This 1/2 inch watercolour swordliner brush is made from a blend of sable and is beautifully tapered with a very fine point.
These brushes are made in the U.K by the Rosemary Brush Co.
The beauty of this brush shape is that it allows you to taper your brush stroke from a thick line right down to a very fine line (without the tremble sometimes associated with a rigger) and you can get some fantastic loose effects when you twist the brush from side to side. One of the other advantages that watercolour swordliner brushes have over the traditional rigger brush for fine line work is that because the brush has a nice belly to it it does not run out of paint half way through a stroke like a rigger will.
Amongst other things I use these brushes for branch work and foliage on trees plus they are fantastic for rigging, telephone cables etc.
A versatile brush that any watercolour painter should not be without!
