I will be travelling to CDG from YVR via YUL with my instruments. I know I can't take my reed making knives and razer blades with me, and I am actually packing most of my reed making kit in my checked bags, but I want to bring my shaper tips with me as I really don't want to risk them going missing (link to pic below).

The longest one is 2.5 inches long and the shorter one is 2 inches long. Does anyone think that I run a risk of having them confiscated?
