Melee weapon with Reach of C. What gives?

In the corebook, in daggers and knives, are throwing knives, which have a reach of C.

Now, I understand that these are thrown weapons, but why do they have a reach of C rather than, say 1, and the Thrown quality?

Is this intended to mean that thy cannot be used in melee? That simply would make no sense, but if so, why not have them in the ranged weapons table?

No, it means that they can be thrown within Close range. Otherwise treat them as normal knives in regards to Reach in close combat.

Thank you for the clarification.
