I came here to say this. I have a rotring 600 mechanical pencil with non-retractable tip, and it bends if you even look at it funny. It can be straightened again if you insert a sewing needle so it was not a big deal, but it was unexpected how easy it bends.

Heck, I have to treat it even more carefully than my smartphone. Not that I treat it rough or anything, but I have to be very conscious of where I leave it, lest it rolls off and falls off a height of a few centimeters.

Other than that I don't regret buying it, it's been a few years and it still feels nice to use.
