Broken mouthpiece

I was tightening the ligature (circular piece that holds the reed onto the mouthpiece) to start my eagerly-awaited Book 2 practice session; venturing into semi-quavers; when my unfortunate fingers slipped and dropped the mouthpiece onto the floor. It made a small chip on the corner edge, enough to decommission my piece into the bin.

Checked with my tutor whether it was necessary to try another brand/type, but he recommended to maintain use of a Yamaha alto saxophone 4C. It'll cost me RM100 to replace.

Here are the 'casualty' photos;
