Not as sharp as I've had before, still have to apply a lot of pressure to cut just 120 GSM paper. But it's easy to use and comes with extra blades. Blades wobble about unless you fully tighten it, but once tightened, it doesn't move. Slim line and easier to use than a traditional craft knife.. but still trying to work out if it's cost effective over a traditional craft knife that comes with one blade that you can snap off when you need a more sharper blade.
