The first real, working lightsabre has been created, using lighting components from simple home cinema projectors.

Star Wars fanatics will not be recreating their favourite film scenes with this device, however, as the portable laser is easily capable of inflicting fast and fatal injuries. The Spyder III Pro Arctic is the product of Hong Kong-based manufacturers, Wicked Laser, who say the laser is definitely not a toy.

"Extremely dangerous is an understatement to the power," a spokesman said. "It will blind permanently and instantly and set fire quickly to skin and other body parts – use with extreme caution and only when using the included eye protection."

The tool has 1 watt of power and emits a ray 1,000 times stronger than sun on skin. It can be seen by aircraft pilots from a distance of 45 miles and the manufacturers say it should never be pointed at vehicles, people or animals.

The UK is one of 70 countries where the laser – which some early reviewers described as 'about as dangerous as a handgun' – will be available. Upon purchase, customers must agree to a Class IV Laser Hazard acknowledgment to prevent misuse, but there are no mandatory age checks.

The Spyder III consists of adapted blue lasers from home cinema projectors and retails for approximately $200 (£135).
