I am with Chester on this one; forcing steel at low temperature into a different shape stresses the metal by forcing the crystals a (tiny) bit out of their natural position which stiffens the steel in every direction, though maybe not equal in all directions.
@ Seraphim; by how you glued your shark on the chopsticks you took out most of the blades flexibility. Only twice the width bevel is allowed to flex here. When you would have turned your chopsticks by 90 degrees and glued your blade on the thinner part would make a lot of difference and be much closer to how it is held in a razor I think. Interesting topic btw, I love these kind of debates!!
I must to the barber's, monsieur, for methinks I am marvellous hairy about the face
