Ventilation pipe cutter
Sometimes the little things, really are making a difference. You can see it these days in daily life — The corona virus is pretty small, but has a bif effect in the world.
The ventilation pipe cutter which I show in my video below is a really good example how a small item can really change your everyday work. Normally ventilation pipes are beeing cut a regular knive and the edge is more or less crooked.
The ventilation pipe cutter, which is directly pushed into the groove, holds itself with two seperators and cuts easily along the rim.
Check me in the video where I explain a bit more about that fabulous tool.
