The OLFA SK-4 box cutter is pretty handy when it comes to slicing through different materials. According to the manufacturer's product description, it can cut materials typically found in packaging and shipping, like cardboard, vinyl, and films. It's particularly good at handling multiple layers of cardboard, which can be tricky for other cutters.
One of its standout features is the self-retracting blade. This means the blade automatically pulls back into the handle after you make a cut, which is a big plus for safety—our research highlights this as a well-loved aspect.
Regarding material durability, while it's fine with different materials, how long the blade stays sharp really depends on what you're cutting and how often. If you're working with tougher stuff regularly, you might find yourself swapping out the blades more often to keep it cutting smoothly.
And just a quick mention, even though it wasn't part of your original question, the SK-4 is designed for both right-handed and left-handed folks. Some left-handed users say it feels a bit awkward at first, but after a bit of practice, they find it works just fine.
Overall, the OLFA SK-4 is a reliable utility knife for cutting everyday materials like cardboard and packaging films, and it's got some solid safety features to boot.
Whether you're left or right-handed, after a short adjustment period, it seems to handle various cutting tasks effectively.
