My favorite pencil. Give them a try if you like mechanical pencils.Something I use this pencil for which is was likely never designed for:1. It makes a great depth gauge for measuring the depth of small holes, or other small features. I do this be extending the lead, and using the tip as a stop. Once done, just measure the amount of lead sticking out with a pair of dial calipers.
