Why OLFA Safety Knives?

Because of the different materials being handled and the many departments involved, “Safety First” is one of the most important rules implemented at warehouses, packaging, and manufacturing facilities. Whether cutting through tape on a package, corrugated boxes, shrink wrap, bagged goods, film or layers of paper or foil, a high-quality knife will reduce your risk of accidents while helping you work with ease. 

And this is exactly what OLFA’s safety knives stand for, each tool carefully designed to be Sharp, Safe, and Simple

OLFA Safety Lineup of Knives  


Blades you can count on.  

Blunt or dull knives are the thief of joy for many applications, since a dull blade requires more pressure to cut and increases the chances of the knife slipping. Born in the region where Samurai once roamed, OLFA blades are made of the finest Japanese steel to exacting specifications. These premium blades have an exceptional razor-sharp edge to cut through almost anything. 

And this applies to OLFA safety knives (and blades) as well. These blades are devised to be safe while extra sharp. Many of the safety knives come preloaded with an exclusive dual-edge safety blade that offers sharpness and reduces damages to contents. Other safety knives feature a blade with a rounded tip to reduce risk of contamination from broken tips. But regardless of the blade type, all OLFA blades deliver unmatched cutting power– some offering more than you could ever imagine in a safety knife. 

The OLFA SK-15 Disposable Concealed Blade Safety Knife features an ultra-sharp stainless-steel blade that results in 25% LESS pulling force per cut.

The OLFA SK-16 Quick-Change Concealed Blade Safety Knife comes with a premium stainless-steel blade that cuts over 7x more* than competitive blades.



Boost performance while maximizing safety.

Have you ever injured yourself while handling a sharp object? Unfortunately, you’re not alone! Many people are injured by cutting tools on a regular basis. So, having a durable set of safety knives you can rely on is essential to preventing injuries. 

To minimize the risk of injury to users and materials, our knives are designed with safety as the top priority. Everything from the retracting mechanisms of the blades to the function itself, has an emphasis on this principle. With that in mind, OLFA has developed three families of safety knives that allow professionals to be safe when using these tools in a variety of functions.  


OLFA Semi-Automatic Safety Knives

The Semi-Automatic Safety Knives feature spring-activated blades that self-retract as soon as the blade loses contact with the cutting surface, as long as the slide is disengaged. Workers don't have to remember to “close the blade” after each use, which in turn helps prevent injuries that would be caused by reaching for a knife and touching an open blade.

OLFA Fully-Automatic Safety Knives

If you need to take safety a step further, the Fully-Automatic Safety Knives are what you’re looking for. Not only does the blade automatically retract as soon as lifted from the cutting surface, but this safety feature cannot be overridden– even if the blade slide is still engaged. Thanks to this enhanced safety mechanism, even the most distracted workers will be safe.

    OLFA Concealed Blade Safety Knives

    Lastly, the Concealed Blade Safety Knives offer a recessed blade that’s concealed within an open cutting channel. What makes this last set of knives unique is that they allow the blade to always be active, while still protecting the users from blade exposure– by shielding the blade in the channel. This means that these knives will only meet the materials intended to be cut, ensuring both your hands and the contents are safe.

      Simple, yet effective.  

      Any cutting tool is only worth carrying around in your tool belt or pocket if it does the job. This is why having an easy-to-use knife that doesn’t make you sacrifice functionality or efficiency is the way to go. Our tools are ergonomic and easy to use for a variety of applications. Workers are able to complete tasks more quickly and comfortably, without the fear of injuring themselves or damaging any materials. 

      The simplicity and effectiveness of an OLFA safety knife can be seen in many different ways. From being able to simply flip the blade for right- or left-handed use, to easily carrying around your safety knife thanks to a lanyard hole, to never needing extra tools to change your blades. These features are just some of what makes our knives the top choice for professionals everywhere.
