If you’ve ever mangled a loaf of sourdough trying to “saw” it open with a dull knife, you already know: bread deserves better. I’ve tested dozens of knives in my 10+ years working in restaurant kitchens and I’ve learned that even the most beautiful loaf can be ruined by the wrong tool.
That’s what led me to the Mercer Culinary Millennia 10 Inch wavy Edge bread knife Review. This thing’s been getting attention for being sharp, long, and surprisingly very affordable. So I decided to put it to the test. After weeks of slicing everything from crusty country loaves to delicate brioche, here’s my honest review.
What Is The Mercer Culinary M23210 Bread Knife?
The M23210 is part of Mercer’s Millennia line, an affordable, practical series designed for culinary students and professional cooks. It features:
- A 10-inch serrated blade
- Made from high-carbon Japanese stainless steel
- A textured Santoprene handle for grip
- NSF-certified for commercial use
Right away, I could tell it wasn’t a showpiece. No flashy Damascus steel. No walnut handle. But when it comes to bread knives, performance matters more than pretty.
My First Impressions: Lightweight, Sharp, and Functional
The first thing I noticed? This knife is long. At 10 inches, it’s longer than most home bread knives, and that extra length really helps with large boules or sandwich loaves. It’s also surprisingly lightweight, something I’ve come to appreciate during repetitive prep work.
I was skeptical of the plastic-looking handle at first. But after using it with wet hands (and even greasy fingers), I was sold. The grip is solid. It doesn’t slip, and it feels secure during long cutting sessions.
It reminded me of the knives we used in culinary school, no frills, but dependable. The kind of knife you actually reach for, not just admire on the wall.
How It Performed
To give this knife a fair shot, I put it through a series of real kitchen tests. I used it every day for two weeks. Here’s what I cut and what I found.
Sourdough Boule
This was the ultimate test. Thick, crunchy crust with a soft, airy crumb inside. The Mercer sliced through it in one smooth motion no sawing, no pressure. It didn’t crush the crust or tear the crumb. That’s not easy to pull off, especially at this price point.
Soft Sandwich Bread
No compression. That’s important. I’ve used knives that tear through the inside of soft bread like cotton candy. This one glided right through without squashing it. Clean, even slices every time.
Bagels & Rolls
Bagels can be tricky. The dense, chewy texture needs a sharp edge and control. The Mercer handled it with ease clean cuts, no uneven halves or “rip-and-tear” drama.
Cake Layers
I leveled a vanilla sponge with it, and honestly, I was impressed. That long blade gives you the reach you need, and the serrations aren’t too aggressive for cake.
Key Features: What Makes This Knife Stand Out?
Let’s break it down a little more technically for those of you comparing features.
10-Inch Serrated Blade
That extra blade length means you can slice through a whole sourdough without a back-and-forth struggle. The wavy serrations are spaced just right not too shallow, not too deep. They bite into crust without tearing the interior.
This is especially useful for large loaves, cakes, and layered pastries. Most home bread knives cap out at 8 inches, which often forces you into awkward angle-cutting. Not here.
High-Carbon Japanese Steel
This isn’t some cheap stainless blade. It’s made from high-carbon steel, which means it stays sharp longer and resists rust better than basic blades.
Now, it’s not super high-end steel like VG-10 or SG2 but for the price, it holds up really well. I didn’t notice any major dulling over the two-week testing period, even with daily use.
Comfortable Santoprene Handle
Ergonomics matter especially when you’re slicing multiple loaves or prepping for an event. The rubberized grip is slightly textured and shaped to fit naturally in your hand. No hot spots. No wrist fatigue.
It’s safe, even if your hands are wet or oily making it ideal for kitchen environments.
How It Compares to Other Bread Knives
I’ve tested a range of bread knives at all price levels from budget options to luxury Japanese slicers. Here’s how the Mercer stacks up.
| Knife | Blade Length | Price | Best For |
| Mercer M23210 | 10″ | Budget | Best overall value |
| Victorinox Fibrox 10.25″ | 10.25″ | Mid-range | Long-lasting edge and comfort |
| Tojiro Bread Slicer | 9.25″ | Premium | Precision and artisan-style cuts |
| Shun Classic Offset | 8.25″ | High-end | Beautiful design and control |

The Mercer offers 80% of the performance of high-end options at a fraction of the price. It’s not as beautiful or premium, but it gets the job done fast and clean.
Who Is the Mercer Bread Knife Best For?
After two weeks of use, here’s who I think will benefit most from this knife:
- Home bakers who want pro-level performance without spending a fortune
- Culinary students looking for affordable tools that meet school standards
- Commercial cooks who need a reliable, NSF-certified knife
- Cake decorators needing a long blade to level layers
It’s not the right knife for collectors or aesthetics-focused chefs. But for people who value function, sharpness, and grip this one checks all the boxes.
Pros and Cons at a Glance
