How to Sharpen Your Screwdriver Blades


If the tips of your screwdrivers are too wide
to fit in the small spaces you need to use them, like in those tiny watch screws, or
if they’ve simply become worn or dull over time Esslinger-dot-com has the information
you need to sharpen your screwdriver blades and get them working once again. How can you tell if you need to sharpen your
blades? Look at the tips. Over time, your blades can be chipped or have sections sheared
off and lose their straight edge. To fix it, you would simply grind off the uneven end,
however that makes your blades too wide to fit in most small screw heads and that is
when you need to sharpen the blade. Be aware that you can only sharpen flat-head screwdriver
blades. Things you’ll need:
A Loupe or other magnifier A screwdriver holder
A sharpening stone And a Selvyt or cleaning cloth First you will want to examine the tips of
your screwdrivers to see which will need to be sharpened. Position your loupe so you can
see the magnified tips. If the blade tapers to a blunt end instead of a fine tip, you
will want to sharpen it. Once you know which screwdriver blades need
to be sharpened. Select one to start sharpening and set the rest aside where you can reach
them later. Take your screwdriver holder and squeeze the
ends together to reveal the hole for your screwdriver. Hold the ends together and slide
your first screwdriver into the holder. Position the screwdriver in the holder so
that the solid portion of the screwdriver handle above the blade is sitting just inside
the holder like this. After you have the screwdriver positioned
in the holder, you will want to align the screwdriver blade with the holder so that
you can sharpen it evenly. The blade should be parallel or flat with the tool, like so. Since there is nothing to obviously orient
the blade to, you will have to eyeball the correct position as best you can. We would
recommend that you use your magnifier to check the alignment when you think you have it in
the correct place. When you are satisfied with the position of
the blade, take your screwdriver and holder and place it over the sharpening stone so
that the blade is on top of the stone itself and close to one end of the stone. Now you are ready to begin sharpening. Use
your index finger to push the blade of the screwdriver down against the sharpening stone
as you grip the holder. Be sure to use medium pressure as you press
down on the blade. You want enough to keep the blade against the stone and sharpen it,
but not so much that you are grinding the blade into the stone and risking breaking
it. Once you are comfortable with the position
of the screwdriver you are going to slide the blade back and forth across the long side
of the stone to sharpen it. Keep the pressure on the blade steady throughout this process. Count each back and forth motion as one pass
across the sharpener and start by making ten passes across the stone with the first side
of the blade. Check your progress. You should be able to
see where you have been grinding away at the blade. Then, turn the screwdriver and holder over
so that you can repeat this process on the other side of the blade to sharpen it to an
even point. Hold the blade to the surface of the sharpening
stone with the same amount of medium pressure that you used before, and make ten back and
forth passes with the blade across the stone. Check your progress again. You should be able
to see where you’ve ground away a small bit of the blade on either side. Wipe the
tip of the blade with your cleaning cloth to clear away any debris. Examine the blade from the side so that you
can see how fine the point is. If the blade is still mostly blunt, repeat
the process and grind a little more from each side of the blade edge. However, be careful not to over sharpen the
blade. The sharper you make it, the weaker it becomes, so you must aim to find the balance
between a fine point and weak point. Once are satisfied with the sharpness of the
blade, you will want to examine the tip again. It should be the smallest bit squared off
at the end to allow it to grip in a screw head. If the blade is knife-point thin, take your
sharpening block and hold it upright so that you square off the end of the blade slightly. Hold the blade tip perpendicularly against
the sharpening stone and make a small number, usually about five, of back and forth passes
to correct the edge of the blade. Be sure to check your progress often so as not to
over flatten the tip. When the tip is slightly squared, and the
blade is the right thickness, wipe off any remaining debris and you are finished. Repeat
these steps to sharpen any of your other screwdrivers that are getting a bit dull. For other great watch repair tips and tricks,

  1. When I need to use a tool like this to sharpen a flat blade driver is the day I turn in my tools. I was looking for how to sharpen Phillips drivers but, oh, never mind.

  2. I noticed no honing oil was used. I have a similar (Horotec) sharpener. India stone absorbs oil like a sponge. Not sure I want to soak it however.
