So I've been working on sharpening up a smiling w&b quarter hollow (marked "The Celebrated - Hollow Ground". I've been doing a rolling, sweeping x stroke, but the bevel is not establishing itself on the toe and heel. The centre of the blade will pass the hht off of my japanese 1k, but the toe and heel are lagging behind to the point where the bevel is twice as wide at the centre. on the tnt, 3/8 of an inch at either end lacks the bite that the middle shows. does anybody have any tips for re-establishing an even bevel on a smiling blade?
