I used a 29 year old boar knot this morning. I got this 1985 22mmx60mm Old Spice Barber Brush with my blue Old Spice mug. It appears to have never been used. I had cleaned it up and just put it on a shelf with the mug. This week I am using 7 different brushes over 7 days, so I put it into the rotation. I am not sure what I was expecting, but I was very pleasantly surprised! The bristles were very soft and the brush produced copious amounts of thick cushioning lather from the Stirling Spice soap. You can teach an old boar new tricks! It is no longer a “Den Queen”!
