Earlier this week, I met with an 'old school' craftsman who was installing a fitted kitchen in to a neighbours house. I needed to make some notes and was about to pick up his sharpened pencil, when he stopped me saying that I could not use his pencil! His pencil was used for marking out only.
The pencil was a standard Steadtler, nothing special, but it was tapered and sharpened to a very fine point.
This got me thinking.....
Are you aware that there are professional pencil sharpeners? See this you tube link for details.
Needless to say, I have been trying to perfect the technique, so far with only OK results.
