With a pencil of tenth hardness, with a good sharpening, it seems possible to perform a biopsy. Such a small biopsy. The pencil of the tenth softness runs on paper with a clearly distinguishable twist and makes you remember the joke about the cat and the swallow - only the ears came to the balcony. Gifted by a good modern carpenter scissor for hunting the low-flying females of xenomorph in the marriage period is so sharp and heavy that they can not have those pencils, but if desired, immediately in the salad with slices. Sketch notes with a good dense paper covered the table box. Literally covered under the cover.
