Yes, and no. Y'see, the class four laser isn't the OMGWTFBBQ laser. It's anything above a class three laser, which means it can potentially burn or harm. However, the military grade lasers they're currently playing around with, are inordinately more powerful than this particular match lighter. Allow me to clarify.razer17 said:A strong perfume can't permanently blind someone with a split second contact. And no, a bright torch is no where near as powerful as a class 4 laser. There's a reason that these things are used by the military and industry. They can cause immediate and permanent eye damage.
This particular lightsaber uses a 1 watt beam.
They have only admitted the capacity for weapon's grade lasers when they managed to develop a 100 kilowatt beam.
So, the proof of weapons grade laser had to be 100,000 times as powerful as this particular devise before people would start taking it seriously. Yet, it's still a class 4 laser. This thing is not as powerful as you think it is, it at most is likely to singe you, it's 'cancer' causing properties is likely only a little higher than getting sunburn, and there are handheld torches bright enough to blind you, and get this, in both eyes at once.
Theoretically dangerous? Yes. Practically dangerous? Possibly. Dangerous enough to warrant fear mongering, screaming in the streets and justification for the nanny state? Not a chance.
