Cutting? You can just about drop a laser in front of electrical tape and cut it haha.
Will cut a cd case nicely. Making a hole in about a second, you can slowly move the dot and cut it.
Anything dark and thin it will make short work of.
Imagine what you can do with a very strong magnifying glass on a super sunny day, just from much further away.
Scorch your name in a piece of wood from 5-10ft. Ignite materials in seconds. It's pretty amazing. I've accidentally lit many thing on fire testing the beams
That laser above I keep in my pocket daily. 2.6w is capable of everything I stated.
I smoke, and I rarely grab a lighter on my way out
