Four-knife set for daily cutting tasks

This DIYSELF utility knife set supplies four retractable cutters and ten replacement blades for home, workshop or craft use. The aluminum bodies are coloured red, black, yellow and blue for quick identification. Each knife uses a screw-secured blade that is changed with a screwdriver for safety. The pack suits general-purpose cutting across cardboard, paper, plastic, foam, carpet and leather.

Screw-lock blade retention

Blades are held by a single screw rather than a slide latch, so a screwdriver is required to release and fit a fresh edge. The mechanism prevents accidental blade exposure during transport or heavy pressure. Ten SK5 high-carbon steel blades are included, giving multiple changes before a separate purchase is needed. The design favours deliberate blade swaps over speed.

Aluminium frame with SK5 steel edges

The 0.458 kg total weight reflects solid aluminium handles that resist flex when scoring dense materials such as carpet or leather. SK5 blades keep a keen edge through repeated cardboard and foam cuts without rapid dulling. The metal construction dissipates hand heat during long sessions and withstands drops onto hard floors. Sustained cutting feels consistent because the handle does not deform under grip pressure.

Questions about this item

What does the 10-blade supply mean for day-to-day use?

The set includes ten SK5 steel blades that can be swapped into any of the four knives, giving a long run of fresh edges before you need to buy replacements.

How does the screw-secured blade design affect blade changes?

Each blade is held by a screw, so you need a screwdriver to release the old one and fit a new blade, which prevents accidental release during cutting.

What do the aluminium bodies and 5 cm size imply for storage?

The four knives have aluminium bodies and measure about 5 cm, so they fit easily in a toolbox, drawer or pocket without taking up much space.
