How To Sharpen Swords
– A Beginners Guide
What follows are some basic techniques you can use to sharpen swords.
While in this day and age, a sword doesn’t have to be sharp to be classed as “battle ready” or functional, personally I prefer my swords to be sharp.
And if you prefer yours to be sharp too, the following guide will help you transform a blunt sword into a sharp one WITHOUT ruining the geometry or the temper – or losing any fingers in the process...
--------------------------------------------------------------------------------
The Basic "Do's and Don'ts" of Sword Sharpening...
DON’T attempt to sharpen swords that are antiques – leave that to the experts, otherwise you will almost certainly destroy their value.
DON’T use power-tools to sharpen swords. The friction heats up the blade, ruining the swords temper and heat treatment, and it's all too easy to lose the swords geometry. If you must use power tools (for example, to reshape badly chipped blade) use a Makita wet grinder, the grinding wheels move slowly and the water keeps the blade from overheating.
DO be very careful and patient when sharpening swords. More accidents occur when performing sword maintenance than at any other time, so make sure that you are paying 100% attention to what you are doing and eliminate outside distractions.
DO get some practice on a cheap stainless steel wall hanger before attempting to sharpen a more valuable sword. You will probably destroy the geometry of the first few blades you try and sharpen – so it's better to get your practice in with something less than valuable.

What You Will Need to Sharpen Your Sword With
At a bare minimum, you will need:
1) A sword…
2) A metal file
3) A whetstone
4) Oil for the whetstone
5) 3M 400 Grit Emery paper
6) Some paper (to wipe stuff with)
7) And a block of wood
8) Some patience
9) And some elbow grease...
Now if you are only retouching an edge on an already sharp sword, you can skip stage 1 altogether and proceed to either stage 2 or 3 depending on how sharp your sword already is.
POWER TIP
When you sharpen swords ALLOW THE EDGE TO REVEAL ITSELF.
The most common mistake when you sharpen swords is paying too much attention to the edge. Instead you should concentrate on simply removing the metal until the edge is naturally exposed.
REMEMBER: there IS such a thing as a sword that is TOO sharp! If the sword is too sharp, it will very rapidly lose its edge when cutting and may even chip and break. So when you sharpen swords, less is more.
STAGE ONE
>
Set yourself up somewhere where you are comfortable and have plenty of light, lay your sword on the table and prop it up with a block of wood or something similar.
Using even, measured strokes at a 30 degree angle, proceed to roughly begin shaping the edge with your file.
Pay attention that you don’t take too much of one side – just keep turning the blade over until a rough edge starts to appear. It will look very rough at this point, but don’t let that worry you – you will refine the swords appearance in the next two stages.
STAGE TWO
Now get out your trusty whetstone and apply a thin film of oil to the surface.
What you are doing here is polishing, not grinding – so pass the blade over the stone, again at a 30 degree angle, using a slow and uniform stroke.
The motion you should be using is just back and forth - NOT polishing in a circular fashion.
Make sure that you inspect the blade often, and don’t worry about how the blade feels yet.
Just make sure you have worked the stone over the entire surface of the blade while maintaining the surface geometry.
A good light source is essential to seeing where you have missed. Remember that you are not sharpening the edge. You are removing metal until the edge is exposed.
STAGE THREE
To complete the sword sharpening process, and blend your newly sharpened blade with the rest of your sword, get some 400 grit sandpaper from 3M (don’t bother with the cheap stuff – its not worth it!) and tear off a postage stamp sized piece (see left).
Wet with a little water, and VERY CAREFULLY run the paper along one side of the edge of the blade with your finger at a 30 degree angle.
I can’t stress enough how dangerous this can be to your fingers and just one slip could open up a very nasty cut. So make sure you turn off the TV and focus ALL your attention solely on what you are doing when you sharpen swords or YOU WILL CUT YOURSELF!(Besides, focusing intently on this process is actually quite therapeutic and relaxing - in a slightly disturbing kind of way...!)
Finally, you might optionally want to consider rubbing the blade with some water and vinegar to brown the surface of the blade to make the sharpening less obvious still.
Looking for a shortcut?
Of course, if this all sounds like too much trouble and/or you are in a hurry you can also use a knife sharpening tool to sharpen swords with. The best one I have found that actually works for swords (many do NOT) is the Accusharp, a $13 tool with dual carbide blades that creates a quite servicable edge that anyone can do.
The drawback is that an experienced personal using the more detailed method shown above will get a better looking and more satisfying edge.
