Techno Blades

The Techno Blades are weapons seen in the third season of LEGO Ninjago: Masters of Spinjitzu. The Ninja obtained them at Borg Tower when they first met Cyrus Borg, along with their Techno suits. They can "hack into systems" and transform ordinary machinery into vehicles.

Functionality
When dormant, the Techno Blades lack their distinctive heads and much of their power, being too dull to effectively cut most objects. However, their true power is revealed when in the proximity of a hackable machine; the Blades grow in size, and their blades become sharper and begin glowing. It is then that the Techno Blades truly work as weapons and hacking devices.

Appearances
The Techno Blades first appeared in "The Surge," concealed in a statue that Cyrus Borg gave to the Ninja when they visited Borg Tower. When the statue was broken, the Ninja were able to grab the Techno Blades, don their new suits, and use them to escape a mysterious enemy controlling the tower's security system against them.
