Cyrtomium falcatum. 1  Aptly named, Japanese holly fern produces fronds that do indeed resemble holly leaves with their glossy, deep green leathery appearance. 2  It needs moist but well-drained soil in a protected location to thrive. 3  It also makes for a good houseplant in climates where it isn't hardy.
A baseball bat is a third-class lever because the fulcrum is on the  end of one side, the effect force is in the middle, and the  resistant force, the load, is at the top.
The more negative the drop, the lighter the bat is relative to the length of the bat. So, in general, young kids will swing high drop (more negative) bats and older kids will swing low drop (less negative) bats. An important note about drop for older boys playing baseball: The natural drop of wood is -3.
