Some recent grinding installations in Australia have demonstrated potential for ultra-fine grinding with acceptable power consumption (Johnson, 1998). A combination of high-pressure rolls and ultra-fine grinding devices could potentially save energy in the production of ultra-fine particles because they create micro-cracks during the crushing step.

Stone tools were made by taking a piece of stone and knocking off flakes, a process known as "knapping." When the flakes were used, the tools produced are referred to as "flake tools." When the core itself was used, it is referred to as a "core tool." (Naturally, smaller flakes could be removed from larger ones, so not all flakes came off of cores.
