Firefighters use the minicutters for cutting through car pedals and steering wheels, so they have to deliver a powerful cutting force. At the same time, they can be operated with one hand in a tight space. Cutting through pedals in a crashed car for example is often a job that has to be carried out within a matter of centimetres.
Spark developed the minicutters from inside and out. It was a question of drawing, calculating and adjusting, again and again. All the parts have a function. There are no superfluous additions. That would make the product too bulky and too heavy. So it became a tool without a housing. A typical case of what you see is what you get, but also visually attractive.
