the same. The blade and, above all, the handle are new.
Each handle starts as a block of stabilised burl wood. Sapphire blue epoxy is poured around it by hand, one handle at a time, and left to flow and settle on its own. Once it has set, the handle is shaped with a slim neck at the bolster and a palm swell through the burl, then polished until the blue glows when it catches the light. A round brass mosaic pin sits flush in the angled butt.
Because the resin never settles the same way twice and no two burl blocks share the same grain, every handle is a one of one. The knife in the photos is an example. Yours arrives with its own pour.
What every Sapphire knife shares
- Blade: 67-layer Damascus with a fine, satin feather pattern. The layers are folded around the core for strength and a pattern that is different on every blade.
- Core steel: 10Cr15CoMoV, a cobalt-enriched stainless in the same class as VG-10, chosen because it takes a keen edge and holds it.
- Hardness: 60 HRC. Hard enough to keep a thin edge through months of prep, tough enough to live on a wooden board.
- Edge: Sharpened by hand, then inspected and oiled before it leaves us.
- Handle: Stabilised burl wood and hand poured sapphire epoxy, contoured for grip, finished with a brass mosaic pin. No two alike.
The four Sapphire knives at a glance
| Knife | Blade | Best at | How it cuts | Pick it if |
|---|---|---|---|---|
| 8" Chef | 8", curved belly, pointed tip | Almost everything: onions, herbs, meat, squash | Rocking and slicing | You want one knife that does most of your prep |
| 7" Santoku | 7", flatter edge, dropped tip | Thin, even slices of veg, fish and boneless meat | Push cuts and quick chopping | You like a lighter, shorter knife that chops straight down |
| 7" Nakiri | 7", tall rectangular blade, flat edge | Vegetables, from cabbage to paper-thin shallots | Straight up and down chopping | You cook a lot of vegetables and hate "accordion" cuts |
| 6" Utility | 6", slim and nimble | Trimming, portioning, fruit, cheese, sandwiches | Controlled, precise slicing | Your chef knife feels too big for the small jobs |
Sapphire 8" Chef Knife: the everyday all-rounder
If you only own one good knife, it should be a chef knife, and this is our best selling one. The 8" blade has a gently curved belly that lets you rock through herbs and garlic, a long straight section for slicing, and a pointed tip for the fine work around an onion root or a chicken joint.
What it does best:
- Dicing onions, peppers and carrots at speed
- Mincing garlic, ginger and herbs by rocking the blade
- Slicing steaks, roasts and brisket in long, clean strokes
- Breaking down squash, cabbage and other big produce
At 8" it is long enough to take on a whole melon or a joint of meat, but not so long that it feels like a sword in a home kitchen. For most cooks it covers nine jobs out of ten.
Sapphire 7" Santoku: fast, precise slicing
Santoku roughly translates as "three virtues": meat, fish and vegetables. Compared with the chef knife it has a flatter edge and a tip that drops down to meet the spine, so it is built for cutting straight down and slightly forward rather than rocking.
What it does best:
- Thin, even slices of cucumber, tomato and potato
- Portioning fish and boneless chicken
- Quick chopping when you want speed over a rocking motion
- Scooping food off the board with the wide blade
The shorter 7" blade makes the santoku feel lighter and more agile than the chef. Cooks with smaller hands, or anyone who naturally chops up and down, often find it becomes their go-to.
Sapphire 7" Nakiri: the vegetable specialist
The nakiri is a Japanese vegetable knife, and once you have used one on a pile of veg it is hard to go back. Its edge is completely flat, so the whole blade meets the board at once. Every cut goes all the way through, with none of the half-joined "accordion" slices a curved blade can leave behind.
What it does best:
- Shredding cabbage and lettuce
- Paper-thin slices of shallot, radish and onion
- Julienne carrots, peppers and courgette for stir fries
- Carrying chopped veg to the pan on its tall, flat face
Keep it for produce. The nakiri is not made for bones, frozen food or prying, and it is not a rocking knife. Used for what it is built for, it is the fastest vegetable knife in the range.
Sapphire 6" Utility: small jobs, total control
The utility knife fills the gap between a chef knife and a paring knife, and it is the one you will find yourself reaching for more than you expect. The slim 6" blade gets into places a big knife cannot and gives you fingertip control on the fiddly jobs.
What it does best:
- Trimming fat and silver skin from meat
- Slicing sandwiches, bagels and cheese
- Segmenting citrus and prepping fruit
- Halving shallots, cherry tomatoes and garlic
It is also the knife most people pair with a chef knife first, which is why the two make up our Core Duo.
Chef, santoku or nakiri: which do you actually need?
If you are choosing between the three bigger blades, start with how you cut:
- You rock the knife, and you cook a bit of everything: the Chef.
- You chop straight down and want something lighter: the Santoku.
- Most of your board is vegetables: the Nakiri, alongside a Chef for everything else.
Whichever you pick first, the Utility is the natural second knife. It covers every small job the big blades are clumsy at.
The Sapphire sets: which one is right for you?
Every Sapphire set costs less than buying the same knives one at a time, and every knife in a set has its own one of one handle, so no two in your block will match.
Sapphire Core Duo: 8" Chef + 6" Utility
The two knives that handle almost every job in a home kitchen. The Chef takes the big prep, the Utility takes the fine work. If you are replacing a drawer of tired knives, this is where to start.
Sapphire Trio: 8" Chef + 7" Nakiri + 6" Utility
The Core Duo plus the vegetable specialist. Built for cooks who eat a lot of plants and want every cut covered, from big prep to paper-thin shallots.
Sapphire Complete Set: all four shapes
Chef, Santoku, Nakiri and Utility: the right blade for every job and four one of one handles side by side. The set to buy if you want to do this once and properly.

Sapphire vs the original Feather Forge
Same best selling shapes, two different builds. Neither is a downgrade; they are different knives for different tastes.
| Feather Forge Sapphire | Original Feather Forge | |
|---|---|---|
| Blade | 67-layer Damascus | 73-layer Damascus |
| Core steel | 10Cr15CoMoV (VG-10 class) | AUS-10 |
| Handle | Stabilised burl and hand poured sapphire epoxy, 1 of 1 | Olive burl |
Prefer the classic look? The full Feather Forge collection has both.
Looking after a Sapphire knife
- Hand wash with warm soapy water and dry it straight away.
- Never put it in the dishwasher or leave it soaking.
- Keep the epoxy handle away from direct heat, like the edge of a hot pan.
- Oil the blade lightly now and then to keep the Damascus looking its best.
- Store it on a magnetic strip or in a block to protect the edge.
Treat it well and the handle stays glassy and the edge stays keen for years.
Feather Forge Sapphire questions
Is every Sapphire handle really one of one?
Yes. The epoxy is poured by hand around a block of stabilised burl, and it flows and settles differently every time. Your knife has the same burl and sapphire blue look as the photos, but its own swirl, depth and colour.
Which Sapphire knife should I buy first?
The 8" Chef. It handles most everyday prep on its own. Add the 6" Utility next for the small jobs, or buy both together as the Core Duo.
How does 10Cr15CoMoV compare to VG-10?
They sit in the same class. 10Cr15CoMoV is a premium stainless steel with added cobalt, hardened here to 60 HRC. It takes a very keen edge, holds it well and resists staining. Our VG-10 steel guide goes deeper.
Is a Sapphire knife a good gift?
It is one of the best we make. Every knife arrives in its own gift box, and because the handle is a one of one, nobody else will ever own the same knife.
Do I need a discount code?
No. The price you see is the price you pay. There is nothing to enter at checkout.
