How to keep your knives razor sharp?

Published on 1 August 2025 at 16:26

One of the most important parts of owning a good blade: keeping it sharp! There's a common saying that a dull knife is more dangerous than a sharp one, and it's absolutely true. A sharp blade bites exactly where you want it to, while a dull one can slip, causing a nasty accident. So, let's dive into the world of razor-sharp edges and how to achieve them.

Honing vs. Sharpening: What's the Difference?

This is the most common point of confusion, and for good reason! The terms are often used interchangeably, but they refer to two very different processes. To put it simply: You sharpen to fix a dull blade, and you hone to maintain a sharp one.

  • Sharpening is about removing material from the blade to create a new, fresh edge. Think of it like taking a little bit of steel off the edge to expose a brand new, pristine cutting surface. When you sharpen, you're correcting damage, chips, or simply a completely worn-out edge. This is a more aggressive process and isn't something you do every day.

  • Honing, on the other hand, is about realigning the existing edge. As you use a knife, the super-thin, microscopic edge can bend and roll over. This makes the knife feel dull even though no material has been lost. Honing simply straightens that edge back out, so it's perfectly aligned to slice through whatever you're cutting. It's a quick tune-up, not a full-on overhaul.

When & How Often to Sharpen?

This really depends on how often you use your knives. For your typical home cook who's in the kitchen a few times a week, a good rule of thumb is to sharpen your knives every 6 to 12 months. This keeps them in tip-top shape. However, if you're processing a deer out in the bush or doing some serious prep for a big BBQ, you might need to sharpen more frequently.

As for honing, this is something you should do much more often. A few passes on a honing steel before each use will keep that edge aligned and feeling like new. It only takes a minute and makes a huge difference in your cutting experience.

Using a Sharpening Stone or Steel

  • Sharpening Stone (Whetstone): This is the classic, time-honoured method. Using a whetstone gives you the most control and lets you truly understand your blade's geometry. You'll typically use a coarse side to establish the edge, and then a finer side to polish it. The key is to maintain a consistent angle. For most kitchen knives, a 15-20 degree angle is a good place to start. A great technique is to imagine a permanent marker line on your edge and use the stone to remove that line evenly.

  • Honing Steel: This long, rod-like tool is what you see chefs using on TV. It's for honing, not sharpening. To use it, hold the steel vertically with the tip on a cutting board. Place the heel of the blade against the top of the steel at a 15-20 degree angle. Then, draw the knife down the steel in a gentle, arcing motion, pulling it toward you as you go. Alternate sides for about 6-8 passes on each side. The goal is to realign, not grind.

Recommended Frequency for Home Cooks

For the average home kitchen knife, I'd suggest a simple routine:

  • Hone: Give your favourite chef's knife a few passes on a honing steel before you start every meal prep session. This is the single best habit you can adopt to keep your knife feeling sharp.

  • Sharpen: For regular use, aim to sharpen your most-used knives every six months. If you notice your knife slipping on a tomato's skin or struggling to slice cleanly, it's definitely time for a professional blade sharpening service to get that edge back.

For a Professional Edge: Bench-Clamped Sharpening Systems

If you want a truly professional, repeatable, sharp edge, then a bench-clamped sharpening system is a game-changer. These systems hold the knife securely in a clamp and use guide rods to ensure you maintain a perfect, consistent angle every time.

These systems are fantastic because they remove all the guesswork. You choose your angle, lock it in, and then use different grits of stones to create and refine the edge. It's the best way to get a flawless, symmetrical edge that will slice through anything. While a traditional whetstone is an art form, these systems are pure science.

Whether you're a seasoned hunter or just love cooking for the family, keeping your knives sharp is a simple act of respect for your tools and your craft.
