Short description of error
The sculpt tool icons are counter intuitive, repetitive visually and partially non-distinguishable from one another or their function.
Example: if you want to depict the Layer tool, why don't you give it the icon of a partially cut onion that depicts its layers? If you want to depict the Flatten tool, why don't you make it a Road Roller icon? For the Smooth tool you could depict a blurry sphere, etc etc. All these similar icons that are almost all based of some sphere make it hard to find quickly what you need.
