For a long time now I've wanted a Rubberset 400 brush. Loved the design of the handle and it looks just amazing, to me, when re-knotted. So, last week I finally found a 400-3 in a nice condition Condition Initially I had planned to have it replated/buffed, etc but the handle is actually so good that I might just leave it as-is and just have it re-knotted with a nice badger. As it looks now: Bottom: Size of the handle When looking at the 400's online I had a hard time really understanding the scale as most of them were not pictured alongside something with known dimensions. The very first thought that struck me when I opened the package was; "It is much smaller than I thought. This is perfect!" Here it is next to an SOC boar brush: The brush feels just fantastic when you hold it. Easy to get a good grip. Versions of the 400 As far as I know there are only 400-3's and 400-4's out there. The number supposedly indicated knot size (that part is detachable from the handle) but I must admit I don't know for sure so if anyone have more information I'd love to learn. Right now... I'm plotting and planning what knot to put into the handle and if I really want to/need to replate/buff the handle some. In the meantime it's just hanging out...waiting to be used... Other members of the 400-club I know there are at least 1-2 other 400-brush owners on this site. Post a photo or two of your brush here and what, if anything, you have done to it.
