The reason the Hyrule Dagger, Scimitar, and the Red Mace are more is like Crest said, they are faster. Plus, they are more rare than the Hunter/Kiwi. I see like 15-30 people a day with a Hunter/Kiwi, but I only see 1-2 of the Hyrule Dagger, Scimitar, and the Red Mace. (Usually I only myself with it everyday.) But, not counting myself, I guess it would be 0-1 a day.
