Uzukuri are natural fibre brushes tightly bound with cotton twine. They are traditionally used to refine finishes on furniture, panelling, sculptures and ornaments.
The set of three brushes includes a coarse brush made of bound thatching sedge, a medium brush of tampico fibre, and a fine brush of tightly compressed horse hair.
Through regular use the brush will abrade and wear, reducing the bristles' length. To effectively lengthen the brush, the binding is cleverly wound and can be pulled firmly from the middle of the brush to reveal more bristle.
The brushes work by scrubbing out the soft part of growth rings in typically plain-sawn (slabbed) boards. This provides an alternative when search for a raised-grain finish that doesn't require burning of the surface. Highly figured and quartersawn timber may be difficult to work with the uzukuri as the high density of growth rings impedes the natural fibres from doing their work.
The fine horsehair brush can be used to refine cured or dried finishes.
Each brush in the set measures 180mm long by 30mm diameter.
