The KYVU B4 is a handmade black pocket comb, hand-sawn from a solid sheet of premium cellulose acetate — a plant-based material derived from wood pulp, never injection-moulded. Each comb is shaped, sanded and hand-polished to a smooth, classic glossy-black finish. At 12.9 cm and 14 g, it's a substantial pocket comb — small enough to carry, big enough for full, comfortable styling strokes.

Best for: everyday styling and detangling in one comb · all hair types · beard and moustache grooming · men & women · carrying in a pocket, bag or wash kit · travel and on-the-go grooming · anyone replacing a flimsy plastic pocket comb. Prefer a warm tortoiseshell finish? See the Tortoiseshell Dual-Tooth Pocket Comb (T4). Browse the full range in our Pocket Combs collection.

The B4's dual-tooth design puts two combs in one: the teeth change along its length, with coarse, wider-spaced teeth along one half for detangling and working through thicker hair, and fine, closely-spaced teeth along the other for parting, smoothing and finishing. One comb covers both jobs on any hair type — and works neatly through a beard and moustache too. Because it's hand-sawn rather than moulded, there are no mould lines, seams or sharp edges, just a smooth, gentle finish from the very first stroke.

Cellulose acetate has real advantages over ordinary plastic: it's warm to the touch rather than cold, it helps reduce static and frizz far more than a plastic comb, and its natural flexibility means it won't snap or crack the way brittle plastic does. Every tooth is hand-rounded so it glides without snagging or scratching the scalp.

Suitable for men and women, all hair types. Compatible with grooming products — pomade, wax, cream, oil, beard oil. Wipe clean with a soft, damp cloth; avoid prolonged soaking and direct heat. A durable everyday comb made to last for years rather than be replaced.

Frequently asked questions

What is cellulose acetate, and is it better than plastic?
Cellulose acetate is a plant-based material derived from wood pulp. It's hand-sawn from a solid sheet rather than moulded, so there are no seams or mould lines; it's warm to the touch, helps reduce static and frizz far more than plastic, and its natural flexibility means it won't snap like brittle plastic. It's also biodegradable.

How do I use a dual-tooth comb?
The teeth change along the length of the comb. Use the coarse half to detangle and work through thicker hair, then the fine half to part, style and finish — one comb for both jobs, on any hair type, and tidy enough for a beard and moustache.

Does the B4 come in another colour?
Yes. The same comb is available in a warm tortoiseshell finish as the T4 — choose classic black or tortoiseshell to suit your preference.

How small is the B4?
At 12.9 cm and 14 g, it's a pocket comb that still gives full styling strokes — small enough for a pocket, bag or wash kit, and durable enough to carry every day.
