These two are like cousins.  The handles are exactly alike and you don't know which one is which until you open them.  The blades are both VG-10 steel, which is very sharp and holds an edge fairly well.  They make a nice set and are both superb knives.  The Pentagon Elite is serrated and has a dagger like appearance.  Open easily and looks fierce.  I prefer the 4 inch blades since the 5 inch are illegal to carry in most areas.
