Quick Summary
- Serrated edges grip and saw through tough or slippery surfaces like bread crust, tomato skin and rope.
- Plain edges make clean push cuts and give more control for dicing, peeling and carving.
- Serrated edges stay usable longer but are harder to sharpen at home.
- Partly serrated blades combine both, but each section is shorter.
- In the kitchen, most cooks need a serrated bread knife and a plain-edge chef’s knife.

Every knife edge is either plain (straight), serrated (toothed) or a mix of both. Each cuts differently, and choosing the right one makes a real difference to how easily you work.
What Is a Serrated Edge?
A serrated edge has a row of scallops or teeth. The points bite into a surface and the scallops slice as you saw back and forth.
Because the points concentrate pressure, serrated edges cut well through tough skins and crusts that make a plain edge slip. They also keep working when slightly dull, since the recessed edges between the teeth touch less.
What Is a Plain Edge?
A plain edge is one continuous sharp line. It’s the standard for chef’s knives, paring knives and most pocket knives.
Plain edges excel at push cuts, where you press straight down or forward through food. They give clean, precise cuts and are easy to sharpen on almost any tool.
Serrated vs Plain Edge Compared
| Serrated | Plain | |
|---|---|---|
| Cutting action | Sawing | Push cut or slicing |
| Best for | Bread, tomatoes, citrus, rope, fibrous material | Vegetables, herbs, meat, peeling, whittling |
| Cut quality | Can tear soft foods slightly | Clean, precise |
| Control | Lower | Higher |
| Edge life | Stays usable longer | Needs more frequent honing |
| Sharpening | Slow; needs a tapered rod or pro | Easy with any sharpener |
Knife retailer A.G. Russell’s article on serrated vs plain edges sums it up well: serrations win on tough or fibrous material, plain edges win on push cuts and control.
Serrated vs Plain in the Kitchen
Most kitchens need both. A serrated bread knife saws through crusty loaves without crushing the soft crumb, and it handles tomatoes, peaches and citrus with ease.
Our pick in the best bread knife guide includes the Tojiro F-687 Bread Slicer, a long, sharp serrated blade.
A plain-edge chef’s knife handles nearly everything else: dicing onions, mincing herbs, slicing meat and chopping vegetables. Steak knives are commonly sold in both styles; see our best serrated steak knives for the trade-offs.
Serrated vs Plain Outdoors
On pocket and outdoor knives, serrations help cut rope, webbing, seat belts and fibrous plants. A plain edge is better for whittling, food prep, skinning game and fine control.
Many outdoor users prefer a plain edge because it’s easier to sharpen in the field. Others carry a partly serrated knife for flexibility.
Knife maker Tekto’s guide to serrated vs plain edges suggests a plain edge if you carry one knife, and a serrated one as a second tool for rope and webbing.
Partly Serrated Blades
A partly serrated or combo blade usually has serrations near the handle and a plain section toward the tip. It covers both jobs but gives you a shorter stretch of each edge.
UK knife retailer Heinnie Haynes’ guide to plain, serrated and part-serrated edges notes the same compromise, and points out that the serrated section is often short.
How to Sharpen Each Type
Plain edges can be sharpened on a whetstone, honing rod, guided system or pull-through sharpener. See our guide on how to sharpen kitchen knives for step-by-step help.
Serrated edges are sharpened one scallop at a time with a tapered ceramic or diamond rod, working only on the beveled side. It’s slow, so many people send serrated knives to a professional.
The good news is that serrated knives need sharpening less often. A quality bread knife can go years between sharpenings in a home kitchen.
Myths About Serrated Knives
Our older article claimed serrated knives are “made for cutting through bones” and recommended them for self-defense. Neither is right: bones need a cleaver or saw, and knives should be chosen for cooking and practical tasks.
It also said serrated knives are “not very sharp”. A good serrated edge is sharp; it simply cuts with a sawing motion instead of a push.
Which Should You Choose?
| Your main task | Best edge |
|---|---|
| Bread and crusty rolls | Serrated |
| Tomatoes and soft fruit | Serrated or a very sharp plain edge |
| Everyday chopping and dicing | Plain |
| Carving roasts | Plain (long slicer) |
| Rope, webbing, cardboard | Serrated or partly serrated |
| Whittling and food prep outdoors | Plain |
How Serrations Differ
Not all serrations are alike. Bread knives usually have wide, rounded scallops that glide through crust without tearing the crumb.
Steak and utility knives often have smaller, pointed teeth that grip cooked meat. Some cheap knives use tiny micro-serrations that can’t be resharpened, so they’re best treated as disposable.
Testing Which Edge Suits You
Try slicing a ripe tomato and a crusty loaf with both edges. You’ll quickly feel where the serrated edge grips and where the plain edge glides.
Then try dicing an onion. A sharp plain edge gives neat, even pieces, while a serrated edge tends to tear the layers and leave ragged cuts.
Most cooks end up keeping both: a long serrated knife for bread and a plain chef’s knife for everything else. That pairing covers nearly every kitchen task.
Why Serrated Knives Feel Sharp for So Long
On a serrated blade, only the tips of the teeth touch the cutting board. The recessed scallops stay protected, so they keep cutting long after a plain edge would feel dull.
That’s why bread knives seem to last forever, and also why cheap serrated knives can hide a poor-quality edge for a while.
Care Tips for Both Edges
Hand-wash and dry both types straight away, and keep them away from the dishwasher. Cut on wood or plastic boards, never glass or stone.
Hone plain edges regularly. For serrated edges, a few light passes with a fine ceramic rod on the beveled side remove small burrs between sharpenings.
Edge Choice for Pocket Knives
For everyday carry, a plain edge is the most versatile choice for most people. It opens packages, slices food and whittles wood, and it’s easy to touch up on a small stone.
If you regularly cut rope, straps or fibrous plants, a fully or partly serrated blade may save you effort. Fishermen and sailors often prefer serrations for cutting line and rope.
Our Verdict
For precise, everyday cutting, a plain edge is the better all-rounder. For crusty bread, tough skins and fibrous material, a serrated edge does the job with less effort.
In the kitchen, keep one of each; outdoors, choose based on whether you’ll cut more rope or more food.
Frequently Asked Questions
Is a serrated or plain edge better?
Neither is better overall; serrated suits tough surfaces, plain suits precise push cuts.
Do serrated knives stay sharp longer?
They stay usable longer, because the points do most of the work.
Can you sharpen a serrated knife?
Yes, with a tapered rod one scallop at a time, or by a professional.
Should steak knives be serrated?
Either works; serrated needs less maintenance, plain gives cleaner cuts.
Is a partly serrated knife a good idea?
It’s handy outdoors, but you get a shorter length of each edge type.
