Traditionally, all saws for wood had either rip or crosscut teeth. In the last few years, however, manufacturers have been able to produce teeth that can cut in any direction both across and along the grain.
These teeth are now pretty much standard on most hand saws, however, you will find that the design varies between brands, and each manufacturer refers to them using different terminology.
As a result, rather than seeing a saw with crosscut or rip teeth you are more likely to come across universal, general purpose or even hybrid teeth, depending on how that particular company has branded them (but, in fact – they all do the same thing!)
