Already have a lot of craft knife obsessed, this is but for 10 years the best. Also have 2 of Würth (What exactly corresponds to, except for the color and the shape of the blade slider.) If you have practice with Cutter knives, that's übehaupt not tragic that there is no stop when you push the blade back. The faster can be change the blades! Also part of the magazine in my opinion is not as easy or difficult to move to pull out. The blades are really great. In membrane films (in the window) but also the fairly quickly dull. But in my opinion is normal after. Therefore, I would now deduct any point.
