Clow Cards | Clow Cards were created by the ancestor of Syaoran and Meilin, Clow Reed. There are a total of 52 clow cards, and a mysterious 53rd clow card, i think it's the hope card. The cards are entitled with something like, "The Firey" , thus the name the firey, that card has the power of fire. These cards are usually forms of young girls, or women, not all cards, like the create, the flow, and the fly, are in forms of a lady though.

Clow Book | The clow book was created by Clow Reed. Knowing that the cards that he created were to powerful and had powerful magic embedded in them, Clow Reed created the Clow Book to put all 52 clow cards in to protect the world from their harmful doings. But if someone containing magic in them, opened "The Clow" and read the scripture, then all of the clow cards would be set free.

Sealing Wand | The sealing wand is what Sakura wears around her neck. When shruken, the Sealing wand is called the "Key of Clow", which is like a necklace which Sakura wears. When Sakura says a chant, the Key of Clow enlarges into the Sealing wand. Which Sakura uses to capture clow cards, and summon them for use. The sealing wand is a bird like baton, with wings so Sakura can fly by summoning the fly card.

Sword | Syaoran also has an item which he uses to summon the clow cards that have flown to him. For when Sakura seals a card, the card flys to the person that has helped the most or something like that. Thus Syaoran can only summon but not capture/seal clow cards with his sword.

Lasin Board | The Lasin Board is another item that Syaoran uses. When Syaoran says a chant, the lasin board points to what Syaoran is looking for. The lasin board only can help Syaoran find such things as people, clow cards, or magical things.
