The bottom of a ceramic plate or bowl can put a nice edge on a blade, so good one can shave the hairs off one's arm fairly easily.
In a survival situation I suppose the best place to look is in a riverbed for a hard flattish piece of rock.
To sharpen a blade you must think blade.
Push too hard and your edge will curl, too light and it'll take forever.
Pull away from the edge (opposite cutting direction) on the sharpening stone and you'll get debris and feathering on your edge, but sharpen in a
circle or into (cutting direction) the blade edge debris and feathering will slough off.
And your angle of attack must be right, smaller angle, sharper but more delicate edge, higher angle will make a less sharp, but more durable edge.
And when finished check the both sides of the blade feel equal with no edge chaff and feathering and if there is remove it by lightly honing it.
Note, I always lighten up toward the end of my sharpening because the sharp edge is more delicate and that is all that is needed to remove edge
That's mostly my method and I can shave my arms with a swiss army knife blade.
(Note: I do not normally shave my arms, or my legs.)
