Overview & First Impressions
A record press runs hot, fast and loud, and the operator spends the shift trimming the flash that squeezes out of the mould. That trim is soft PVC with a hard edge, and it dulls a blade in a way cardboard never does. The knife also opens boxes of labels and sleeves, cuts splice tape and frees a stuck puck. The Tenable Rango B1120A3 in stonewashed 14C28N handles the repetition without complaining.
Materials & Construction
14C28N is a sensible choice for a plant floor. It resists staining, sharpens on a simple stone and takes a toothy edge that bites into PVC instead of skating across it. Tenable knives leaves the finish stonewashed, which hides the scuffs that come from a steel bench and stops the blade reflecting the press lights into the operator's eyes, a small detail that matters more than it sounds on a night shift.
Design & Details
The Rango is a liner lock with an aluminium handle, a deep carry clip and a blade profile that keeps a straight section for trimming and a fine tip for poking. The handle is smooth enough to wipe clean of PVC dust without a brush, and the action is quick because the knife gets opened and closed dozens of times an hour. There is no texture to trap swarf, which is deliberate.
Real-World Use
In the plant the knife trims flash from a fresh pressing, cuts the paper sleeve that wraps a test pressing and opens cartons of inner sleeves. It also cuts the tape that holds a stack of jackets and slices the plastic strapping on a pallet. Among EDC knives chosen by people who work with their hands on a production line, the Rango is popular because it stays comfortable through a full shift of small cuts.
Ownership Notes
PVC dust is abrasive, so rinse the blade at the end of every shift rather than every week, and blow the pivot out with compressed air. A few strokes on a fine diamond rod restores the edge faster than a stone because 14C28N responds well to light touch-ups. Keep the clip screws snug. EdcMall stocks the Rango in several blade finishes, and the stonewashed version is the most practical for a plant.
Who Is This For?
Buy it if you cut flexible plastic, rubber or heavy paper all day and want a knife that stays comfortable and sharp without fuss. It suits the press operator, the warehouse picker and the print finisher. Skip it if your work is woodcarving or food, where a different grind and a different steel will serve you better.
Final Verdict
The Rango B1120A3 is a production-line knife done right: thin enough to trim cleanly, tough enough to survive a factory, and cheap enough that you will actually use it. 14C28N is the quiet hero here, because it lets an operator refresh an edge in the middle of a run instead of waiting for maintenance.
