So, this is a bit geeky but I was (well, still am) listening to a recording of Brahms Symphonies conducted by Wilhelm Furtwängler... what can I say, it is a really awesome performance and has superb sound quality for a recording made in... 1952. Then I got to thinking that wait a moment, the pens that are currently on my desk are all from that same era, some maybe even same year! ...and then you give a moment to think how well they still perform especially compared to modern pens and it really kind of blows you away. Pretty amazing actually.
