Ronsta Knives Manual Retractable Knife With Screw Lock 18mm

This is a manually operated retractable knife designed for controlled blade extension and secure locking during use. It features an 18mm snap-off blade system that allows users to break off worn sections to expose a fresh cutting edge. The knife includes a screw lock mechanism that holds the blade firmly in place to prevent unintended movement. Its construction focuses on reliability for repetitive cutting applications where consistency matters.

It protects against blade creep or accidental retraction during pressure-intensive tasks, which could compromise cut quality or pose a safety risk. The locking system ensures the blade remains fixed at the desired length, reducing the chance of slippage when cutting resistant materials. This makes it suitable for jobs requiring steady, accurate cuts over extended periods.

It is commonly used in environments where materials like film, leather, cardboard and plastic need to be trimmed or shaped. The tapered tail and curved handle improve handling and reduce hand fatigue during prolonged use. The metal guide and stability nose add rigidity to the blade housing, supporting consistent performance. Replacement blades are available separately under the designation KB005-10.
