I bought this brush which was unused several months ago. On my 70th birthday yesterday, I finally decided to use the brush. I knew someday that someone wouldn't be able to resist it so thought it may as well be me.
So how did it perform? It's an amazing brush. Far too big and heavy for regular use. The density of the knot ensured that it was relatively easy to control both the creation of lather and it's application. I painted it on, but I managed a bit of a scrub for the first pass before smoothing over. As expected, the tips are silky smooth.
I managed my usual three passes. Squeezing out what was left was a messy business - so much lather!
Using the brush was quite a novelty and I'm glad I did. But this isn't a practical brush. It's really a display piece. And that's what it will be. Perhaps I'll leave it in my cabinet and make a point of taking it out for my 75th - if I'm still here, then each 5 years thereafter. So when it's passed on it won't have had much use and might appeal to a collector!
