Shaving Brush Handle
Having been a wet shaving enthusiast for several years, I decided to upgrade to a higher-quality brush. Silver tip badger hair is considered top-of-the-line, boasting soft yet springy hairs that are dense and retain the ideal amount of water.
Given the premium price of silver tip brushes, I opted for a DIY approach and ordered three knots from China—one for myself and two to sell to friends to cover the project's cost.
This brush features a turned curly maple handle. After shaping, Danish oil is applied to accentuate the wood's figure, followed by several coats of wipe-on poly to protect the brush in the damp environment it will be used in. Finally, the knot is secured with two-part epoxy, ensuring the brush is ready for many years of use.

luxury of feel and water retention. One knot is for myself, the
other two I plan to sell to fund the hobby. All badger comes from

The brush handle slowly emerges from the wood. I wasn't following a
set pattern other than my concept sketch, the shape evolves until
I am happy with the proportions and lines.

Parted off the stock and mounted on a jam chuck. This allows you
to sand the bottom and apply the final finish. I chose CA glue
applied in about a dozen thin coats for durability.
