How To Sharpen a Knife

2009_5_6-sharpen-knife.jpgTaking part in the Kitchen Cure? This would be a great week to learn how to sharpen your knives, especially given all the cooking you'll be doing in the final three weeks. Even if you're not one of the 800 plus Cure-takers, my guess is your knives haven't been sharpened lately, if ever.

First a quick survey, then click through for a great how-to video on knife sharpening.

 
 

You'll need a sharpening stone (or bench stone) for sharpening and a sharpening steel (or rod) for honing. For stones, I like one with a diamond edge, but it's not necessary for sharpening success and non-diamond stones will only set you back less than $10. For the steel, they are usually included in knife sets, or pick one up for less than $20 at most cook's supplies.

Here's Marc Bauer of the French Culinary Institute demonstrating the method I learned (as a student at FCI, although not from Chef Marc.)



After you watch the video, read Emma's step-by-step post on how to sharpen your knives.

A note on frequency: Professionals sharpen their knives a lot more often than home cooks. I cook at home often, probably using my chef's knife at least four times a week, so that is a knife I sharpen on a stone about four times/year. I hone it on the steel almost every time. Once you work with a properly sharpened knife, you'll know when it needs to be sharpened again. Honing re-aligns the blade whereas sharpening on a stone actually scrapes off a little of it, so obviously you want to hone more often than sharpen.

2009_5_6-knife-sharpeners.jpg• Pick up this inexpensive sharpening steel (Cooking.com, $13.95) and Smith's Diamond Sharpening Stone (Amazon, $24.45) or this budget-friendly Silicon Carbide Sharpening Stone (Restaurant Source, $2.23)

I am curious, if the diamond edge stone is not necessary for sharpening, why use it? I would lean toward the budget friendly stone unless there is some added bonus the diamond edge stone provides. It's wasn't addressed in the video. Can someone let me know?

I REALLY need to sharpen my beloved knives and will be heading out for one of these stone styles once I know.

I've heard that Japanese knives should not be honed, and they require sharpening on a special stone. So I haven't done anything with my Togiharu yet; I may just mail it somewhere because I don't want to risk ruining it. But I do have a regular chef's knife that I keep in good shape.

I have almost all these sharpening tools, plus a Chef's Choice, and I recently bought an Accusharp 001 Knife Sharpener. It was ~$10 at Amazon. It works very quickly (takes about 1 minute to sharpen even a very dull knife) and does a surprisingly good job. My conclusion: it's something that every "everyday" cook should at least try - it might end up being the only sharpener you need. I've even used it on serrated knives to good effect.

Some knives, like the ones made by Global, and Shun require the use of a ceramic honing wand (traditional wands are steel), Sjbreeze, maybe that's the difference in your Japanese knives. It should say some where on their manufacturer's website although sometimes the only clue is which one the sell in the sets. I'm not sure about the Damascus knives though.

Does anyone know what 'grit' of sharpening stone we should be useing to sharpen our knives at home?

For whatever strange reason, I'm afraid of sharpening my own knives. And I know I'm probably just making it worse by continually using them un-sharpened/honed.

I'm going to watch this video at home later and just suck it up and try it.

I’ve been paying to have my knives professionally sharpened, but I’m feeling inspired. There’s really no reason for me to do it myself.

Global's don't require a ceramic honing wand. I have a lot of global knives, and a nice global steel wand that has worked great for the past 7 years.

I use the Accusharp mentioned by manjar. Just whenever I think to do it. Seems to make the knives sharp enough, but what do I know?

i'm a scaredy cat. if my knife cut a piece of paper like in the video, i'm sure i'd be missing several fingers by now.

i know a sharper knife is supposed to be safer than a dull one because you don't have to use as much pressure, etc, BUT that assumes that you haven't ingrained YEARS of dull knife usage into your repetoire. :)

Correction to my post above -
i meant there's no reason for me to NOT start doing it myself!

After like 20 years, I finally got around to buying a stone and learning this a few months ago. I can't believe it took me so long, because it turns out it's pretty easy. I'm not good enough to be able to get them paper cuttting sharp yet, but what I can do is a huge improvement over my the seriously sad state that my knives used to be in. I went with a two sided Arkansas whetstone for like $6.

Can someone explain the differences between the types of steels (ceramic v. diamond cut) and the types of stones? I understand the grit factor, but why do they range in price from $3 to $50 or more? I don’t want to buy a budget set if they’ll be harder on my knives. Also, are different kinds better for different blades? My knife set includes Global, Shun, Wustof, and Chicago. Can I use the same steel and stones for all? I’m guessing they do when I have them professionally done, but that’s just a guess.

I get nervous about honing my knives. I guess I think I will do it incorrectly and ruin them or something. I let my husband do it. And I take them to a local shop to be sharpened every once in a while. It only costs a few bucks per knife.

Hey splatgirl can you tell me where you got your arkansas whetstone and if it has a specific name? Can I get it at any hardware store?
Thx!
