I have drilled pencil size holes in shelves, walls and everywhere around workshop and try to remember to put pencils back in one after use - does save a bit of time.
Zebra Delguard propelling pencil (Zebra Pen Delguard Mechanical Pencil, Fine Point, 0.5mm, Black Barrel, Refillable, 1-Pack: Amazon.co.uk: Office Products) is also good -protects lead against snapping off and gives a good fine line
