Where to Buy

Easier to Pull. Safer to Cut.

Accidents happen, but the new OLFA SK-15 Disposable Concealed Blade Safety Knife helps reduce the chance of laceration injuries on the job.

This compact, durable knife begins with an ultra-sharp stainless steel blade in a protected blade channel for ultimate user safety. The stainless steel blade requires 25% less pulling force per cut equaling longer blade life while reducing user fatigue. Additionally, workers never touch a blade – when the Disposable Concealed Blade Safety Knife’s blade gets dull, simply throw it away and replace with a new one. No blade changes ever required.

The durable plastic handle has blunt plastic piercing tips on each blade end. These tips grab into materials to initiate cutting while also encasing the blade ends. The SK-15 Disposable Concealed Blade Safety Knife features unique flow-through cutting channels that reduce friction to allow for easy cutting of materials up to 4mm thick (0.16”). The dual-sided blades extend the life of this Level 3 Safety Knife for twice the work of single-blade competitors.

The handle has a wedge-shaped nose that acts as a splitter for puncturing and opening packing tape. The oversized loop at the end of the handle allows the tool to be hung from a hook or tethered to a lanyard for safety. When you need to protect your workers with an enclosed cutting solution, reach for the new OLFA SK-15 Disposable Concealed Blade Safety Knife.
