Porcelain Tile with sharp edges
I installed a tile like that several years ago, what a pain, had to wear gloves because of the sharpness.
What you have is a poorly finished rectified tile. It was made the normal way, then it was put through a rectifier which grinds the tiles to make them square, hence no eased edges. Tiles are rectified so they can be set closer and reduce the amount of "grout valley". It's a nicer look and easier to maintain.......however rectified tiles are harder to work with.
You need a very flat floor and take your time setting them. Normally the spec is for the floor to be flat within 1/4" in 10 ft. and 1/16" in 12" of the required plane. With large tiles you want it flatter than that, I say within 1/8" in 10 ft. max. Maybe keep looking if your floor isn't that flat.
