Fire Swords

The Fire Swords were wielded by Princess Snakes servants. They were long, flat, and wide. These swords did not contain much decoration except for a little sash dangling off the hilt of each one of them. We never actually get to see anyone fight with these swords, so it is assumed that they were mostly for show just like everything else Princess Snake did.

Hand Blaster

Throughout the universe, the art of wielding ki was fairly rare in terms of mediocre species. Because of this, Furiza's Scientists invented a small device that fit onto the hand and could wield a person's ki for them. This Hand Blaster was quite weak in terms of power, but since Furiza's lower-level henchman were bullies that didn't attack strong opponents, they didn't need powerful blasts. It is assumed that the amount of ki put into each blast was determined by the user's power level. Not all of Furiza's henchmen carried one of these, but all of King Cold's lower-levels sported them.

Chi-Chi Helmet

In the early days of Dragonball, young princess Chi-Chi wore a Helmet that allowed her to shoot a laser beam at enemies when she was frightened. The beam was actually quite powerful and easily killed a dinosaur. The helmet was most likely made by her father, the Ox-King, who also sported similar clothing as her. During the time period between two budoukai's when Chi-Chi grew up, she gave up wearing the helmet and relied on fighting skills alone.

Janemba Sword

Janemba's Sword is seen in movie 12 and is used only by his second form. The sword is a deep red color, with a silver hilt and is by far the coolest looking sword in dbz. He uses the sword against Goku, and although he was an excellent swordsmen, Goku eventually killed him anyway.

Minosha Sword

Tapion's brother, Minosha, had a Legendary Sword that was seemingly identical to his brother's except that the hilt decorations faced downward instead of up. He used this sword to fight Hirudegarn, and even though he was a great sword master he could not defeat this ancient monster. He was destroyed, and his sword perished with him.

Tapion Sword

The warrior Tapion wielded a Legendary Blade that was identical to Minosha's except for the decorations. During movie 13, Tapion does not fight much, but at the end of the movie he gives his sword to Trunks. This was an attempt by TOEi to explain how Trunks got his sword, but it leaves a lot of plot holes. How trunks came upon this sword in the real timeline is unknown. After a while of using it, Trunks becomes very precise in his movements, and with the sword combined with his Super Saiya-jin power, he became a very formidable foe. It was with this sword that he defeated the Tyrant Furiza and King Cold.

Zed Sword

The Legendary Zed Sword was introduced to us during the Buu Saga. It is a holy sword that was stuck in the ground by an 'incredibly strong evil fellow' (according to Rou Dai Kaioshin) after the evil fellow trapped Rou in the sword. It had been stuck in the rocks for fifteen generations of Kaioshins, who all tried to pull the sword out. It was said that whoever succeeded in pulling the sword out would receive incredible power, enough power to defeat even Buu. However, the receiving of the power was far different than anyone could have guessed.

Mutchy-Motchy Whip

Mutchy-Motchy, high priest of Lude, had sent out the Bonpara brothers to find the Dragonball's. If they didn't succeed, he used a Whip to turn his minion's that didn't find Dragonball's into small dolls. After turning them into dolls, he would throw them into a giant furnace that caused Ruudo's statue's eyes to glow.

Gohan's Sword

After the battle with the Saiya-jin, Piccolo saw Gohan's potential and decided to train him on his own. The first thing he did was leave Goku in the wilderness alone, and he created a Small Sword for Gohan to use as protection and as a tool to find something to eat. Gohan used this sword a lot on his adventures in the wilderness and became quite good at wielding it. However, after he finally makes it home we never see him use this sword again.

Bulma's Gun

During their first encounter, Bulma was scared that Goku was going to hurt her so she shot him with her Gun. The bullets hit Goku dead on, knocking him back, but he got up and wiped himself off. This surprised Bulma so much that she wanted to know more about Goku and thus the saga began. 

Katana

Yajirobi carried around a very sharp Katana that he was a master at using. It is said that he was the greatest swordsmen on the planet Earth. Because of his lazyness though, Yajirobi never becomes very powerful. However, he does play a large role in the Saiya-jin Saga by chopping off Oozaru Vegeta's tail, causing him to revert back to his original form.
