Vegan synthetic sword/dagger liner for long fine lines, foliage and expressive strokes — thin to thick from one brush.
A sword liner (also called a dagger) has a long, angled head that tapers from a full ferrule down to a fine point, with one long working edge. It started life as a signwriter's brush, built to pull long, flowing lines that shift from thin to thick — and that heritage is exactly why artists still keep one in the jar.
This one is built from Rosemary & Co's Ivory synthetic, described by the maker as a cross between the feel of nylon and hog bristle. Firmer than a soft watercolour synthetic, it gives you real control over the line while still springing back to a clean edge. Like everything Rosemary & Co make, it's handmade in Cowling, Yorkshire, by a family firm that's been at it since 1983.
Made for oils, acrylics, gouache and water-mixable oils. The jobs it earns its place on: long grasses and reeds, tree branches and distant canopies, flower stems, petals and leaves, ripples on water, ship rigging and wires, hair, fur and whiskers — plus hand lettering, calligraphy and pinstriping.
What makes this brush special
A full belly holding a big reservoir of paint, tapering to a needle-sharp point along one working edge. Dip the tip and it draws hair-fine lines; lay the edge down and it sweeps broad, so the width shifts thin to thick as you roll the angle and pressure. The Ivory fibre is firm enough to control the line and springy enough to snap back without splaying. That long belly keeps a line flowing instead of running dry halfway.
Medium compatibility
Oil
Acrylic
Best with properly thinned acrylics, especially for detail and glazing.
Gouache
Handles opaque water-based paint when thinned to a brush-friendly consistency.
Great for
- Long, continuous lines that don't run dry — grasses, reeds, branches and rigging
- Lines that taper thin to thick in a single stroke, for movement and expression
- Botanical and landscape detail — stems, petals, leaves, ripples, hair and fur
- Hand lettering, calligraphy and pinstriping
Technique & use
- Detail Work
Less ideal for
- Consistent, even lines with no learning curve — a rigger is easier for that
- Solid coverage or broad fills — reach for a flat or a round
- Painters who want a general-purpose brush; a sword liner is a specialist tool

How we measure a brush
A visual guide to the measurements shown in the size chart above.
These are the same measurements shown in the size chart above. Brush sizes are not standardised across brands, so use these dimensions when comparing brushes within a series or between manufacturers.
- Tuft Length
- The visible length of the brush hairs, measured from the ferrule to the tip.
- Belly Diameter
- The widest point of the brush head. On round brushes, this is the widest part of the belly.
- Total Length
- The full measurement from the tip of the brush to the end of the handle.
How to care for your brush
Thin your paint to a flowing, ink-like consistency — it's the single biggest difference-maker for clean long lines. Dip just the tip for hair-fine work, or load the whole edge for broad sweeps. Let the shape do the work: pull the stroke and roll the angle rather than forcing it. Rinse thoroughly after use and reshape the edge while damp, then dry flat or tip-down. Clean acrylics promptly, before they set.
