Tile cracking at edge of cut

[Accountantbytrade]

I have a Rubi manual tile cutter which is quite new. It has been fine initially but now each tile I cut fragments at the top. I cut from the bottom up but three tiles in a row have cracked the corner off at the top. Any ideas what I am doing wrong? These are all standard straight cuts. Nothing fancy.

Cheers!

Ah right lol.
Try snapping the handle down quickly, this can shock into a better break.

What tiles were they ceramic or porcelain

I wondered that.

The score needs to be clean and perhaps try scoring from one side then spin the tile around and get it bang on, then score just the first inch of the side now near to you. Then snap quickly.
