I use an old scope I "borrowed" from the Boatny lab when I was in college and I forget to take it back...
Jimrick makes a VERY good point regarding the need to have either experience to draw on or pictures to look at regarding a worn and unworn stylus. I'd wager that the vast majority of folks would not be able to tell whether the stylus was worn or not, even if they had the appropriate optics to see it clearly.
