The mineral is rather sectile, and consequently was earlier known as corneous lead.

It has a metallic luster, a lead-gray color, and is sectile like lead.

Thallium is extremely soft, malleable and sectile enough to be cut with a knife at room temperature.

Metals and paper are sectile.

They have two parallel locules with farinaceous, sectile pollinia.

It breaks with an irregular to conchoidal fracture and it is somewhat sectile.

Relatively few minerals are sectile.

Minerals can be described as brittle, ductile, malleable, sectile, flexible, or elastic.

The micaceous crystals are flexible and slightly sectile with a hardness of 2-2.5 on the Mohs scale.

It is sectile, with a fibrous fracture, and thin laminae parallel to the cleavage plane are flexible.

Its lustre is adamantine, vitreous and resinous, and it has conchoidal, brittle and sectile fracture.

All four crystalline varieties are sectile in that they can be easily cut, will peel (particularly selenite crystals that exhibit mica-like), and like all gypsum varieties, can be scratched by a fingernail (hardness: 2 on Mohs Scale).
