Cutting cardboard with a box cutter is one of the most common tasks in a warehouse, but it can also be unsafe. In this blog post, we will discuss 14 simple safety tips to help you work safely and efficiently with your box cutters.

This includes general principles for safe use, as well as specific tips for cutting corners and scoring points on boxes. If you follow these safety tips closely, you won’t have any problems working with your box cutter.

Tip 1: Sharp Blade

Use a sharp box cutter. A dull blade will require more force, increasing the likelihood that your hand slips off of the box and into the path of the knife. When you cut with a dull edge, it also becomes much easier to tear cardboard rather than cutting cleanly through its surface.

If you have trouble scoring boxes without tearing them, it’s a good idea to have your blade sharpened.

Tip 2: Safety Guard

Make sure the safety guard is in place when not using your box cutter. A plastic or metal safety guard covers the edge of the razor knife and prevents you from accidentally injuring yourself while cutting cardboard boxes, tape, rope, or any other wide variety of objects.

When you are finished using your box cutter, it is important to remember that the blade might still be very sharp!

Be careful not to cut yourself or anyone else when replacing the safety guard on top of your razor knife.

Tip 3: Clearance

Make sure there’s nothing in front of the line before cutting cardboard with a box cutter. Never cut anything if you can’t see where the blade is going. Before using your box cutter, make sure there aren’t any obstructions in front of the line that you want to cut with the knife.

If necessary, move these items out of the way so they don’t get accidentally sliced up by your razor blade.

Tip 4: Flat Surface

Cut against a flat, stable surface when using a box cutter. When cutting cardboard with your razor knife, make sure you have a solid and flatwork area. Avoid working on surfaces that might wobble or be unstable while in use.

Never try to cut tape by holding the edge of the blade flush against the surface of the table. This is dangerous because if your hand slips in any way you can injure yourself.

Tip 5: Corners

Be careful when cutting corners with a box cutter. Whenever possible, score or fold cardboard before trying to cut it. When scoring boxes for easier folding later on in the process, be sure that your score line is at least halfway through the cardboard.

If you try to cut too close to the corner, your blade might slip and cause an injury.

Tip 6: Box Cutter Use

Don’t use a box cutter on corrugated boxes. Box cutters are not designed for cutting into or scoring corrugated cardboard. The corrugated material is much thicker than standard cardboard and requires a specialized tool to cut all the way through.

Tip 7: Holding Paper

Never try to hold down the paper with a razor knife while cutting it. When cutting paper with a box cutter, don’t try to hold down the document or pages you’re trying to slice.

This can cause the blade of your razor knife to get pinched between two sheets of paper and potentially break off inside the tool.

Tip 8: Self-Injury

Never cut toward yourself with a box cutter. Whenever possible, try to avoid cutting boxes or other objects directly towards your body. This is the most dangerous way of using a razor knife because it’s almost impossible for you to see what you are doing.

Even if there isn’t anyone else in the room, you should be careful when using a box cutter.

Tip 9: Carrying and Storage

Never carry or store your razor knife with the blade exposed. Whenever possible, it’s best to keep your box cutter protected by both storing it in its original packaging and covering up the edge of the blade whenever you are carrying it around.

This is a great way to avoid any unnecessary injuries when transporting your box cutter from job site to job site.

Tip 10: Blade Size

Use the right size blade for cutting corrugated cardboard. If you are using a razor knife on multiple types of materials, make sure that you have the appropriately sized blades installed in the tool.

If the blade is too large for your intended use, it can cause damage to whatever you are trying to cut.

Tip 11: Blade Guard Protection

Make sure that the blade guard on top of your box cutter is always in place. One of the most important parts of safe box cutter usage happens before you ever even pick up the tool.

Ensuring that the blade guard on your razor knife is in place and working correctly before you start cutting anything is a fantastic way to avoid any injuries, so don’t forget.

Tip 12: Disposal

Always remember to properly dispose of used blades. If you’ve nicked yourself while using a box cutter, it’s important to remember not to use the razor knife again until you have replaced the blade.

If you try to cut anything with a dull or nicked blade, it can cause injury. Make sure that your box cutter is working properly by inspecting blades before and after each task.

Tip 13: Lighting

Cut in a well-lit area whenever possible. It’s important to remember that when you’re using a box cutter, it can be difficult to see what you are cutting.

If the area is too dark and your vision is impaired, try adding some lamps or lights in order to make sure that there is enough light for you to complete whatever task needs doing.

Tip 14: Safety First

Always store your razor knife in a place that is out of the reach of children. One of the most important box cutter safety tips for parents or business owners to follow is those involving proper storage.

Always remember to keep your razor knives locked up and away from small hands. With these simple precautions, you can avoid any unnecessary injuries when using a razor knife.
