Paper Cutter

Back-to-school season is here, and those endless schedules and name tags are driving everyone crazy. So, I've designed a paper cutter for A4-sized paper and smaller.

• First, determine your craft knife blade type: Three common 18mm blades exist (thickness varies). If you have 14 blades, each is 5mm wide; 10 blades, 7mm wide; or 7 blades, 10mm wide (I only have 5mm and 7mm blades).
• Print only the slider corresponding to your blade type.
• Use the printed blade breaker to snap off the appropriate blade: For slider 1 (7mm unidirectional), snap off one 7mm blade (you can use the first one as well); for slider 2 (10mm unidirectional), snap off two consecutive 5mm blades/one 10mm blade; for slider 3 (10mm bidirectional), snap off two 5mm blades.

• Insert the blade into the lower slot of the slider until it stops, ensuring the blade tip faces the small end of the slider. If loose, briefly heat the blade tip with a lighter and then use pliers to insert it (carefully, the heated tip is extremely sharp).

• Connect the main body of the cutter, inserting the slider into the track (from the middle), again paying attention to the blade direction (unidirectional sliders).

• Insert the paper, aligning it with the guidelines, and quickly move the slider to cut. (Unidirectional blades are recommended, thinner blades work best. With bidirectional blades, ensure alignment for optimal cutting results).
