Hello Kayla! Thank you for your recent purchase and for taking the time to leave a review :-) I spoke with my product manager, who shed a little more light on how to use this tool. The slot is designed to be wider than the squeegee blade since not all blades come the same thickness but also because the blades expand a bit when they are soaked with ink. When using the tool, you have to apply a bit of pressure on one side at a time to get the tool to scrape off the ink. Please try that method and see if it helps the tool be more efficient. Also, as always, feel free to reach out to us for assistance when ever you need clarification on a product - we are here for you! Happy Printing - April w/ Ryonet
