How to Properly Sharpen Serrated Knives at Home

**Collaborative post**

Serrated knives are essential in every kitchen for cutting breads, tomatoes, sandwiches, and many other foods cleanly and easily. However, like all knives, the serrated edge can gradually become dull with repeated use. Rather than living with a blunt serrated knife or trying to saw through foods, you can easily sharpen these speciality knives at home.

Sharpening serrated blades requires just a bit of patience, the right tools, and proper technique. With some care and minimal effort, you can extend the working life of your expensive serrated cutlery. 

Here is a guide to effectively sharpening serrated knives in your home kitchen.

How Serrated Blades Work

Before learning to sharpen, it helps to understand what makes a serrated edge special. The key benefit lies in those neat rows of sharp teeth or points:

• The teeth allow the blade to cut into food while requiring very little downward pressure. This helps preserve the structure and texture of soft fruits and breads.
• The gaps between the teeth allow food particles to escape so that the blade does not get weighed down or stuck inside dense foods. This enables smooth, continuous slicing motion.
• The somewhat coarse nature of the edge enables it to penetrate tough exteriors more easily, without damaging interiors. This makes serrated knives perfect for slicing tomatoes and sandwiches.

Signs Your Serrated Knife Needs Sharpening

Serrated knives stay sharp much longer than plain-edged blades which need frequent honing. However, serrated edges also gradually become blunt with extensive use. The following are some of the most common signs that your bread knife or other serrated blade needs some sharpening attention:

• You need to apply extra hard pressure to cut through foods, especially soft items like ripe tomatoes or crusty bread.
• The serrated edge feels smooth instead of being able to feel the individual teeth points.
• Food bits get lodged inside the valleys between teeth and are tricky to clean out.
• The knife stops slicing cleanly and starts shredding or tearing food instead.
• Jagged edges or damaged points are visible under close inspection.

Ignoring these warning signs and using a dull serrated knife can be unpleasant as well as unsafe. This is because, with a dull knife, you have to use more force to do the simplest of cutting tasks. So, sharpen those teeth before it becomes a frustrating, struggling chore to slice anything!

Best Tools for DIY Serrated Knife Sharpening

While you can use sharpening stones or files, serrated knives sharpen best with these specialized tools:

• Diamond sharpening rods – The diamond coating on these manual rods can sharpen each individual micro-serration along the length of the blade. Diamond rods come in fine, medium and coarse grits. And if you are to choose one, then the medium grit is ideal.
• Electric or manual pull-through sharpeners – Quality serrated knife sharpeners have pre-set angles to match knife edges. The motorised or manual sharpening wheels straighten and re-bevel teeth.
• Honing oil (optional) – Applying some honing oil or lubricant allows the sharpening rods to glide smoothly over the serrated ridges without hanging up.
• Magnifying glass or eye loupe – A small magnification lens allows extremely close inspection so you can check if the teeth are evenly sharpened.

Step-by-Step Technique to Manually Sharpen Serrated Knives

Follow these key steps to sharpen serrated blades using a diamond rod:

1. Rinse the knife and dry thoroughly with a towel. Remove any food bits lodged between teeth.
2. Apply 2-3 small drops of honing oil along the rod. This optional step provides smooth glide lubrication.
3. Tilt the edge against the rod at the same angle as the blade edge – around 20° for most knives. Grip the handle firmly.
4. Using minimal pressure, gently pull the length of the blade along the rod. Use fingernail pressure and allow the diamond abrasive to do the work.
5. Flip the knife and repeat back-and-forth strokes along the opposite side of the serrated edge, from handle to tip.
6. Sharpen 5-6 strokes on each side of the blade. Then check by gently touching the edge to feel for sharpness.
7. Rinse the blade and dry thoroughly before storing.

With a fine or medium diamond rod, most serrated blades only need 6-8 gentle strokes on each side to restore sharpness. Avoid using too much muscle or you can damage the delicate teeth.

Getting Professional Serrated Knife Sharpening

While manual sharpening at home provides adequate maintenance between uses, serrated knives should still receive periodic professional sharpening every couple of years. The sharpening experts use speciality machines and precise techniques such as:

• Ceramic grinding wheels – Spinning ceramic rods reshape teeth to their original specs and create razor-sharp micro-edges.
• High grit belts – Flexible abrasive belts straighten bent teeth, polish roughness and refine the edge.
• Precision guides – Angled guides ensure correct bevel angles along the length of the serrated edge.

This reconditioning restores knife performance to like-new. The pros also inspect for any cracks or defects needing repair.

So while learning to sharpen your own serrated knives at Sakuto Knives helps for quick touch-ups, the blades still need deeper professional sharpening services every 24-36 months.

Key Tips for Serrated Knife Care & Handling

Along with proper sharpening, just a bit of care in use and cleaning helps serrated knives retain edges better between sharpenings:

• Always cut on a clean cutting board, never directly on plates.
• Use smooth stroking motion without twisting or see-sawing when cutting hard items.
• Avoid using serrated knives for prying, hacking or chopping tasks. Use only for intended slicing purposes.
• Clean by hand with gentle dish soap, a soft sponge and hot water. Avoid aggressive scrubbing of the blade edge and teeth.
• Consider covering stored serrated blades with knife guards to prevent accidental damage.

With the right sharpening tools and by following these serrated knife handling guidelines, your specialised knives should stay sharp and deliver top performance for many years.

So revive dull serrated knives now and make meal preparation easier. Sharpening serrated blades at home helps ensure your knives slice beautifully through all kinds of breads, ripe tomatoes and delicate foods requiring a finessed touch.
