I think he acted fairly and can't see the problem with asking you about the knife. As has been said he didn't do you for it, which may have been overboard, he questioned you and advised you to put it out of sight, no problem there!
I think we should be stopped and questioned more, not less, it is the best way to detect and prevent "real" crime and as I am (generally)law abiding I would feel safer,for myself and my family, if spot checks were carried out more often. I usually carry my opinel in my pocket and my "tools",bushcraft and outdoor kit including my mora, are usually left in my car. I know the laws but I pretty much trust the system in the very unlikely event of a pull, but if I thought I was going to be stopped I would leave my sharps at home (or carry a 100% legal slipjoint) just to save on hassle, anyone up to no good would think the same I would imagine.
As for hiding with a speed gun.......
At least you were stopped, not just policed by camera and post!
