Should a Restaurant Sharpen Its Own Knives? (The Honest Pros and Cons)

Every chef has stood in a dull kitchen and thought, "How hard can it be? I'll buy a stone." It's a great idea. It's also how a lot of chefs end up sharpening knives at midnight.

Let's get the short answer out of the way, because you have a lunch rush.

Yes, a restaurant can sharpen its own knives. It works when one skilled person has time for it every single week. Most busy kitchens don't have that person, so they pay a service and hone in between.

That's it. That's the post.

Okay, fine, here's the rest of it.

Can a restaurant sharpen its own knives?

Absolutely. Plenty of great kitchens do. A whetstone, some water and a patient human can put a beautiful edge on a chef's knife.

The catch is the word "patient." And the other word, "human."

Sharpening by hand is a real skill. It takes practice to hold the same angle stroke after stroke, raise a burr, and take it off cleanly. Done well, it's lovely. Done by someone who watched one video, it's a knife that cuts great on the left side and like a spoon on the right.

And even a pro needs time. Not once. Every week, forever, for every knife on the line.

The pros of sharpening in-house

Let's be fair to the stone. It has real upsides:

If your kitchen runs a handful of knives and has one person who loves sharpening, honestly, keep doing it. You might not need us.

The cons nobody puts on the whetstone box

Here's where it gets real.

And here's the big one. The person who's good at sharpening and the person with free time are almost never the same person.

Pros and cons of outsourcing knife sharpening

Now the other side. Paying a service has its own trade-offs, and we're going to tell you them even though we are, technically, the service.

The pros:

The cons:

The math (bring a calculator, or don't)

Here's a simple way to compare. Use your own numbers. We'll use made-up round ones.

Say your line runs 10 knives. Say each one takes 12 minutes to sharpen well on stones. That's 2 hours a week of somebody's paid time, plus stones, plus flattening the stones, plus the weeks it doesn't happen because two people called in.

Now put that next to a weekly visit:

New-customer route prices, per visit. Knife swap and multi-location groups are quoted.

For most kitchens, two hours of a skilled cook's time costs more than the visit. And the visit doesn't call in sick.

Two hours of a cook's time weighs more than one truck stop.

The answer most kitchens land on: both

Here's the secret. It's not really either-or.

Honing is the daily part. A few strokes on a steel straighten an edge that's bent over from use. It takes seconds, any cook can learn it, and it makes an edge last longer between sharpenings. (Here's how to hone a knife properly.)

Sharpening is the weekly part. It removes a little metal and makes a brand-new edge. That's the skilled, slow part, and it's the part worth handing off.

Hone every day. Sharpen every week. Let someone else do the slow part.

When you should keep doing it yourself

We promised honesty, so here's when we'd tell you to skip us:

For everyone else (the kitchens where knives get sharpened "when somebody gets to it"), a schedule beats good intentions every time.

Questions chefs ask

Should a restaurant sharpen its own knives?
It can, if one skilled person has time to do it well every week. Most busy kitchens don't, so they use a sharpening service for the weekly sharpening and have cooks hone on a steel every day in between.
What are the pros and cons of outsourcing knife sharpening for a restaurant?
Pros: no staff time, a set schedule, consistent edges, and help with slicer blades and damaged knives. Cons: a weekly cost, trusting someone with your knives, and some services that lock you into long contracts or rental programs. Ask about all three before you sign.
How long does it take to sharpen a knife on a whetstone?
For someone skilled, a dull chef's knife often takes 10 to 15 minutes to sharpen well by hand. A whole line of knives can eat a couple of hours a week.
Is honing the same as sharpening?
No. Honing straightens an edge that's bent over and takes seconds. Sharpening grinds a new edge and takes real time. Hone daily, sharpen weekly. See how to hone a knife.
How much does a restaurant knife sharpening service cost?
Our restaurant routes start at $45 a visit for 10 knives, plus a $5 fuel charge. Knife swap service is quoted on how many knives your line runs. More in our knife sharpening cost guide.
Do I have to sign a long contract?
Not with us. We publish our prices, you keep your own knives, and the same driver comes every week. If something isn't right, tell your driver or call (214) 701-5564 and we re-do it.
