Balsa wood. You can shape it easily with a knife.
There are quite a few, one is phosphorus in its allotrope known as white phosphorus.
Lithosphere :)
The hardest layer of the Earth is the inner core, consisting mainly of solid iron and nickel. Followed by the outer core which is liquid iron and nickel. The mantle is softer than the core but still solid, made up of hot, flowing rock. The crust is the Earth's outermost layer and the softest of the four layers.
diamond is the hardest and graphite is the softest
Talc is the softest mineral. The Mohs hardness scale goes like this, from softest to hardest: 1. Talc, 2. Gypsum, 3. Calcite, 4. Fluorite, 5. Apatite, 6. Orthoclase Feldspar, 7. Quartz, 8. Topaz, 9. Corundum, 10. Diamond.
The softest wood is yucca wood, from Arizona. The softest wood used in woodworking is pine.

Talc is the softest mineral on Earth, with a hardness of 1 on the Mohs scale. It is commonly used in baby powder and cosmetics due to its softness and smooth texture.
Some of the softest woods include balsa, cedar, pine, spruce, and fir. These woods are preferred for projects or crafts where ease of cutting and shaping is desired.
The softest place on Earth is considered to be the Belum Caves in India, which are made of limestone and shale rock formations. These caves have unique geological features that make the surfaces soft to the touch.

C'mon. Diamond is the hardest mineral on Earth.
In general, the density of a timber (in kg.m3) is a good indicator of the quantity of material in the timber. [Of importance in selecting firewood.]Balsa Wood Ochroma pyramidale is a well known wood that is quite soft.In New Zealand, Pate, Schleffera digitata is a very soft wood, of similar properties to Balsa.
