The "Knife Blunting" Fear
If you love cooking, you’ve probably heard the golden rule of knife care: Never cut on glass, granite, or metal.
For years, this was good advice. Traditional metal surfaces (like stainless steel benchtops) are brutal on delicate knife edges. They cause "edge rolling," blunting your expensive Japanese steel in seconds.
But recently, Titanium Chopping Boards have taken the kitchen world by storm, and the number one question we get at Life Upgrade Co. is: "Will this ruin my knives?"
The short answer? No.
The long answer lies in the science of metallurgy. Let’s break down why Titanium is the exception to the rule.
The Science: Why Titanium is "Soft" (In a Good Way)
To understand why our board is safe, we have to look at the Mohs Hardness Scale and the Rockwell Scale, which measure how resistant a material is to scratching.
Here is the simple truth: Hardness matters.
- If the cutting board is harder than your knife, the knife loses (it gets dull).
- If the cutting board is softer than your knife, the board takes the impact (the knife stays sharp).
The Hardness Hierarchy:
- Granite & Glass Boards: These are harder than steel. They will instantly crush your knife's edge. Avoid these at all costs.
- High-Carbon Chef’s Knife (Steel): This is the middle ground.
- Pure Titanium: Surprisingly, pure Titanium is softer than hardened cutlery steel.
Because our specific titanium alloy is less dense than the hardened steel of your chef's knife, when you slice down, the board "gives" slightly. You might see faint scratches on the board over time—this is a good thing. It means the board is absorbing the impact, sparing your blade.
Titanium vs. The "Bad" Boards
Why do people think metal is bad? Because they are confusing Titanium with other hard materials.
| Surface Material | Knife Friendly? | Why? |
| Glass / Marble | ❌ NO | Too hard. The blade "skates" and chips. |
| Stainless Steel | ⚠️ POOR | Slick and hard. Can cause edge rolling. |
| Plastic | ✅ YES | Soft, but breeds bacteria in deep grooves. |
| Titanium | ✅ YES | Softer than knife steel; naturally antibacterial. |
As you can see, Titanium sits in a unique "Goldilocks" zone. It offers the hygiene of metal, with the forgiveness of wood.
Why It’s The Best Board for Hygiene-Conscious Chefs
If wood is so soft, why switch? The problem with wood (and plastic) is what happens after the cut.
Every time you slice into wood, you create a microscopic ravine where bacteria, meat juices, and microplastics hide. No amount of scrubbing gets them all out.
Titanium solves the Microplastic vs. Dullness dilemma. It is robust enough to last a lifetime but forgiving enough to keep your Global or Wüsthof knives slicing tomatoes paper-thin.
The Verdict
So, do metal boards dull knives? If it's your stainless steel countertop? Yes.
If it's a Life Upgrade Co. Titanium Board? No.
You get the best of both worlds: a hospital-grade sanitary surface that respects the edge of your favourite blade.
