I'm worried about putting it in my pocket.** A: It does not retract. I've got three of these for each jacket I wear so I don't worry about forgetting to take a pencil. So far no problems with the tip... **Q: is the body and cap a metal material** A: No the body and eraser cap are plastic material. However the grip, the end cap, and the lead sleeve seem to be metal. **Q: Do you need to buy a special kind of lead for it?** A: Any 0.5mm lead will work, but the specific Kurotoga lead is softer on the outside and is purportedly more effective with the mechanism. For very dark writing, I prefer Neox lead but it can smudge/smear a little. My second favorite is Ain Stein lead, which almost never smudges and lasts a little longer (not quite as soft as Neox). **Q: How durable is this? I am a graduate student in EE and math and break so many of the best mechanical pencils from staples and other office stores.** A: I actually bought this mp to add to my mechanical pencil collection. I now have about eight mps, all different. Therefore, I could not provide any info regarding its durability. I can say that this is a beautiful, finely crafted instrument. It may be the best in terms of appearance. I really don't think you would go wrong if you selected this one.
