How to Sharpen Scissors

Don't just throw away dull scissors without giving them a second chance.  With a little elbow grease, you can sharpen scissors to good as new.  It's easy to learn how to sharpen scissors.

Maybe they're not dull

Scissors of all kinds gradually wear out over time.  When they start to dull, it's not always due to the blade.  Sometimes giving scissors a quick wipe will remove a lot of gunk and rejuvenate sharpness.  If that doesn't work, then it's time to bring in the whetstone.

A trip to the hardware store

Every shear from home to barber scissors can benefit from a quick sharpening.  The first step is to get an aluminum oxide bench stone.  Brown with a porous texture, they sharpen scissors quite well.  Here are some following points for caring for the stone:

A good first soaking:  New whetstones should be soaked overnight in a pan of machine oil.  These stones are porous, and a good initial soak will keep the pores from getting clogged.

Periodic oiling:  The whetstone must be oiled lightly before you sharpen scissors.  This lubrication process will prevent unnecessary scratching and extend the life of your blades.

Storage:  Keep stones in closed box to prevent clogging from dust.  Bring out only to sharpen scissors.

Note that to sharpen scissors, these whetstones need machine oil.  DO NOT use vegetable oil as it will clog up the porous properties used to sharpen scissors.

The process

Keep in mind the goal is not to make the make the scissor blades ridiculously sharp.  Scissors actually cut by ripping through fibers, not slicing them (much like serrated edges).  Sharpen scissors according to the following simple guidelines:

Use the coarse side of the stone to sharpen scissors.

Sharpen scissors along the beveled (angled) edge of the blade.

Align the blade angle against the stone.

Starting from the point, slide the blade forward along the stone to the pivot point.

Repeat this process on both blades to sharpen scissors.

Sharpen scissors then test, opening and closing to make ensure smooth action.

If the pivot joint is loose, screw or hammer back into tight placement.

Sharpen scissors at least twice a year or as needed.

When you sharpen scissors, be sure to exercise caution and common sense.  The blades are opened wide, and getting a good grip means holding on to the opposing blade.  In a few minutes, the blades are refurbished and ready for use.
