If I were you I would take the Wipienica that is shaving but pulling and do a 3-3, 1-3, 1-5 on the Norton with light even pressure. Then wet the yellow coticule and do 10 to 20 passes on that. Finally do 10-20 passes on the chromium oxide. Strop the razor and test shave. Let us know how the test shave goes and we can advise you further if the razor is still not there.
