Just FYI, for people who write a lot with mechanical pens, check out the Kuru Toga line with rotating lead engine. Every time you lift up your pen the lead rotates slightly which keeps your lead relatively sharp to a point. They are also very affordable at <$20 on amazon.
Just a note, they are inexpensive so despite some of them looking like metal they are light and plastic. But they seem high quality and dont break easily.
@frayoshi Its not actually my main writing tool as I tend to use fountain pens. I also have some very nice higher end metal mechanical pencils I prefer for other features. But as an every day pencil you dont mind loosing it would be my top choice and its great.
@frayoshi Also in general I prefer the smallest lead I can get. Usually thats 0.5mm or 0.3mm. But with the rotating lead engine I find thicker ones work well.
