Jay's blade has a yellow blade and a chainsaw blade as a hilt. Zane's is a staff with a blue "blade", and Cole's looks like a nunchuck with a green "blade".
History in Canon
The Techno-Blades were made by Cyrus Borg, who hid them in a statue and gave them to the ninja to protect. They can destroy the Overlord in virus form by rebooting the computer system that he is in, but unbeknowest to also release him out of the digiverse, which is the reason why Pythor wants them.
When ninjas entered the digiverse, they used the blades to recreate their vehicles in the computer system and to hack the mainframe. The blades were destroyed when the Ninja used them to reboot the computer system. Ultimately, the blades didn't cause a difference, as it turned out that the Overlord escaped the system before he could be destroyed.
- The Techno-blades are not really blades. Better names for them would be The Techno-Blade (Kai), the Techno-Chainsaw (Jay), the Techno-Staff (Zane), and the Techno-Nunchuck (Cole).
