Unboxing of a Staedtler Mars Technico 780C Lead Holder Clutch Pencil & Carbon Leads, my first impressions of using and holding the pencil. This pencil was bought for the purpose of being a secondary thick line pencil for working with architecture/engineering/mechanical technical drawing.

Technical drawings are created with the use of various line types including thick and thin lines. Instead of having to change the lead form of one pencil again and again, I bought this second pencil to be formed as a thick line while my other pencil works as a thin line.

At one point I mention how the pencil struggles in the Staedtler Mars Carbon 502 lead pointer tub, however I found that I just needed to empty the tub. The pencil works with the tub sharpener just fine.
