What You’ll Learn
- Why serration matters.
- What blade length works well.
- How handle design affects control.
- Why flexibility matters.
- When to sharpen or replace the knife.
Quick Answer
For sourdough, choose a long serrated knife with a comfortable handle and enough blade length to span most of the loaf. A blade around 20–25cm is practical for many home loaves.
This lesson is part of our Equipment section: “Choose tools that genuinely help.”
Why Serrated Blades Work
The teeth grip and cut through crust without needing excessive downward force.
Blade Length
A longer blade reduces awkward sawing on wide loaves.
Handle Comfort
A secure handle improves control, especially on very crusty bread.
Blade Flex
Some flexibility is useful, but too much can make straight cuts harder.
Maintenance
Serrated knives are harder to sharpen at home, so quality and durability matter.
Cutting Technique
Use a gentle sawing motion rather than pressing down.
From Our Workshop
A sharp bread knife protects the loaf you just spent a day making.
Bake Slower Tip
Let the loaf cool fully before slicing; even the best knife cannot fix gummy hot crumb.
Common Mistake
Do not force a blunt knife through crust with heavy downward pressure.
Today You Learned
- Use a serrated blade.
- 20–25cm is a practical length.
- Handle comfort matters.
- Gentle sawing protects crumb.
- Sharpness is important.
Frequently Asked Questions
Can I use a chef’s knife?
You can, but serrated knives usually handle crust better.
How long should the blade be?
Long enough to span most of your loaf.
Can serrated knives be sharpened?
Yes, but they often need specialist sharpening.
Why does my loaf squash when slicing?
The knife may be blunt or the bread may still be warm.
Do I need an expensive knife?
No, but a good sharp blade is worth having.

Choose Tools That Earn Their Place
A good knife is less about prestige and more about protecting the crust and crumb.

Before you buy
Buy for the job you repeat most often. Size, heat tolerance, ease of cleaning and how the tool fits your usual loaf matter more than owning the most specialist version. If something you already own performs the same job safely, use it first.
