Changing your Fingerprints
You can cut your finger a thousand times, but the finger prints will "grow" back the same almost every time. Sorry, it's hard to change, unless you change your genetic makeup.
You can, however, place a scar over the ridges. To do that, you'd have to damage the dermis layer of skin. That one goes way deep, to cut it off would pretty much slice your finger in half. And even if you cut it pretty deeply, the covering scars will still grow back as tiny little dots.
Dots. That's all they are. I've seen a few pictures of people who tried to change their prints. Learned enough interesting things for a lifetime in one semester of Forensics Investigation. But yeah, before scarring, just normal prints. After, you get these little dots anyone with 2 eyes and a brain can match the scarred to the unscarred print.
ONE MORE THING.....
When you scar your prints, it makes you stand out like a neon sign. In the US, there are countless hundreds of thousands of people with the sworls and ridges similar to yours. But people with the scars, that's something rare. The scars mark you, forever, and you'll stick out like a 1985 Beetle with shiny new spinning rims. Eww.
