Synthetic vs Kolinsky Sable Brushes: Which One Do You Need?

This is a question every miniature painter runs into sooner or later: is Kolinsky worth the money? A hundred-crown synthetic brush versus a Kolinsky sable costing several times more — is there really a difference, or is it just marketing aimed at people with an oversized hobby budget? The answer is more complicated than a simple yes or no — and it depends on what you actually want from a brush.

This article walks through both types of brushes from the ground up: what they're made of, how they behave with different techniques, when synthetic is enough, and when Kolinsky genuinely changes the outcome of your work.

Synthetic and Kolinsky — what are they, exactly?

Synthetic brushes

Synthetic brushes are made from man-made fibers — most commonly nylon or polyester. Manufacturing technology has moved on a great deal over the past twenty years: modern premium synthetics behave considerably better than the cheap synthetics you'd find at a drugstore. Today's fibers are engineered to mimic the triangular cross-section of natural hair and achieve a similar snapping effect.

Kolinsky sable

Kolinsky is natural hair from the tail of an animal called Mustela sibirica (a type of weasel), specifically from the tail, where the hair is at its best quality. It originates from the Siberian region, where hunting was traditionally concentrated — today it comes mainly from areas like Taymyr in northern Russia, where the climate is harshest and, as a result, the hair is at its toughest.

Kolinsky isn't a single material — it's a spectrum of quality depending on origin, the part of the tail it comes from, and how it's processed. Scale75 Kolinsky Tajmyr names its region of origin directly in the product name, while Winsor & Newton Series 7 is famous for hand-selecting and binding hairs under a microscope.

A note on terminology: The word "sable" on a brush label doesn't automatically mean Kolinsky — there are various types of sable and their hair. Kolinsky sable is a specific type with particular properties. Always look for the explicit label "Kolinsky" or "Kolinsky sable," not just "sable."

Three properties that actually matter in a brush

When comparing synthetic and Kolinsky, three specific properties are relevant — everything else is largely a matter of personal preference:

Snap (spring)

The brush's ability to return to its original shape after every stroke. A brush with good snap is predictable. Without snap, the brush "splays out" and you have to actively correct it, reshaping the tip yourself.

Advantage: Kolinsky
Tip

The ability to hold a sharp point. This is what determines precision in detail work — eyes, fine-line highlights, delicate glazes, and transitions. Kolinsky holds its point longer and better; premium synthetic comes close, but not all the way there.

Advantage: Kolinsky
Paint capacity (belly)

How much paint the brush can hold in its belly. Greater capacity means fewer interruptions to re-dip the brush, plus a more even paint application. Thanks to its fiber structure, Kolinsky naturally holds more paint than a synthetic brush of the same size.

Advantage: Kolinsky
Wear resistance

Synthetic holds up better under rough use — drybrushing, stippling, working with coarser paints (say, metallics or oil paints). Kolinsky is more prone to damage from improper use and needs more careful maintenance.

Advantage: Synthetic
Resistance to oil paints

Modern synthetic holds up excellently against oil paints and thinners (like White Spirit). Kolinsky is fairly sensitive to harsher cleaning agents and certain mediums.

Advantage: Synthetic
Price and availability

Good-quality synthetic is generally much more affordable than a line of Kolinsky brushes. It's worth thinking about what you'll actually use the brush for, but as a general rule (and for the price alone) we'd recommend it as a starting point.

Advantage: Synthetic

Which technique calls for Kolinsky — and where synthetic is enough

Technique Recommendation Why
Base coating Synthetic A large area, a simple stroke — snap and tip aren't all that critical here. Synthetic handles base coating perfectly well, and there's no need to risk an expensive Kolinsky brush on it.
Washing / Shading Synthetic A wash is a thin paint that flows on its own. Neither snap nor tip really come into play — you just need a soft brush.
Drybrushing Dedicated drybrush brush An abrasive technique that will ruin any good brush. Never use Kolinsky for drybrushing — only a stiff brush made specifically for that purpose.
Layering and highlighting Premium synthetic or Kolinsky Tip precision starts to matter for edge highlighting. Premium synthetic works great here; Kolinsky gives you even more control.
Glazes and blending Kolinsky or premium synthetic Smooth glazes need good snap and paint capacity. Cheap synthetic falls short here — Kolinsky or premium synthetic will make a noticeable difference.
NMM and fine detail Kolinsky The most demanding technique in terms of tip and snap. A Kolinsky in sizes 0 and 1 is the best investment here — the tip holds up even after an hour of precise work.
Painting skin and faces Kolinsky or premium synthetic Faces are the most eye-catching spot on any miniature. Tip precision directly affects the result here — it's worth reaching for a better brush.

Brush care — Kolinsky demands more respect

One argument against Kolinsky is the care it requires — and it's a fair one. Kolinsky sable is a natural material that reacts to poor handling much more sensitively than synthetic.

  • Never soak past the ferrule (the metal part at the brush's base) — paint trapped in the ferrule spreads the bristles apart, and the brush loses its tip permanently. This applies to both types, but Kolinsky is more sensitive to it.
  • Never leave it standing in water — bent Kolinsky bristles can't be fixed. After rinsing, always lay the brush flat or store it tip-up.
  • Clean with soap after every session — a gentle brush soap (or, in a pinch, ordinary hand soap) removes leftover paint and reshapes the tip. For Kolinsky, this is a mandatory routine, not an optional one.
  • Store the brush with a protective cap — a plastic cover or a travel tube protects the tip from damage when you're on the move.
Kolinsky and drybrushing don't mix. The abrasive dry-brush technique will ruin a premium Kolinsky in a single session. Always keep a dedicated drybrush brush on hand — and never confuse it with your beloved Kolinsky.

When to upgrade — and when not to

Stick with synthetic if:

You're just starting out and want to learn the basic techniques without a financial commitment. You mainly paint larger armies to tabletop quality. You tend to be rough on your brushes or forget to maintain them. You want a vegan alternative.

Upgrade to Kolinsky if:

Synthetic is frustrating you during detail work — the tip falls apart partway through a line. You're trying advanced techniques like NMM, blending, or glazes on miniature faces. You're willing to put in the time for proper care after every session.

Try premium synthetic if:

You're not sure whether Kolinsky is for you — premium synthetic is a great middle ground. Noticeably better than cheap synthetic, with no need for intensive care, at a reasonable price.

Use both:

Most experienced painters work with both types: synthetic for base coating, washes, and drybrushing — Kolinsky for details, glazes, and finishing touches. You don't have to pick just one.

Summary — is Kolinsky worth it?

  1. For beginners: no. Learn the techniques first — then invest in a better tool.
  2. For more advanced painters: it depends on the technique. NMM, blending, faces → yes. Base coating and washes → no.
  3. We recommend Kolinsky once synthetic starts frustrating you during detail work — not before.
  4. Care is mandatory — neglect a Kolinsky and you'll wear it out faster than a cheap synthetic.
  5. Drybrushing always means a dedicated brush — a drybrush brush, never Kolinsky or even a good synthetic.
  6. Combining both works best — synthetic for rough work, Kolinsky for the finesse.
