Blue laser pointer is actually an ideal tool for burning stuffs, with adjusted the laser beam focus. The strong powered laser can set fire on matches, paper or other imflammable objects just like a lighter can do but with the burning laser, you'll be able to light the stuffs at certain distance without getting closed.

With countless reports critized on the high power laser pointer hazard to human bodys. I would insist that anything that can burn up a fire is dangerous at the same degree, a normal lighter or knife also do harm to humans but that don't mean people should not use these tools. Great power tools brings greater danger, proper operation is the most important thing before you use a burning tool.

In fact, class 3 or 4 laser pointers only be dangerous when the shining laser lights shoot or reflect towards human body, especially the eyes. The higher power, the exposure time to cause damage will be shorter. Avoiding laser beam just like avoiding the fire burns you, that's enough to keep you safe, a professional laser goggle will be a plus to keep your eyes safe if you need to stare at the shining laser for a long time.

Class 4 laser pointers are the ideal choices to used as a burning tool. Compared with green or red laser pointers, blue laser beam is dim but more powerful to able get stuffs burned.
