It is important to know

When purchasing replacement blades for your upholstery knife, the main focus is on compatibility with your existing tool and on controlling replacement when the sharpness wears off. It is easy to overlook the actual need for sharpness and whether the supply of blades matches the frequency of use in the business environment. When making your selection, pay particular attention to the logistical consequences of insufficient stock or the wrong size of blades.

• A stock of replacement blades helps keep your work flowing, so consider purchasing multiple sets if the tool is in regular use.
• When choosing, pay attention to the width (18 mm) and shape of the blade and check compatibility with your upholstery knife, as not all blades are universal.
• Replacing worn blades significantly improves the accuracy and quality of the cut, especially when cutting cardboard or plastic wrap, where a dull blade quickly affects the result.
• Remember that blades are consumables that directly affect work safety and efficiency – planning for timely replacement reduces the risk of poor cuts or injuries.

Answers to frequently asked questions

Are these blades suitable for all 18 mm wide upholstery knives?

The blades are designed for standard upholstery knives with 18 mm wide blades, but it is recommended to check compatibility with the exact model of your knife before purchasing.

How long do individual blades last with regular use?

The durability of a single blade depends on the intensity and type of materials you cut; for daily use in an office or warehouse, we recommend regular replacement when you notice a decline in cutting accuracy.

Can the blades be broken down to a shorter length?

Most 18mm blades have breakable segments, making it easier to sharpen the blade on the fly, but check if this kit allows this before using.

Is the 10-blade pack suitable for larger offices or warehouses?

The package is sufficient for medium-duty environments, but in very intensive work processes it makes sense to consider a larger supply.
