Understanding Powder Metallurgy
Both M390 and CruWear are produced using powder metallurgy, an advanced manufacturing process that significantly improves the internal structure of steel.
Traditional steel production begins by casting molten steel into large ingots. As these ingots cool, carbides can grow unevenly and form larger clusters. These coarse carbide structures may reduce toughness and make sharpening more difficult.
Powder metallurgy follows a different process.
Instead of cooling into large blocks, molten steel is converted into microscopic powder particles. These particles are then compressed and fused under carefully controlled heat and pressure to form solid steel.
This method creates a much finer and more uniform carbide distribution throughout the material.
The result is steel with several important advantages:
- Smaller carbide particles
- Improved toughness
- Better wear resistance
- More consistent hardness
- Greater manufacturing precision
- Better edge stability
Although both steels benefit from this production method, their chemical compositions give them distinctly different performance characteristics.

What Determines Knife Performance?
Many knife buyers assume that hardness alone determines quality.
In reality, a knife’s performance depends on balancing several important characteristics.
Understanding these properties makes comparing steels much easier.
Check Our Guide CPM CruWear Steel Review
Hardness
Hardness measures a steel’s resistance to permanent deformation.
Knife hardness is usually measured using the Rockwell Hardness Scale (HRC).
Higher hardness generally provides:
- Better edge retention
- Higher wear resistance
- Longer cutting performance
However, excessive hardness without sufficient toughness can increase the risk of chipping.
The best-performing steels balance hardness with durability.
Toughness
Toughness measures how well steel resists cracking, chipping, or breaking under stress.
A tough blade tolerates:
- Twisting
- Impacts
- Heavy carving
- Batoning
- Lateral pressure
Outdoor knives and heavy-duty utility knives often prioritize toughness over maximum hardness.
Wear Resistance
Wear resistance describes how slowly the cutting edge loses material during repeated use.
Steels with high wear resistance remain sharp longer when cutting abrasive materials.
These include:
- Cardboard
- Rope
- Leather
- Wood
- Plastic
- Fiber-based materials
Higher wear resistance usually means less frequent sharpening.
Corrosion Resistance
Corrosion resistance determines how effectively steel resists:
- Rust
- Staining
- Pitting
- Moisture
- Food acids
This characteristic becomes especially important in:
- Kitchens
- Coastal environments
- Humid climates
- Fishing
- Everyday pocket carry
Ease of Sharpening
Every knife eventually requires sharpening.
Some steels sharpen quickly using conventional stones, while others require harder abrasives because of their high wear resistance.
Generally speaking:
- Higher wear resistance means more sharpening effort.
- Lower wear resistance usually means easier maintenance.
Finding the right balance depends on how often you’re willing to sharpen your knife.
Chemical Composition Comparison
Knife steel performance begins with chemistry.
Each alloying element contributes specific properties that influence how the finished blade behaves.
The following table summarizes the primary differences.
| Element | M390 | CruWear |
|---|---|---|
| Carbon | High | High |
| Chromium | Very High | Moderate |
| Vanadium | High | Moderate |
| Molybdenum | High | Moderate |
| Tungsten | Low | Moderate |
| Niobium | Small | Small |
Rather than memorizing exact percentages, it’s more useful to understand what each alloying element contributes.
Carbon: The Foundation of Blade Performance
Carbon is the most important alloying element in knife steel.
Without sufficient carbon, steel cannot achieve the hardness required for a long-lasting cutting edge.
Carbon contributes to:
- Hardness
- Edge retention
- Wear resistance
- Carbide formation
Both M390 and CruWear contain enough carbon to achieve premium cutting performance.
However, carbon alone does not determine how the knife behaves.
Its interaction with other alloying elements plays an equally important role.
Chromium: Stainless Protection
Chromium is responsible for corrosion resistance.
When enough chromium remains available within the steel matrix, it forms an invisible oxide layer that protects the blade from oxidation.
This protective layer dramatically reduces:
- Rust formation
- Surface staining
- Pitting
M390 contains a very high chromium content, allowing it to provide excellent corrosion resistance under normal use.
CruWear contains considerably less chromium, meaning it offers moderate corrosion resistance rather than true stainless-level protection.
With proper maintenance, CruWear performs well, but it requires more attention after exposure to moisture.
Vanadium: The Secret Behind Edge Retention
Vanadium is one of the most valuable alloying elements found in premium knife steels.
Its benefits include:
- Extremely hard carbides
- Improved wear resistance
- Better edge stability
- Grain refinement
- Enhanced cutting performance
M390 contains a relatively high amount of vanadium, contributing to its outstanding wear resistance.
CruWear also benefits from vanadium carbides, although its alloy balance emphasizes toughness alongside wear resistance rather than maximizing abrasion resistance alone.
Molybdenum and Tungsten
These alloying elements improve strength and overall blade performance.
Molybdenum contributes to:
- Better hardenability
- Increased wear resistance
- Improved strength
- Better high-temperature stability
Tungsten contributes to:
- Enhanced edge stability
- Increased abrasion resistance
- Greater cutting endurance
Although present in different amounts, these elements help both steels achieve premium performance in demanding cutting applications.
Why Steel Chemistry Matters
No single alloying element determines knife performance.
Instead, every property results from the interaction between:
- Carbon
- Chromium
- Vanadium
- Molybdenum
- Tungsten
- Niobium
- Heat treatment
- Powder metallurgy microstructure
This balance explains why M390 and CruWear can both be considered premium steels while excelling in different areas.
M390 prioritizes corrosion resistance and wear resistance, making it highly versatile for everyday use. CruWear, meanwhile, emphasizes toughness without sacrificing strong edge retention, making it especially attractive for users who subject their knives to demanding cutting tasks.
Edge Retention
Edge retention is one of the most important factors when evaluating a knife steel. It determines how long a blade remains sharp before it needs to be resharpened. A knife with excellent edge retention can complete more cutting tasks with consistent performance, reducing maintenance and downtime.
Both M390 and CruWear are considered premium steels with impressive edge retention, but they achieve it in different ways.
M390 relies heavily on its high wear resistance and dense concentration of hard carbides, while CruWear combines a balanced carbide structure with exceptional toughness, allowing the edge to remain stable even under demanding use.
Let’s take a closer look at each steel.
M390 Edge Retention
M390 has earned a reputation for outstanding edge retention.
Its combination of high carbon, chromium, vanadium, and molybdenum creates a fine carbide structure that resists wear exceptionally well. Thanks to the powder metallurgy process, these carbides are distributed evenly throughout the steel, helping the blade maintain a sharp edge for extended periods.
During everyday use, M390 performs exceptionally well when cutting:
- Cardboard
- Paper
- Rope
- Plastic packaging
- Leather
- Food
Instead of becoming dull quickly, the edge gradually loses aggressiveness while remaining highly functional.
For most users, sharpening sessions are relatively infrequent compared to many conventional knife steels.
CruWear Edge Retention
CruWear also delivers excellent edge retention, although its design philosophy differs slightly.
Rather than maximizing wear resistance above everything else, CruWear seeks to balance edge retention with toughness.
The result is a blade that not only stays sharp for a long time but also resists micro-chipping during demanding work.
This makes CruWear particularly effective for:
- Wood carving
- Bushcraft
- Utility work
- Workshop tasks
- Outdoor use
Under heavy cutting conditions, many users appreciate how consistently CruWear maintains a usable working edge.
Which Steel Holds an Edge Longer?
Under controlled cutting tests involving abrasive materials, M390 generally has a slight advantage in pure edge retention.
Its higher wear resistance allows the cutting edge to lose material more slowly over time.
However, the difference is often smaller than many people expect.
During normal everyday cutting, both steels remain sharp long enough that most users are unlikely to notice a dramatic difference.
Winner: M390 (slight advantage)
Wear Resistance
Wear resistance measures how effectively steel resists abrasion during repeated cutting.
Although closely related to edge retention, it specifically refers to the blade’s resistance to losing material through friction.
Several factors contribute to wear resistance:
- Carbide volume
- Carbide hardness
- Carbide distribution
- Heat treatment
- Overall steel chemistry
M390 Wear Resistance
Wear resistance is one of M390’s greatest strengths.
Its high concentration of chromium and vanadium carbides creates an extremely durable cutting edge capable of handling abrasive materials for long periods.
Users who regularly cut:
- Thick cardboard
- Fiberglass-reinforced materials
- Rope
- Plastic strapping
- Carpet
often appreciate how slowly the edge wears.
This makes M390 an excellent choice for users who prefer less frequent sharpening.
CruWear Wear Resistance
CruWear also provides excellent wear resistance, although it intentionally sacrifices a small amount of abrasion resistance to improve toughness.
Its carbide structure remains highly effective for demanding cutting applications.
In practical use, CruWear easily handles:
- Hardwood
- Leather
- Cardboard
- Rope
- Utility cutting
without excessive edge wear.
For most users, the difference between these two steels is relatively small outside prolonged industrial cutting.
