Inside the Innovative OLFA SK-16 Safety Knife

Depending on the industry you’re in and the daily tasks to be performed, the knife you use can make a huge difference. That’s why safety knives have become an essential element of occupational safety, helping prevent injuries in the workplace and enabling employees to perform their cutting work efficiently and safely. Whenever there’s a hand tool involved, it’s important to ensure that everyone is able to carry out their roles with as little risk as possible.

That’s when OLFA Safety Knives come in handy, offering a secure grip and recessed blades on many styles to reduce the risk of injury while providing the best cutting experience. And it’s with safety in mind that OLFA has carefully manufactured and released a knife that embodies safety and performance into one: the OLFA SK-16 Quick-Change Concealed Blade Safety Knife. What makes this knife so special? Let’s find out.

Cutting Made Easier

Similar to other OLFA safety tools, the OLFA SK-16 Safety Knife comes with a concealed blade that ensures your hands won’t get hurt whether you’re using or carrying the knife around. But unlike other knives on the market featuring complicated cutting mechanisms, the OLFA SK-16 Safety Knife makes cutting a one-step process. You truly don’t have to do anything as the blade requires no activation: simply pull through materials to start cutting. 

But OLFA wouldn’t be who they are if they hadn’t pushed the blade technology even further. How? By creating an efficient quick-change blade release system. All you have to do is pull back on the red button to release and remove the used blade, then insert the new one and click it into place. The replaceable blade head also reduces waste compared to disposable models.

Sharp, but Safe

Have you ever heard of the term force exposure? First applied in a study on the prolonged use of a computer mouse, this phenomenon has been used to explain why a sharp blade is safer than a dull one. When you’re cutting with a sharp blade, you won’t have to use as much downward force to cut the material. This will in turn decrease the chances that the knife slips out of your hands, or that you injure yourself in the process of applying added pressure. That’s why the OLFA SK-16 Safety Knife comes preloaded with a premium stainless-steel blade that can cut 7x more* than competitive blades.

Not Your Average Knife

Although safety knives are mostly common among workers in delivery, logistics department, warehouses and stores, the OLFA SK-16 Knife features an adapted design that makes this tool ideal to cut through a variety of applications. With a curved ergonomic fiberglass-reinforced handle and a metal tape splitter, this heavy-duty safety knife can cut many tough materials while still protecting the goods under the cutting surface. This is made possible by a 6.5mm open channel design that minimizes resistance and allows for a larger surface to be sliced.

The OLFA SK-16 Safety Knife can be used with:

- Up to 2-ply corrugate - Bagged Goods
- Cable ties - Films
- Flooring Protection - Plastic Strapping Bands
- Stretch Film - Carpet
- Rubber Sheeting  - Tape

No matter the safety knife you choose, it’s important that you evaluate what you’re looking for in the tool itself. Ask yourself, what makes it safer: is it the handle design? Is it where the blade is placed? That’s why OLFA is proud to have manufactured a knife that embodies tremendous design needed to create the optimal user experience.

Pro Tool Reviews couldn’t have said it better: “Whether it’s workplace policy or personal choice, the exposed blade of a utility knife isn’t always the best choice. OLFA’s ingenious safety knife design comes to the rescue for a wide range of cutting tasks”.
