4 sided pasted paddle strop vs. a wet stone (Norton 4/8, etc.)

Maybe I just don't understand what they are for, but would you use one over the other, or the paddle for the fine polishing and the wet stone to restore the edge?

I understand honing a blade as I use a honing steel against my chef's knife (what I would guess just regular leather stropping is equivalent to) and machine grind the blade when it gets too dull, but I am confused about these two.


Thanks in advance!
