Machete's, hangers, and sidearms are frequently discussed under knives. These are primarilly tools, like large camp knives and khukuries.
Swords, on the other hand, are obsolete weapons.
Real historical swords are scarce and expensive, and generally purchase by collectors who are more interested in preserving them as historical relics, rather then fencing with them. The discussion around these things center on history, ethnographics, markings and such, and can be very esoteric.
That leaves the reproduction swords used by martial artist, or re-enactors; the ultra-expensive art fantasy pieces, and the mass quantity of cheap and dangerous sword-like wall decorations. Once again, a very divergent set of interests which are hard to approach in a general forum like this, without a great deal of frustration.
