Lots of potential weak links I think.

One, the hone must be lapped

Two, the touch on the hone must work up to the weight of the blade and a very smooooooth edge on high grit

Three, the razor must be stropped very lightly without downward pressure into the strop.

You must make a mental image of a razor's edge on the end of your straight. It must be treated delicately.

You must know how to assess whether the edge is shavable before you start.

You must prep your beard very well.

You must support the face against the movement of the razor and stretch the skin.

You must use the correct angle, not tearing the edge up nor tearing at your face.

You must let your face dry completely before sitting there like a dork (we've all done it) and checking just how close it is. Its just a shave after all.
