Metolius Solid Wood Brush
This brush remains a mystery to me since I can not find it in any of the Metolius catalogs. I have seen it sold in catalogs more of Europe than the United States, although it is still available to be purchased through many websites.
My guess is that it was first developed sometime c.2012
Razorback boars hair brush - Densely packed boar’s hair bristles for maximum cleaning with ribbed, ergonomic handle for excellent grip and knuckle clearance. Tapered bristles are longer at the front for increased longevity and a square head for better access into nooks and crannies.
Colors - black, blue, bright green
Size: 7" x ¾" (180 mm x 19 mm) c.2021
