Hand, Yes, degrees/side, is the way I give it . Yes, technique has a lot to do with it and a guide helps . I think your thoughts are correct . I only strop once between sharpening on a stone . As the stone edge is better and I'm not talking much stone work here . Stropping alone could put off going to the stone one additional time but I'm like you, it rounds the bevel . I've talked with barbers and they tell me they will always stone and strop their razor between shaves . Because 1) it needs some and 2) they can't afford a dissatisfied customer . So, barber's don't care about testing for edge retention . Its 'the close shave' they're after . I've noticed this with mine as well . I could get one more shave off the blade but it wouldn't be as close as that first one . Also, beard preparation helps, that hot towel works wonders on whiskers . DM
