Bengaluru Metro Rail Corporation [bmrcl] — Scissors

Being a fashion designing student, I need to carry fabric cutting scissors for stitching. I travel all the way from whitefield to MG road metro. Initially the Metro security didn’t allow us to carry these scissors because they were huge ones. That is understandable but when I started carrying 20cm paper cutting scissors which is much smaller than the fabric cutting scissors they didn’t let me carry it again. Even after showing my college certificate they didn’t allow me. This is not acceptable. Most of the fashion designing students travelling by metro face this issue. Please look into this concern.
Thank you.
