CHEMISTRY LIFE HACKS
HOW TO SHARPEN YOUR KNIFE WITHOUT A SHARPENER
You’ve got yourself a pile of
tomatoes to cut up but that knife
of yours just isn’t cutting it today.
You open the drawer, can’t
find your knife sharpener,
so now what are you going to do?
This hack has you looking no
further than your dishware.
Take a porcelain plate and put
it upside down on the counter.
Notice how there is a circle of
rough porcelain that hasn’t been
glazed over where the plate usually touches
the surface of your table.
Take your dull blade and slide it in
one direction at a 20° angle against this
rough edge of porcelain.
Keep repeating on both sides
of the blade several times.
Rinse your knife afterwards,
and get back to cutting.
A stainless steel knife is sharp
because of the way that the blade
tapers down into a tight point.
Now that tight point isn’t perfect,
and there are little tiny fragments
of steel that push outward, and
act sort of like teeth on a saw.
This is why pushing a knife straight
down into food doesn’t cut as well
as using a pulling or pushing motion
The bottoms of a ceramic plate,
bowl, or even coffee cup are
actually hard enough offer a good temporary
solution to both true
your blade’s edge, that is, make
it as straight as possible,
and also remove some surface
steel to create a refreshed edge.
Best of all you can then use
the plate for your food.
Oh yeah.
