lopping hairs only tells me the edge is sharp
the shave test is the only test to tell if it is SMOOTH

I have had many a blade lop hair no problem, but felt like shaving with a hacksaw blade,

this taught me:
1. sharp does not always equal smooth or comfortable shaves
2. to lighten up on the hone pressure once the bevel was set & definitely for the final grits,
3. some blades are just angry (a couple of Germans I have found) and need extra attention with feather weight then extra stropping to smooth their edge.
4. all get even better after several uses

This is JMHO & YMMV
