I was wondering how shaving is carried out in the world of HP.
I remember someone getting a razor (from Bill and Fleur?) but can't remember the book. However, a razor is a very broad term. As the magical world seems to shun the muggle world; candles and lanterns rather than electric lights and torches for example, do the wizards use a straight edge blade, or a DE safety razor?
I do recall something about using just a wand to cut someone's hair (by Mrs Weasly?), is there any record/note/head-canon of shaving carried out via a cartridge razor, or anything of the like?
I would have thought it would be included in some format at the school, after all they're all of the age where they'll have to start shaving (or getting a beard).
This is not about how Harry got his hair cut, or about hair cutting. It is about shaving and the tools that are used for that task. For hair cutting, it is suggested that a wand is an accurate enough tool, but shaving (which is a more precise task) may want a better, more refined tool.
