The building pencil better than usual?
Hi read, novice builders!
In this very brief material I would like to highlight this question - why it is better to use the building and why the pencil for marking materials not suitable conventional, office (student)?
The reasons are as follows:
Let's start with the obvious, and later move on to a very non-obvious reasons.
At first, used in the construction more rigid graphite, and therefore harder to break off the tip even on hard and porous objects.
For example, a building with a pencil handy rascherchivat gazoblok and construction are not traced and meters.
Secondly, Building a better pencil "smears" - leaves more bold, more noticeable mark without gaps.
Here's a good example: water pipe in the wall construction layout in pencil.
Thirdly, building pencil made oval. You know what? Yes, so it does not rolled on a flat surface as usual.
Whoever lost pencils, pens and markers at the construction site will understand me.
Do you know what the negative construction of a pencil?
The only disadvantage of it is that it can not erode by a sharpener for an oval. Come to the aid wallpaper knife.
