Hardekool sanded to around 600 grit, and finished off in Danish oil. This brush fits in between a short and a long handled brush and is surprisingly comfortable, while still allowing for more hand movement instead of wrist movement. The dense wood weighs in at 64 grams, 125 mm high, with a 21 mm Best badger knot set at a 58 mm loft. Very little, or if you prefer no maintenance is required for this brush.
