In YouTube videos on using the straight,
What's your experience and observations concerning slicing motion with a straight?
- some advice to move the razor only perpendicular to the edge (the way the double edge moves as it is pulled by a handle that is at 90 degrees to the blade), never moving it parallel to the edge (the way a knife moves as it slices bread); but
- but others advice to move the straight a tiny bit parallel to its edge (slicing) as it is moved mostly perpendicular to its edge.
