Bumping this thread to the top.
Knives are not back on HKG-YYZ (CX 828) on November 14th, still plastic in J. Flight was wonderful, no complaints with fantastic service on a 15+ hour non-stop! I'm very happy!
The plastic knives issue can be traced as a security issue with the Canadian GTAA whom needs a serious reshuffle and complete management change. They suck!
