All the cuts on a bump key are made to the maximum depth, so any key blank can be made into a bump key. Bump keys are manufacturer-specific.

When Linnaeus developed his system of classification, there were only two kingdoms, Plants and Animals. But the use of the microscope led to the discovery of new organisms and the identification of differences in cells.A two-kingdom system was no longer useful.Today the system of classification includes six kingdoms.hen Linnaeus developed his system of classification, there were only two kingdoms, Plants and Animals.
