Remember this?
Hehe! I am really giddy about this ...
... and one with a dark brown interloper at the side:
As for the brush, the knot itself is not as soft as Muhle, let along Plisson/Plissoft but it is related to the Plissoft in terms of appearance and how it is dyed. Consider it a lesser quality Plissoft and with that, it is actually more authentic. Immediately, it felt like a silvertip badger - that soft of slightly scratchy/grabby tips that silvertip has, gel-tips I've heard them called. It also has a sort of vintage feel, like when you get a vintage knot and it's dry feeling, possibly a little brittle until you get it in water and get some soap on it.
In use, the brush loads up effectively and is a joy to use. The loft is just right for good backbone and much less springiness than many synthetic knots. Many synthetics get around this by reducing the springiness in the fibre, which equates to a soft, floppy knot in use - Plisson, for example. Muhle got that compromise much better. This knot feels quite different to both and as I said above, it does actually feel more like a real badger in use.
For comparison, the brush on the left (the dark brown Deco brush) has a Muhle Silvertip Fibre knot.
@Darkbulb tagged in, as he specifically requested a picture of the kit together.
