How to Cut Carpet Properly Using a Carpet Knife

If you want to cut a carpet properly by using a carpet knife, you just need to follow some proper steps. Randomly cutting may ruin your valuable carpet. So knowing well how to use a carpet knife as well as how to cut carpet would save your precious time, energy, and money. Let’s follow the steps.

Start With a Sharp Carpet Knife

All rugs or carpets are not the same. Some are easy to cut while others are tougher to cut than you think. This is why picking the best carpet knife or utility knife for cutting the carpet would be the best decision.

In addition, a heavy-duty carpet knife can withstand pressure and cut precisely. A large, comfortable, and non-slip grip of the carpet cutting knife is the best to cut through. These types of utility knives are highly effective in carpeting and carpet padding.

However, before you start to cut the carpet, it is necessary to equip your carpet cutter knife with brand new blades. Dull blades are not only harder to precisely cut with, but they can also be incredibly dangerous.  

Pro Tips: Do not try to cut carpet with a standard X-Acto knife because they are supposed to use for cutting things like paper and cardboard. This is why you cannot get enough leverage with them.

Separate the Carpet into Smaller Pieces

If you buy the whole roll of the carpet, it is essential to cut it into necessary smaller pieces. The large roll can be difficult to work with. For this reason, slicing the carpet into smaller sizes makes the job done easier and faster as well.

Should I cut the carpet randomly into smaller pieces?

No, of course, not. Just measure the carpet according to your plan or need, and then proceed with cutting the carpet. However, you will then be able to flip the carpet over and can move it around easier to make the precision cuts.

Pro Tips: Always try to cut off the carpet an inch or half more than you need for the job at hand. The old adage, “measure twice, cut once” is still true. Once you cut the carpet cannot be undone. So think twice.

Make Precision Cuts on the Backside

Never make the mistake of cutting the actual carpet side. Carpeting has a mesh backing that is made of polypropylene. Though the carpet fibers are not that difficult to cut, the carpet backing is incredibly tough to cut.

So, which side is to cut first? Well, it is great to cut on the backside first. You can get the knife in the backing first and then can bypass the fibers.

By cutting on the rear, you can get the blade in the backing first and can bypass the fibers. You can generally cut the fibers on the top after you have made your accurate cuts on the backing.

The backing is also flat, so you can separate your cut lines where you can see them.

Attempting to precisely cut on the fiber side is excessively troublesome and you risk marking up the carpet itself. On the backside, you can make as many marks as you need and they won’t show in the final result.

Use a Double-Blade Wall Trimmer along with Stopping Points

You have successfully put the carpet in place and now you have to trim some excess along the walls.

However, cutting this excess part can be really tough to precisely cut in a straight line with a utility knife. This is why, before placing the carpet in the room, cutting backing would be easier and you should do this. Because once placed in the room can be quite difficult to do that.

In addition, if you are going to cut accurately along the walls and stopping points, a double-blade wall trimmer would be very useful, helpful, and effective.

This double-blade wall trimmer has a handle and a fence that runs along the wall. You will get good leverage on the fiber side, for this reason, you don’t need to turn it over.

A good carpeting knife can cut the carpet without fraying and this is why you can learn more about how to cut carpet without fraying.

With a double-blade wall trimmer tool, instead of the utility knife, you can make clean, accurate cuts along walls and thresholds.

Carpet tucking knife vs carpet cutting knife

In this carpet tucking knife vs carpet cutting knife discussion, we will know what this tool is and what are they used for.

A carpet tucking knife is supposed to use for snugging the carpet inside the inner openings in the edges of the wall. It is very strong and sturdy and barely bends or breaks. This tool has a curvature-style blade. The blade on this tucking knife is mostly fixed. The curvature part of the knife can act as a hook to remove the carpet.

The carpet cutting knife is mostly seen to the contractors to cut through drywall and carpet. However, this carpet knife helps users to install new carpets or flooring beneath them.

Carpet Knife Usage and Safety

Carpet knives in our daily life are essential tools to cut normal materials. Usually, a carpet knife is made of steel that is equivalent to carbon steel in terms of hardness.

Due to a carpet knife’s hardness and sturdiness, you can cut through many materials such as asphalt, upholstery wool, open-meshed tennis-court netting, polyethylene, linoleum, vinyl tile backer board, and carpet fiber.

Speaking of the sharpness of the carpet cutting knife, the blade is incredibly sharp and one can easily be injured if the user is not careful enough either in handling them or keeping the blade exposed without retracted or folded, or storing them in a secure place.

It is highly suggested that when a user is using a carpet knife, he must wear a pair of gloves and glasses for protection.

This is also recommended to keep a pair of hand shears by the side to cut out the carpet from awkward areas such as underneath heavy furniture.

Remember, a sharpened carpet knife can make your job done easier, quicker, and smoother. So, always take care of it. So, always try to keep your carpet cutting knife sharpened for maximum efficiency.
