Miracle Blade sets were a staple of late-night TV, with demonstrations of knives cutting tomatoes, frozen food and even shoes. Many households still have a set in a drawer.
This review looks at what the knives actually do well, which marketing claims hold up and whether they’re worth buying today.
What Are Miracle Blade Knives?
Miracle Blade is an infomercial knife brand sold in sets that typically include a large slicer, a chopping cleaver-style knife, a filleting knife, a paring knife, steak knives and kitchen shears. Most blades are serrated stainless steel with plastic handles.
Several versions have been sold over the years, including Miracle Blade III and the World Class series. Contents, prices and guarantees vary by version and seller.
Claims vs Reality
| Claim | Reality |
|---|---|
| Never needs sharpening | Serrations dull slowly, but they do dull |
| Cuts through anything | Fine for food; bones, frozen food and hard objects damage edges |
| Lifetime guarantee | Terms depend on version and seller; registration may be needed |
| All the knives you’ll ever need | Useful set, but lacks a precise plain-edge chef’s knife |
A 2002 “Does It Work?” segment by Hawaii News Now found that Miracle Blade III cut tomatoes and onions easily and survived rough tests. The reviewer concluded the knives lived up to some, but not all, of the claims.
Our older review repeated the “never need to sharpen” claim and said the knives “are never dull”. That isn’t accurate for any knife, so we’ve corrected it.
What Miracle Blade Knives Do Well
Serrated edges grip and saw through tough skins and crusts, so the knives slice tomatoes, bread, citrus and cooked meat easily. Because the recessed scallops touch the board less, they keep working long after a plain edge would feel dull.
The sets are cheap, cover many tasks and are easy to replace. For a rental, a dorm or a camping kit, that’s a real advantage.
Where They Fall Short
Serrated knives tear delicate food and make it hard to get clean, precise cuts in onions, herbs and raw fish. Most Miracle Blade sets lack a good plain-edge chef’s knife for everyday dicing and mincing.
The steel is basic stainless, the handles are lightweight plastic and owners often report rust spots and dulling over time. They don’t compare with established brands like Wüsthof or Henckels.

Miracle Blade vs a Basic Good Knife
| Miracle Blade set | One good chef’s knife + bread knife | |
|---|---|---|
| Cost | Low | Low to moderate |
| Edge | Mostly serrated | Plain chef’s knife, serrated bread knife |
| Precision | Limited | High |
| Sharpening | Hard on serrations | Easy on the chef’s knife |
| Best for | Rough, everyday slicing | Real cooking |
For the same money, many cooks would be better served by a budget plain-edge chef’s knife and a serrated bread knife. See our best chef’s knives under $100 for options.
Who Should Buy Miracle Blade?
Miracle Blade sets suit rentals, holiday homes, camping kits, students and anyone who wants a cheap, complete set they won’t worry about. They’re also handy as backup knives for heavy, messy jobs.
Keen home cooks will soon want at least one good plain-edge chef’s knife alongside them.
How to Sharpen Miracle Blade Knives
Serrated Miracle Blade knives can be sharpened, one scallop at a time, with a tapered ceramic or diamond rod. Outdoors site Outdoor Life’s guide on sharpening a serrated knife explains the technique.
Food site Chowhound’s serrated knife sharpening explainer also warns against grinding serrations flat in a standard pull-through sharpener. For step-by-step help, read our guide on the best way to sharpen a Miracle Blade.
Because the knives are inexpensive, some owners simply replace a dull knife. That’s a reasonable choice for budget sets.
Caring for Miracle Blade Knives
- Hand-wash and dry immediately to prevent rust spots.
- Avoid cutting bones, frozen food and hard objects, whatever the infomercial showed.
- Store knives safely in a block or with guards.
- Use a wooden or plastic board, never glass or stone.
- Replace badly rusted or damaged knives rather than struggling on.
The Guarantee
Miracle Blade has been sold with lifetime guarantees, but terms have varied by version and seller, sometimes requiring registration and covering only the original buyer for household use. Check the terms that came with your set before relying on them.
What’s Usually in a Set?
Miracle Blade sets have typically included a large all-purpose slicer, a “chop and scoop” cleaver-style knife, a rock-and-chop knife, a filleting knife, a paring knife, several steak knives and kitchen shears. Some versions add a block or extra steak knives.
The variety looks impressive, but several pieces overlap. Most cooks end up using the slicer, the paring knife and the steak knives most.
Are the Steak Knives Any Good?
The serrated steak knives are one of the stronger parts of the set. Serrations handle cooked meat well and survive contact with plates, so they stay usable for a long time.
If you mainly want inexpensive steak knives, compare them with our best serrated steak knives guide.
Our Verdict
Miracle Blade knives are inexpensive, practical serrated knives that do a fair job on everyday food. They’re not the miracle the ads suggested, and they don’t replace a good plain-edge chef’s knife.
Buy them as a cheap starter or backup set; for real cooking, add one quality chef’s knife.
Why Serrated Sets Feel So Sharp at First
Serrated knives feel very sharp out of the box because the points bite into food immediately. Even when the edges between the teeth wear, the points keep cutting, which is why the knives seem to stay sharp for a long time.
Eventually the points round over too, and the knife starts to tear and crush. That’s when it’s time to sharpen or replace it.
Safety Tips
Serrated knives can slip on hard, round foods like squash or melon. Cut a flat side first so the food sits steadily, and always keep your guide hand in a claw grip.
Final Buying Tip
If you buy a Miracle Blade set today, check which version you’re getting, what’s included and what guarantee applies. Older sets sold second-hand may not carry any guarantee at all.
