I've yet to finda razor that some variant of the X-stroke can not hone. I do however, have several that can NOT be honed with straight back and forth strokes on a 3" wide hone. Not unless you want to turn your smiling razor into a frowning razor.

Same thing applies for strops and the X stroke. I don't have a single razor that can not be stropped with an X stroke. I do have a few that, if using straight back and forth laps you will never touch the heel or toe with the strop.

YMMV.
