sandstone is not harder than flint because sandstone breaks in to smaller pieces.
I am very sure that granite is much stronger and harder than sandstone.
rock salt and conglomerate
a sandstone would break more easily because a quartzite is harder. a quartzite is made of sandstone melted together by magma
Granite particles are interlocked as the minerals formed from the slow cooling of molten material. Sandstone does not have the same interlocking crystal system, and voids between particles are generally larger.
The individual sand grains are most likely quartz which is harder on the Mohs hardness scale than steel tools and implements.

No. Not at all.

of cors not stupid
Granite is more expensive as it is made under the earth (metamorphic rock) and harder to extract than sandstone which is a sedimentary rock
Flint is a common name for a form of sedimentary rock called chert, formed from microscopic siliceous (essentially quartz) skeletons of radiolarians. As such the hardness of chert is 7, which is slighly harder than glass and considerably harder than steel. If it will scratch glass it is likely to be flint. Flint is often mistaken for limestone or marble, which is much softer and will not scratch glass.
sarsen (a very hard type of sandstone) generic 'bluestone' - Welsh dolorite also a few other ingneous rock of volcanic origin micaceous sandstone (Altar stone) small amounts of limestone used in packing of uprights some 'geensand' - sandstone bedrock is chalk, flint is also present
"The two basic rocks found in the Mammoth Cave area are limestone and sandstone. Limestone is the "soft" rock (more water soluble) that is dissolved more easily by water. Sandstone and shale are the rocks that are on top of the cave. They are "harder" (less water soluble) and don't let the water soak into the cave." http://www.nps.gov/archive/maca/learnhome/cur_k3_cla.htm
A knapper is a person who shapes flint or other stone through the process of knapping, Knapping is the process of making stone tools, mainly flint, by hitting the flint in such a way to produce a sharp edge for cutting or scraping. The knapper would use a harder stone than flint in this process, this was called a hammerstone.
Neolithic people shaped stone using various techniques such as grinding, pecking, and polishing. They used tools made of harder stones such as flint or obsidian to chip away at softer stones like granite or sandstone, gradually forming desired shapes and edges. These stone tools were essential for activities like hunting, cooking, and building.
