==Characteristics==
Blade Traps are formidable, mechanized obstacles equipped with spikes or blades. In most appearances, Blade Traps are impervious to all attacks, like with most obstacles. Some Blade Traps are dormant until approached while others move in a set path by themselves.

After being set off, a Blade Trap will slowly return to their original position.
Other Blade Traps, such as those in and , glide along a projected path. These Blade Traps move along the ground regardless of Link's presence, at a constant speed. The paths of these Traps vary; some move from one side to the next, while others move in a complete circle.
