That's a Honey Farm Designs Handmade Hybrid maple burl and resin handle with 25x68mm Two Band Finest Badger hair knot. Mounted knot is 25x54.
An Omega, put into a nice handle, is as fantastic as a brush can get. I bet @Jayaruh can fix you up. Here is a Jayaruh 400, with an Omega Pro 49 knot. I love this brush.
Very nice, I will look into that. I only have two brushes a Simpson Chubby 2 and a boar, the boar works quite well. I will probably get a silvertip also to have in my limited rotation. Sent from my SM-G960U using Tapatalk
And to see just how Big that one is, here it is with some more familiar brushes: From left: Truefitt & Hill (Simpson) Chubby 3, Kent H-12, the likely Rooney, a Simpson 58.
