When you bring a product to the market where your brand name takes over the role of the product name, you do something very well. So almost no one will call an extension knife that way. No, you speak of a Stanley knife. And rightly so, because as Stanley develops and produces these knives, there will not be another person who can match this product. Take for example the FatMax Xtreme Duo Uitschuifmes. This knife is equipped with two different blades that can be changed at the touch of a button. So you can rush through with a job in één movement. The 180 millimeter long knife has a storage space for 5 spare blades and is ergonomically shaped so that long-term work will not be a big burden.
