Channel Knife

A channel knife is a small hand tool with a notched steel blade that cuts a narrow strip of citrus peel, about 3 to 5mm wide on the ones we use, in one long piece. The strip curls into a spiral as it comes away. It cuts the lemon spiral that hangs inside a Horse's Neck and the long peel that lines the glass for a Brandy Crusta.

About the Channel Knife

A Notch Sets the Depth of the Cut

The blade is a short strip of steel with a sharpened notch in it. Drawn across citrus peel, the notch lifts out a narrow strip a few millimetres wide and leaves a groove behind it.

Because the notch fixes how deep it cuts, the strip is mostly coloured zest with little white pith. Tilt the tool and it digs deeper, which is the usual way it goes wrong.

The Spiral Goes into the Glass First

Our Horse's Neck starts with the peel. Cut a whole lemon into one spiral, hang one end over the rim of the highball, then add ice so the cubes hold the spiral against the side. The cognac and ginger ale go in after.

The Brandy Crusta follows the same order in a coupe. The rim is sugared, the long strip of peel is curled inside, and only then is the shaken drink double strained in.

Cut in one steady pass, turning the fruit against the blade. A pause leaves a visible step, and a spiral in two pieces does not hang.

Three tools for citrus peel

Channel knife

What it cuts: One narrow strip, about 3 to 5mm wide on ours, that curls
Oil for expressing: Little
Used for: Spirals for a Horse's Neck or a Brandy Crusta

Y-peeler

What it cuts: A wide, flat strip
Oil for expressing: Plenty
Used for: Twists expressed over a drink

Zester

What it cuts: Several fine threads at once
Oil for expressing: Little
Used for: Zest scattered over or grated into a drink

A Peeler Gives More Aroma

A narrow strip holds little of the peel's oil. When a drink needs citrus oil misted across its surface, cut a wide strip with a Y-peeler instead.

That makes the channel knife a second citrus tool, bought once you start making drinks that call for a spiral.

Keep the Notch Clear and Sharp

Pith builds up in the notch, and a clogged notch tears the peel. Rinse it after each use and clear it with a cocktail stick.

Once the edge dulls, the strip comes away ragged and will not curl cleanly. The notch is too small to sharpen well, so replace the tool.

Using it

Using the Channel Knife

Usage

Cutting long, narrow spirals of lemon or orange peel: the spiral hooked over the rim of a Horse's Neck, and the strip that lines a Brandy Crusta. For a wide twist to pinch over a drink, use a Y-peeler instead.

Pro Tip

Wind a freshly cut spiral round the handle of a bar spoon and hold it for a few seconds before it goes into the glass. It tends to keep a tighter curl.

Professional Tips

Start at the stem end and turn the fruit against the blade, not the blade round the fruit.
Keep the pressure even. The notch sets the depth by itself.
Use a firm lemon. Soft fruit tears halfway round.
Cut the spiral before you build the drink, because it goes into the glass first.

Alternatives

Budget Alternative

A combined zester and channel knife. The notch is a simple shape, and while the edge is sharp it cuts a spiral as well as a dedicated tool.

Premium Option

A channel knife with a heavier handle and a replaceable blade. It sits steadier in the hand on a long cut; the spiral is no different.

Common Questions

What is a channel knife?

A small tool with a notched steel blade that cuts a narrow strip of citrus peel, a few millimetres wide, in one long piece. The notch sets the depth, so the strip carries little white pith. It is often combined with a zester on the same handle.

How do you make a lemon spiral?

Use a firm lemon. Set the notch at the stem end and turn the fruit steadily against the blade, so the cut runs round and down in one continuous spiral. Stopping leaves a step, and a strip in two pieces will not hang in the glass.

Channel knife or zester?

They cut different things. A zester lifts several fine threads at once, for scattering over a drink or grating into a syrup. A channel knife cuts one narrow strip that curls. For a wide twist to express over a Martini, use a Y-peeler.

What drinks use a citrus spiral?

In our recipes, the Horse's Neck, where a lemon spiral hooks over the rim of the highball and hangs inside it, and the Brandy Crusta, where a long strip of peel lines the coupe. In both, the peel is in place before any liquid is poured.

Can I use a peeler instead of a channel knife?

Yes, and our Horse's Neck and Brandy Crusta both allow one. A peeler cuts a wider, flatter strip that takes more care to keep in one piece, but it holds more oil. The channel knife gives the neater, tighter curl.

How do you make a citrus spiral hold its curl?

Cut it from a firm lemon and wind it round a bar spoon handle for a few seconds before it goes in. In a Horse's Neck, hang one end over the rim and then add the ice, so the cubes press the spiral against the glass.

Can you sharpen a channel knife?

Not easily. The cutting edge sits inside a small notch that a steel or a whetstone cannot reach properly. When it starts tearing the peel instead of cutting a clean strip, replace it; they are simple tools and widely sold.

How do you cut an orange spiral with a channel knife?

Our method: wash and dry a firm orange, hold it in one hand and set the notch near the stem end. Press in and draw the knife round the fruit in one slow, continuous turn, keeping the pressure even so the strip stays one width. Let it coil as it comes away, then hang it in the glass.
