First step definitely would be to strop on leather much more. Try at least 50 strokes. Since it's been a while, be very careful to make each of those strokes perfect.

If still no go, then try repeating what you did once more, followed with the increased leather stropping again.

Only then would I suggest that you try the more aggressive pyramid.

Good luck and keep trying. Worst case scenario, send it out again for a touch-up. Odds are it needs very little to get it back up to snuff.
