Here is a pro barber boar brush with an all-metal handle. These handles are made out of copper and are then chromed. They are special ordered without the ring so that a larger knot can get into it. Loft height is similar to the B2, but removing the ring makes it longer. The effective loft is similar. It is a 27 x 57 mm boar professional brush made out of copper and then chromed. This is the same boar knot that is in the B8 brush. The effective loft is 47-51 mm from glue bump. Total weight is a hefty 145 grams.
