When it comes to sketching, line quality is everything. To build up the desired thickness using ink, you can either switch between multiple pens or you can hit the same line repeatedly with the same pen, as Spencer Nugent has done above; if using pencil or a pressure-sensitive stylus on a digital device, you can hit the same line and/or press harder, as Michael DiTullo's done below.
So this currently-under-consideration-at-Quirky design proposal has me curious. Designer "HSingh" is pushing for a pen with an adjustable tip, whereby a dial in the barrel somehow alters the nib's width.
There's virtually no explanation for how the thing would work, but the question is: Would you guys use this to change line weights, or do you prefer the old-fashioned way? And does anyone remember having to swtich back and forth from like, five different Koh-i-Noor Rapidographs in design school?
