The traditional wooden ruler had the pervertible properties of the dual-purpose nature so as not to stick out to the [[class]] as only there to [[chastise]] and the durability that you didn't need be partially careful about it break when used as a spanking implement, however as in its primary design usage the wooden measuring edge was prone to denting making flaws for a drawing guide as such have been phased out of typical [[classroom]] usage.
The denting flaw had a workaround of adding a metal edge to the wood. As a spanking implement, this was less useful as a less than perfect [[stroke]] could land slightly turned and his mostly edge-on on the metal side possible causing undesirable [[welts]], [[bruseBruise|brusing]] or cuts. And from a primary usage point of view, the additional expense made less the ideal, and the design made the wood/metal join not particularly long-lasting; whereas the full metal ruler didn't have this durability flaw and not only shared draws of both expense and pervertible dangers, but metal temperature expansion issue make less consistent a measuring implement.
The plastic ruler by contrast has all the advantages of cheap, doesn't easily dent, and not only doesn't have the temperature altering it measuring, but their ability to be [[transparent]] actual also makes them the superior choice for accurate measuring. This means they rapidly replaced the traditional wooden one in classrooms once they became cheaply available. However, as a spanking implement, they are prone to snapping. In theory, stronger plastics like [[lexan]] could be used but they're not as cheap and schools that still use [[school corporeal punishments]] are more likely to use a dedicated spanking implement than relay on an obsequious pervertable.
