Regarding the chosen knot, this is something we'll have to see.
A couple of shaves should provide a fairly clear indication on where the chosen bristles and knot stand.
As far as the handle is concerned, seriously, when I saw post #1 in the thread I thought Shavemac equipped this prototype brush with a mock one. Very hard for me to believe a company with so nice and functional handles would put out in the market its first synth model on what essentially is a Wilkinson handle copy.
The present red handle indicated in post #1 lacks flair, is too simplistic and aesthetically incomplete to bear the name Shavemac on it, even if the knot it carries is synthetic (i.e. cheaper than a knot with badger hair). Strictly speaking, the knot should be of Shavemac quality, the handle should be one of the handles that are widely used for Shavemac's badger hair knots, and the final product (the brush) should reflect the Shavemac design, craftsmanship and performance from top to bottom.
