To me, sharpening is an absolutely essential skill. It makes no more sense to me to own a knife and not make an effort to learn to sharpen, than to buy a gun and not buy ammo and learn to shoot.
It does take a bit of effort, and a little bit of investment, and some practice, but pretty much anyone can learn to do it if they want to.
I teach courses on how to do this, and have done so for many years. I have yet to encounter anyone from about the age of 9 and up who cannot learn to do this.
Here is a bit on how to sharpen a knife. Read this over a few times before you actually try to do it, and then be careful to follow instructions in detail. Hopefully this will all help!
When you sharpen, lay the knife on the stone at about a 10 degree angle.
Use a fair amount of pressure as you rub the blade on the stone and try to
maintain that angle as closely as you can. Keep working on that side of the
blade until you raise a burr on the other side of the edge. This burr, or
wire edge, must be evident for the entire length of the edge. Do not turn
the knife over until you have raised this burr. Do not quit too soon. If
you don't get this burr or wire edge, you will have no hope at all of
getting the knife really sharp. Once you have raised the wire edge, then
turn the knife over and do the same on the other side, until again you have
raised the wire edge the other way.
Now turn the knife to the first side again, and with fairly light pressure
give it 5 - 10 strokes, turn it over, give it 5 - 10, and repeat the
procedure until you do not detect wire edge on either side. It is essential
that you maintain the 10 degree angle throughout this entire procedure.
Now you need a strop, which is just any old piece of leather glued to a flat
stick and dressed with a good stropping compound. Again maintaining the 10
degree angle, and with QUITE A BIT OF PRESSURE, pull the blade (that is with
the edge trailing) along the strop. Be very careful to maintain the 10
degree angle throughout the entire stroke DO NOT ROLL THE KNIFE UP AT THE
END OF THE STROKE, and do not run off the end of the strop. Do not flip the
knife over at the end of each stroke and come back the other way on the
other side of the knife. If you do, you will be anticipating the flip and
almost certainly roll the knife up and as a result rub your edge off! Just
give it about 50 good strokes on one side and then do 50 on the other side,
and you should be able to shave with the knife, and more importantly, make
good feather sticks and whittle all kinds of neat stuff. When you lose the edge a
bit through normal whittlin', just give it a few strokes on the strop and
the edge will come right back. I usually strop my knife on about 30 - 50
occasions before going back to the stone. When you find that the edge only
lasts for a few minutes before you need to strop again, then it is time to
freshen up the edge on the stone. Remember to use fairly heavy pressure on
the strop. Don't use red jeweller's rouge. Use white or green,zam or
yellowstone or better yet - time for a commercial - Rick's White Lightnin'. It is not necessary to put the White Lightnin or whatever other strop dressing that you are using, on the strop each time you use it. One application is sufficient to do 50 100 blades.
There are dozens of youtube videos on sharpening too - some better than others
