Maximum safety (SECUMAX)
Concealed blade: The blade is not open, rather concealed, shielded from both people and goods alike. Giving you a maximum degree of safety from cut injuries whilst cleverly protecting your goods.
Very high safety (SECUPRO)
Fully automatic blade retraction: The "intelligent" cutting tool: as soon as the blade leaves the cutting material, it withdraws automatically into the handle. Even when you keep on pressing the slider or the handle.
High safety (SECUNORM)
Automatic blade retraction: Thumbs up for a high degree of safety. As soon as you start cutting, let go of the slider. The blade will disappear into the handle the moment it loses contact with the material being cut.
"Manual blade retraction: The blade is permanently accessible. However, you can retract it manually into the handle when laying the knife down and transport it safely."
Safer blade change (with magnet)
The integrated magnet prevents the blade from falling out when you open the blade cover.
Blade change with tool
Depending on the knife its best to use the fitting screwdriver or -key.
Tool-less blade change
Easy by hand blade change, no further tools needed.
Blade change not possible. In case the blade gets blunt the whole knife will be exchanged.
