I was browsing through this ebay seller offerings (http://stores.ebay.com/Two-Finger-Knife-LLC?_rdc=1) and it seems every particular shape has a name.
Is there a catalog with the different standard names?
Not sure about a catalog Pablo, but I was also curious and did a web search for blade shapes and found this. There are so many different shapes and you will probably find that some knife shapes can be a combination of different shapes. Mostly depends on the knife makers individual interpretation of a given shape for a given use of the knife. For example a drop point knife used for skinning may look different depending on who made the knife design.
