MagnaMax Knife Steel for Makers
May 26th 2026
Why MagnaMax™ Knife Steel Is the Next Evolution for Makers
MagnaMax™ knife steel builds on the success of MagnaCut® by delivering significantly higher edge retention while maintaining excellent corrosion resistance and strong toughness. For knife users who want longer cutting performance, MagnaMax™ was designed specifically for that purpose.
For years, knife enthusiasts searched for a stainless steel that balanced toughness, corrosion resistance, and wear resistance without major compromises. Dr. Larrin Thomas helped change that conversation with MagnaCut®. Now, MagnaMax™ pushes the MagnaCut® family even further for users focused on maximum edge retention. Larrin explains how MagnaMax™ evolved, why buyers demanded it, and what makes it different from previous high wear resistance steels.
How MagnaCut® Changed the Knife Industry
MagnaCut® changed the knife industry because it introduced a new balance of toughness, corrosion resistance, and edge retention in a stainless steel. According to Larrin Thomas, the response exceeded even his expectations.
Knife makers, YouTube reviewers, and knife buyers quickly embraced MagnaCut®. Many users viewed it as the “new hot steel” because it solved a long-standing problem in the knife world. Traditionally, stainless steels sacrificed toughness and cutting performance compared to non-stainless steels. MagnaCut® changed that balance.
Larrin explained that MagnaCut® used a new alloy concept with reduced chromium and carefully balanced vanadium and niobium carbides. As a result, the steel achieved properties similar to premium non-stainless powder metallurgy steels while maintaining outstanding corrosion resistance.
That breakthrough helped MagnaCut® become one of the most talked-about knife steels in the industry. It also created the foundation for a larger family of steels.
Why MagnaMax™ Was Developed
MagnaMax™ was not an afterthought. Larrin Thomas originally presented the idea for a family of steels when discussing MagnaCut® with Niagara Specialty Metals and Crucible years ago.
At the time, MagnaCut® filled a major gap in the market because no stainless steel combined high toughness with strong wear resistance. However, Larrin already understood that many knife buyers would eventually want even more edge retention.
That higher wear resistance version eventually became MagnaMax™.
The goal was clear from the beginning. MagnaMax™ would target users who prioritize cutting performance and long edge life over maximum toughness. Folding knife users and EDC enthusiasts especially pushed demand in that direction.
According to Larrin, many companies and knife buyers wanted a stainless steel with edge retention closer to steels like K390 or CPM® 10V while still maintaining MagnaCut®-level corrosion resistance.
MagnaMax™ vs MagnaCut® - What Changes?
MagnaMax™ increases edge retention by roughly 40% compared to MagnaCut®. That improvement comes from significantly higher wear resistance.
Larrin explained that MagnaCut® scores around 500 in CATRA edge retention testing, while MagnaMax™ reaches roughly 700 to 750. To achieve that increase, the alloy doubles the vanadium content compared to MagnaCut®.
Higher vanadium creates more hard vanadium carbides, which improve wear resistance and help the edge last longer during abrasive cutting tasks like cardboard or rope cutting.
However, every knife steel involves tradeoffs. As wear resistance increases, toughness naturally decreases. MagnaMax™ accepts some reduction in toughness to achieve its major increase in edge retention.
Still, MagnaMax™ maintains a strong balance of properties. Larrin noted that MagnaMax™ has toughness similar to steels like S35VN or CPM 154 while delivering much greater edge retention. Those steels were amongst the toughest powder metallurgy steels prior to MagnaCut®. It also maintains the excellent corrosion resistance that made MagnaCut® famous.
That combination gives MagnaMax™ a unique position in the knife steel market.
Why Folding Knives Benefit Most From MagnaMax™
MagnaMax™ is especially well suited for folding knives and EDC applications because those users often prioritize edge retention over maximum toughness.
Many folding knife users cut abrasive materials throughout the day and want a blade that stays sharp longer between sharpening sessions. MagnaMax™ addresses that need directly.
Larrin explained that smaller blades also reduce manufacturing challenges tied to high wear resistance steels. Grinding a small folding knife blade creates less wear on equipment than grinding large fixed blades or chopping knives.
At the same time, MagnaMax™ still provides better toughness than older high wear resistance stainless steels like M390 or 20CV. That improved balance allows makers to use thinner, more acute edge geometry without sacrificing as much durability.
Kitchen knife makers may also benefit from MagnaMax™ because many kitchen users value long cutting performance and excellent corrosion resistance.

Why Niagara Specialty Metals Was Critical
Niagara Specialty Metals played a major role in helping MagnaCut® and MagnaMax™ become reality.
Larrin explained that when he first presented MagnaCut®, some uncertainty existed about whether the product should move forward. However, Bob Shabala immediately believed in the concept and pushed to make it happen.
That support became even more important after Crucible shut down during bankruptcy proceedings.
According to Larrin, Niagara Specialty Metals helped keep knife steel production moving by building new relationships with suppliers like Erasteel and Carpenter Technology Corporation.
Niagara also provides specialized rolling expertise that many knife makers rely on. Producing thin, flat, high alloy knife steel requires specialized equipment and experience that few companies possess.
Larrin described Niagara as “the key to everything” because of their technical expertise, knife industry knowledge, and commitment to supporting knife manufacturers.
What Knife Makers Should Know About MagnaMax™
Knife makers can achieve even better results with MagnaMax™ by collaborating closely on heat treatment and geometry optimization.
Larrin explained that many companies simply send steel to heat treaters without exploring how different processing variables affect final performance. However, adjusting temperatures, equipment, and heat treatment parameters can significantly improve results for specific applications.
He emphasized that Niagara Specialty Metals are available to help knife companies optimize their products. That collaborative approach can help makers maximize edge retention, toughness, and cutting performance based on their exact knife design and intended use.
Conclusion
MagnaMax™ knife steel expands the MagnaCut® family by delivering dramatically higher edge retention while maintaining excellent corrosion resistance and strong toughness. Instead of replacing MagnaCut®, it gives knife makers and buyers another option tailored for different priorities.
For folding knives, EDC blades, and users who want long cutting performance, MagnaMax™ offers one of the most advanced balances currently available in stainless knife steel. Combined with Niagara Specialty Metals’ manufacturing expertise and ongoing collaboration with Larrin Thomas, MagnaMax™ represents another major step forward in modern knife steel design.
