I would also like to add to that list a little bit of information about some of these weapons.

Traditionally, most of these weapons were considered lesser weapons when compared to the much more important daisho: The combination of katana and wakizashi which marked the station of the samurai. Even non-bushi samurai (for not all of that class were warriors) would wear the swords, as a mark of station.

The other weapons were not considered dishonorable to carry, but they were viewed as lesser weapons. Most of them were tools which could be used as improvised weapons, since the hinin (peasant class) were forbidden to carry the daisho, and in most cases, any weaponry at all. But, if you were fighting indoors, you were often not allowed to bring your sword inside with you, so having a jitte on your side would be a tremendous advantage versus an unarmed opponent. In fact, it would also be an advantage versus an opponent who was foolish enough to bring a sword into that cramped area: You could easily enter his range and disarm him, and then you would be the only armed combatant.

So, for this reason, many samurai would later carry these unorthodox weapons. They would also train with less deadly weapons, such as the bokken. As time progressed and the importance of the samurai lessened, the hinin weapons became more important. Primarily because many of those peasants who became masters of these unorthodox weapons had become the new police. (There's some indication that those were were "asked" to provide the lord with services he could not ask for, those which were beneath the station of the samurai -- the ninja-- were later to have become the police force. It might be true.)
