It is important to know

When choosing replacement blades for your upholstery knife, it is crucial to understand whether the dimensions and type of blade are compatible with your existing tool and whether the product, in terms of the number and type of blades, meets the planned scope of use. It is recommended to pay special attention to the issue of compatibility with your knife and the realistic need for a supply of blades, as needs can quickly vary in different business environments.

• Replacement blades are consumables, so if you use them frequently or intensively, you should expect to replace them regularly - a pack of ten can reduce interruptions.
• The 9 mm blade width only fits certain types of knives; check for exact match before purchasing, as incorrect selection reduces the product's usability.
• Restoring the sharpness of a knife by changing the blade significantly improves accuracy, reduces cutting effort, and contributes to greater efficiency in the office or warehouse.
• Replacement blades do not have a handle or guard; they are used solely as a component in an existing knife and cannot be used independently.

In practice

🟢 Cutting paper and lighter office materials

Very suitable – 9 mm blades are typically intended for precise cutting of paper, foil and thin materials in everyday office tasks.

🟢 Replacing worn blades to maintain cutting accuracy

Very convenient – the package allows for easy and quick replacement of dull blades, which is essential for maintaining the quality of the cut during intensive use.

🟡 Cutting thicker materials (cardboard, harder plastic)

Suitable with limitations – narrow blades are useful for thinner cardboard or plastic, but harder or thicker materials require greater care or perhaps the selection of a wider blade.

🔴 Use without a suitable upholstery knife

Less convenient – the blades have no handle and cannot be used safely or effectively without a compatible knife.
