Blade Trap
The Blade Trap is an inanimate enemy first introduced in The Legend of Zelda. It has appeared in every game to date with the exception of The Adventure of Link.
The Legend of Zelda
These traps appear in the corners of some rooms in dungeons. When Link crosses their path, they fly towards him until they hit each other or another obstacle, then retract to their original position. They cannot be defeated because they're essentially an obstacle.

Link's Awakening
Blade Traps can be found in dungeons around Koholint Island. They have the same function as they did in The Legend of Zelda, and can be jumped over with Roc's Feather.
Ocarina of Time
These spiked obstacles are invulnerable and come in two varieties: ones that move in a set path and ones that ambush you if you get close. Either way, they cannot be defeated, so just wait for them to get on the far side of you and sneak past. In some puzzles, you can use blocks or statues to put in their path so they don't have much wiggle room. They appear in Dodongo's Cavern, the Ice Cavern, the Water Temple, the Shadow Temple, the Spirit Temple, and Ganon's Castle.

Oracle of Seasons
There are 4 different types of Blade Traps featured within Oracle of Seasons.
Blue Trap
These work the same like the traps from The Legend of Zelda and Link's Awakening.
Green Trap
Unlike most of the other traps, this one doesn't slow down and retract. It continuously goes back and forth, making it a bit more difficult to pass, similar to the ones from Ocarina of Time except faster.
Orange Trap
This is the fastest trap in the game, similar to the blue trap except when it's activated, it goes much faster, but retracts more slowly.
Giant Traps
These traps are much larger than normal traps and follow set paths. They come in red and orange colors.
Oracle of Ages
There are 2 traps seen in Oracle of Ages, blue and green. They act exactly similarly to the blue and green traps from Oracle of Seasons.
Four Swords
The blade traps in Four Swords are very similar to other appearences. They only dash out at you when you coss their path, the kind that follows a set path is not present. Another enemy, similar to blade traps, can retract it's blades when in rest. The latter enemy comes in two kinds: those that dash out at you when you cross their path, and those that chase you until you lose it, e.g. by placing a bush between you and the blade. All the varieties are found throughout most of the stages, however Hero's Trial (in the anniversary edition) makes abundant use of them.
The Wind Waker
Blade Traps appear in the Wind Temple. They are invulnerable and move back and forth. In order to make it past the room to get to the boss door with Makar, blocks must be placed strategically so that they block the Blade Traps so that they don't get in your way.

Twilight Princess
Blade Traps appear in the Temple of Time. They are very similar to their other appearances because they are basically a moving obstacle. However, this is the first and only time that they are destructible. By taking control of the huge statue and its hammer, one swing obliterates a Blade Trap.

Skyward Sword
The Blade Traps featured in Skyward Sword can only be encountered when a Timeshift Stone is activated. These enemies can be found specifically in Lanayru Gorge when delivering a Timeshift Stone to Lanayru to learn the Song of the Hero.
