American Cutting Edge Acquires Industrial Blade Division from Superion

American Cutting Edge, a division of CB Manufacturing & Sales Co., Inc., is pleased to announce the acquisition of the industrial blade product line from Superion, Inc., of Xenia, Ohio.  The purchase includes both the assets used to manufacture blades as well as the intellectual property surrounding the product line.

American Cutting Edge is the leader in the design, manufacturing, and distribution of steel and tungsten carbide industrial blades worldwide.  Superion has been one of the foremost manufacturers of Solid Tungsten Carbide and Ceramic Razor Blades, premium and long-lasting blades used to cut or convert materials such as foil, film, paper, textiles, and other resistant materials, as well as the innovator of the proprietary resharpening process that allows multiple reuses of their blades.

This purchase will allow Superion, Inc. to concentrate on their primary line, which is the manufacture and sell of precision cutting tools for metalworking.  The addition of the Solid Tungsten Carbide and Ceramic Industrial Blades to the American Cutting Edge brand will allow American Cutting Edge to continue to offer their customers the newest and best technology for their material converting needs.

Chuck Biehn, president of American Cutting Edge is positive about the acquisition:  “There is a long history of partnership and synergy between our two companies and we are excited that we have come to an agreement that will allow both companies to do what we love and do the best.  Superion will be able to focus all their skills and talents on providing precision metal cutting tools internationally and American Cutting Edge will expand our global product offering with advanced technology that will benefit our customers with extended blade life and reduced overall costs.”

The purchase was finalized June 27, 2014.

American Cutting Edge’s parent company, CB Manufacturing & Sales Co., Inc. is owned by the Biehn Family and provides industrial machine knives and razor blades worldwide, as well as contract surface and EDM services throughout the Midwest.  They also own Certified Heat Treating Incorporated, whose West Carrollton and Springfield facilities provide metal processing services to customers in a five state region.  CB Manufacturing & Sales was established in 1965 by Charlie Biehn Sr., and will proudly celebrate 50 years of business in 2015.

Announcement - Name Change


Announcement – Name Change

In 2015, CB Manufacturing will celebrate our Fiftieth year as one of the U.S.’s premier knife manufacturing companies.  We may be marking our golden anniversary, but we continue to live our mission statement: Better * Faster * Leaner * Stronger.  In that spirit, on July 1, 2014, we are proud to introduce to you our new name: American Cutting Edge, a division of CB Manufacturing.  We have chosen to adopt as our new name the title of the razor blade focused branch of our company because it reflects overall what our company is: North America’s number one provider of cutting edges.

Many of our valued customers currently purchase from both CB Manufacturing and American Cutting Edge and the combining of our two divisions—machine knives and razor blades—will eliminate the need to issue two separate purchase orders and maintain two separate accounts when placing orders.  It will also simplify the quoting and ordering process for our customers, as they will have a single service expert who oversees all their orders from start to finish.

Regardless of our name, American Cutting Edge, a division of CB Manufacturing, will continue to focus on the same principles that are allowing us to commemorate fifty successful years: exceptional customer service and the highest standards of quality.  The same principles that Charlie Biehn set in place back in 1965.

During the changeover on July 1, 2014, and afterwards, we will always accept purchase orders issued to either CB Manufacturing or American Cutting Edge as our customers update their systems to reflect our new name.

Please join us in marking our Fiftieth birthday.  And we’d like to thank you, our loyal and valued customers.  Over the past five decades, we have all weathered changes in the economy and technology and emerged stronger and better than ever.  We look forward to celebrating another fifty years in partnership with the customers who are so instrumental to our success.

Cryogenic Treatment

CB Manufacturing and Certified Heat Treating, Inc. offer Deep Cryogenic Treatment of knives, blades, and other industrial tools, in our in house microprocessor controlled, cryogenic chamber.

During heat treating, steel’s micro-structure transforms from austenite to martensite, which makes the steel much more wear resistant. However, some small pockets of austenite may not transform and this does not allow the knives to perform as well as they can. Deep Cryogenic processing helps change retained austenite to martensite, completing the transformation process.

Our Deep Cryogenic processing is different from conventional cryogenic processing and requires cooling the parts to more than 300° below zero compared to about 120° for conventional cryogenic processing. This process includes cooling the parts at a programmed rate, soaking the parts for up to thirty-six hours, and then an additional tempering operation to relieve any stress that may remain. We combine Deep Cryogenic processing with our state of the art Vacuum Heat Treating capability to offer unmatched metal treating and the best performance possible from your knives and tools.

Dayton Manufacturer Makes Acquisition

A local industrial knife maker has purchased the product line of another Dayton-area manufacturer.
American Cutting Edge in Centerville acquired the industrial blade business of Xenia-based Superion Inc. The sale includes Superion’s line of solid tungsten carbide and ceramic razor blades —premium, long-lasting blades used to cut or convert materials such as foil, film, paper and textiles —as well as its proprietary sharpening process that allows the blades to be used multiple times.
Terms of the deal, which includes equipment and intellectual property, were not disclosed. Company officials say the sale will allow Superion Inc. to concentrate on its primary line, the manufacturing of precision cutting tools for metalworking.
American Cutting Edge — a division of West Carrollton-based CB Manufacturing & Sales Co. — designs and produces steel and tungsten carbide industrial blades that are sold globally.
Chuck Biehn, CEO of CB Manufacturing, told me Monday morning the acquisition is a big deal because his company had been importing a majority of the products it just acquired from Superion.
“This allows us to react faster to customer needs and have the ability to offer more American-made products,” Biehn said. “We believe with this new equipment we will be able to compete with the factories overseas where we now get the product.”
American Cutting Edge will pick up two employees from Superion and will need to hire at least two more people. Biehn hopes to eventually expand the newly acquired product line.
CB Manufacturing has about 140 employees, which includes its American Cutting Edge and Certified Heat Treating divisions. The parent company is one of the Top 100 local companies with more than $24 million in revenue last year, according to Dayton Business Journal research.
This is the second acquisition of a local company for CB Manufacturing in less than a year. Last fall, it purchased Heat Treating Inc. in Springfield.

Blade Longevity

Customers often ask what they can do to increase the life of their machine knives and razor blades. While there isn’t a set in stone blanket answer for this question there are a few tips we can offer. It is important to note that not all ideas are appropriate to all applications. Many aspects go into a finished product such as knife material, coatings, environment, cutting substrate, geometry and surface finish of the blade, and the list goes on. If you are interested in getting better blade life, please read through the information below and contact one of our knife experts to discuss your options. 


One of the factors for blade longevity is the material in which it is made.  Your application and desired price point will likely dictate the best material for you.  Depending on what you are cutting you may need harder steel, or something with higher carbon content. In many cases there are different options for what material you can use. One material may get the job done for an acceptable period of time; however another material may work even better for an extended time frame.  For example CB Manufacturing has recently released a new product, our carbide inlaid densifer knife. This blade, with its carbide inlay could double in life from its non-carbide inlaid counterpart, and should give the user cleaner cuts.  There are many materials available that can be considered for each knife. Carbon Steel, Stainless Steels, High Speed Steels and Tool Steels are all options to discuss with your blade expert. Click here for more information about blade and knife materials.


In conjunction with the material of your knife you may be able to choose a coating that will make your blade last even longer. There are a slew of coatings available including Titanium Nitride, Boron Carbide, and Teflon just to name a few.  Each coating has a different use, for example Teflon is generally used to increase the lubricity of the blade surface and can be great for adhesive cutting applications while a Boron Carbide, more commonly known as ceramic coating, is generally used to add extensive wear life to razor blades, making the blade last 20+ times longer. Contact your Product Manager to discuss what options would be best for you and your application. For more information on coatings and how they interact with different steels you can also visit our website.

Hardness Vs Toughness

Another aspect of blade life is the hardness verses the toughness of the blade. Generally as hardness increases, toughness decreases. Toughness is desirable when blades are heavily impacted, hardness when a blade is exposed or abrasive materials. Hardness is a characteristic of a solid material expressing its resistance to permanent deformation. The Rockwell or Vickers hardness scales are most commonly used in the industrial blade industry. Toughness on the other hand is the maximum amount of energy a material can absorb before fracturing, which is different than the amount of force that can be applied. The key with industrial knives is finding that magical blend of hardness and toughness that will give a blade long life and good durability to stresses and impacts depending on the application. If you would like more information about this concept or would like to discuss your blades hardness or toughness please contact our knowledgeable blade staff.
