30 passes isn't a lot of stropping to remove a burr. Saying that I have no experience of these particular knives so I have no idea what they're like. Perhaps now you've removed the burr you could try 50-100 passes on the strop and see if there's a difference? When you say pushing towards the edge do you mean whilst stropping?
I was pushing the edge of the blade into the stone, and dragging the edge whilst stropping. Since then I have given it a thick convexed edge, and relegated it to the display cabinet, but thanks for the advice.
