My dad always had extremely sharp knives which he sharpened on a whetstone with oil. He tried teaching me but I have never been especially good at sharpening knives.

So, any better/easier way? I am not thrilled with our collection of crappy dull knives.
 
I'm a big fan of thin bladed crappy soft steel kitchen knives. They rust if you let them, but a sharpening steel gives them a good edge right post hasty - like under 10 seconds - and it doesn't take an extended set of stones or any kind of skill to use a steel. Don't care for stainless blades because a steel doesn't work on them.
 
You can take them to a lot of supermarkets and ask the butcher to sharpen them. You'll have better luck with that at the more expensive high end markets.

Also check your yellow pages. Lots of professional knife sharpeners in major cities. They'll sometimes come to your house and do it at the curb out front while you wait for a few bucks extra.

Or get one of these...

I've had its predecessor for almost 20 years. The little "sharpening steel" included with a knife set will straighten an existing edge but wont do a very good job of putting a new one on. This little electric job has a set of magnets in it that keep the blade aligned. About 15-20 passes through each progressive 'notch' and you've got a brand new edge that'll stay on there with a bit of maintenance for a month or more.
 
A lot depends on the quality of the knives. I'm assuming yours are normal, less than high quality knives. If so, one of those slide-the-blade-through-the-slot sharpeners will do fine. They come manual or electric. I don't know what the difference is. As stated above, a kitchen steel is pretty effective and easy too.

If you have good quality knives or are just into sharp knives (like me), get a set of diamond abrasive sharpening stones. It's a fun way to multitask while watching TV. :)
 
I've never been all that great at sharpening knives using a whetstone either, but during my brief career as a dishwasher one of the cooks taught me how to use a sharpening steel - so that's my preferred method.

Here's a link to a video that demonstrates the process fairly decently. Sharpening A Knife With A Steel

One thing I learned just a few years ago is that you should never-ever wash good knives in a dishwasher. The chemicals etch the steel and over time you can turn a good knife into trash.

If your knives are salvageable, take them to a butcher and ask him to sharpen them for you. Keep them out of the dishwasher and just touch them up with a sharpening steel each time you get ready to use one (takes a few seconds once you get the hang of it) and you should be good for years.

Your last alternative might be either an electric kitchen knife sharpener, or a little ceramic sharpener like this.

I have one of those that I use while hunting, but I use cheap knives for that purpose.

The only problem with electric or ceramic sharpeners is that knives sharpened that way don't hold an edge for very long.

I have to drive 160 miles to get to a high end market. :)

Maybe. Wish it wasn't so pricey.

Yeah, just general old middling knives. I do like them sharp and have good stones from my dad, but I am no good at sharpening.

I admire people who can really sharpen knives with a whetstone. I am not one of them.

My son gave me a few Global knives, and a ceramic sharpening jig for them. My knives are like razors now! Here is this one:

For my older knives that are not Global I bought a little tool that costs about $5 and has a finger guard that does a pretty good job. I finish these off with a quality steel.

This one is not exactly the same as mine, but same design.

I got one of those ceramic thingies and it doesn't seem to work well for me. Maybe my knives are too far gone.
 
It was always a badge of honor if your pocket knife could shave the hair off your arm...
 
Yeah that units a little expensive but they last forever. Americas test kitchen did a review on a bunch of them and said that one was the only thing they tried that didnt suck or cost more than a brazillion dollars.

I think the sharpening steel you are referring to straightens out the edge (the edge rolls over); it does not sharpen the knife.
 
Most kitchen knives are sharpened to a double beveled edge, I think. A steel will only help put the edge back on a blade that is already in good shape. Once they get dull, the blade needs to be 'thinned'. You get worn down to the thick part, and it just sort of rounds off at that point.

I've got an older version of that Spyderco that Dex linked - it works well, but if the knife gets really dull, I still need to use a stone or sandpaper to get it thin again, so it will 'take' an edge.

I've had good luck with wet/dry sandpaper, water and a drop of detergent on a flat surface (some people use a small sheet of glass). Cheap, and you can work your way from 320,400,600,etc down to 1200 and get a very nice edge.

search 'scary sharp' and sandpaper

You need to understand the two bevels, that seems to be key, at least in my experience. So first you 'thin' it like in the V-Edge drawing, but thinner, then you add the second bevel - that's the part that is really sharp. Here's a pretty good site and drawing:

I bought a diamond ceramic sharpener made by Buck for under $30 from a knife supply place. It works really well, is easy, and now my expensive German knives are like razors. Still haven't figured out how to sharpen the ceramic knife, though.
 
You can sharpen knives by using the edge of an old pottery bowl. My now deceased mother-in-law grew up in tough times and taught me that. It works for me.
 
Being frustrated by dull knives and other cutting tools, and unable to find anything that worked well, years ago I bought a Tormek Super Grind. SharpToolsUSA - Tormek. Kind of pricey at $600+ then, but it sharpens knives and just about anything else literally razor sharp. It's a wet wheel turning in a trough of water and the other side has a leather wheel wetted with mineral oil and fine grinding paste.

Forget shaving the hair off your arm. The knife is sharp when you can shave layers off your fingernail.

Let's turn the problem around-- maybe you're trying to cut tough objects. If you don't do that anymore then you wouldn't need to sharpen the knives.

As for the thinly-sliced meats used in stir-fry... we order Chinese or Korean take-out.

Our knives aren't used for much more than a piece of steak or a roast turkey-- or a tomato. One of them is from my mother's kitchen and must be 50 years old by now, and our set of steak knives was a wedding present over 22 years ago.

We wash them all in the dishwasher, too.

Unless it's really really entertaining, perhaps the amount of time required to sharpen them is greater than the cost of buying a few new knives.
 
spydercos makes a foolproof system linked in dex's post. i have it and its great. very versatile as well.


As far as shaving with a knife as a badge of honor...that WAS my gold standard before really getting into knives. Now the blade must 'pop' the hairs up an inch or 2 for me to be satisfied
 
We heard a bell ringing in front of our house a couple of months ago and half an hour later six of our knives were honed to a scary level of sharpicity for $10 by this gentleman (that's my slicer he's working on now):

I love the juxtaposition of these sequential posts. From broken pottery to a $600 sharpener. And I'd bet the pottery bowl works quite well, as long as you get the proper angles to get that double bevel. I've even used the cement floor to put an edge on a dull razor knife - not the best but it was sharper than it was before.

PS - the 'scissors man' used to come around my great-aunts old neighborhood in Chicago when I was a kid. I figured they were history by now. nice pic :)
