In regards of the OP question about the knickers.
I prefer a knife line because it’s deeper and better defined compared to the line produced by the plane knickers (the Stanley 13-50 has spear shaped knickers btw).
Also the knife line is usually already there as a reference to setup the plane.
On top of that you have to make sure that the knickers are sharp enough when needed and this adds quite some extra time on the tool setting and apparently one or two more cutting edges that have to be regularly maintained.
On the other hand everyone (?) has a sharp marking knife close to hand and a square.
And now a bit of rant
@Inspector: The example with Ferrari (and any car maker in general) is completely irrelevant. All new cars have patented designs and they are replaced by new models way before the patent expires. When the patent expires (industrial patents last 20 years) the market has changed so much that it’s pointless to produce an almost exact copy of an old car.
On other goods though like medicines, tools, food products (if I remember well corn flakes, instant coffee etc. were once patented) when a patent expires many other companies are introducing their own versions at lower prices since the high cost for R&D doesn’t apply to them.
In the past Record tried to extend the patent of their woodworking vices by making changes to the design while at the same time it copied the Stanley planes.
I have noticed recently a bunch of various Tite-Mark style marking gauges, from Chinese manufacturers, in the market and that makes me think that the Tite-Mark’s patent has expired, since there were no similar marking gauges offered in the past.
Also the Chinese manufacturers (the ones who strive to make quality tools) don’t try to fool anyone that they are buying LN. Their products are clearly branded and they just claim that they are as good as the LN ones (or almost as good). I have two block planes made by Quangsheng and the built quality and attention to detail are top notch (I still prefer the traditional carbon steel for edge tools though).
