What To Look For When Choosing Drywall Taping Knife


In this section of the article, we will take a look at the features that are crucial for a drywall knife to work properly.

Size

Choosing the right size knife for the task is crucial. A 6-inch knife can do things a 12-inch knife never could and vice versa.

For drywall taping, both large and small knives are required. We recommend getting at least one 6-inch drywall knife and one 12-inch drywall knife so that you can efficiently tape and float the mud.

A 6-inch putty knife is great for taping, which is why it’s most commonly referred to as a drywall taping knife. It does a good job at filling the joints and generally all taping drywall tasks.

Since it has got a curved blade shape, it can easily get into corners and help to wipe the excess mud.

It’s also good for spreading the mud, scraping chunks of mud, wiping, and hand coating.

What it isn’t good for is floating. This is where we need to use a bigger knife, preferably above 10 inches and ideally between 12 and 14 inches.

Smaller knives can’t spread a thin coat of mud without making a mess. Larger drywall knives can give you a smooth and much more subtle hump than the smaller knives that tend to make abrupt humps that look messy.

For drywall finishing work, both of these are necessary. You can’t get away with using just one of them, and we always recommend going for a few in-between-sized drywall knives for an easier application and better results.

Consider going for a 4-inch and 8-inch knife as well. When you get a hang of drywall finishing, those will make a whole lot of difference for certain applications.

Weight

drywall taping knife

The weight can make or break the drywall knife. If the knife is too light you can’t get enough pressure, while on the other hand, a knife can be difficult to maneuver when too heavy.

Generally, you will find bad drywall knives to be heavy and the good ones lightweight. A quality drywall knife will have lightweight plastic, aluminum, and metal parts which make it easier to handle.

Going for a lightweight model reduces hand fatigue when working with the knife for extended periods.

Blade

The blade of the drywall knife should be made of stainless steel since it will be in contact with water a lot. Carbon steel blades aren’t bad, but they don’t have as good corrosion and rust-resisting properties as stainless steel models.

The blade should be able to flex to apply and work with the mud easier.

Always go for the polished blade models. Those are much easier to clean and maintain. They will save you a lot of time and frustration.

Smaller drywall knives up to 6 inches need to have a curved shape that gets more curved down the handle. This kind of shape allows you to get into corners much easier and wipe off the excess mud.

Bigger drywall knives that are over 10 inches sometimes have a useful feature where the blade flares out to the edges. This gives you much easier access to the corners that are usually hard to reach. If you find a drywall knife with this feature, we recommend going for it.

Handle

drywall knife

Handle makes 50% of the knife and is as important as blade. If you get a knife with a perfect blade but a faulty handle, you can consider your money wasted.

We recommend going for a full tang handle. Those are the handles where the forged blade extends all the way to the butt of the handle. Those handles are sturdier, easier to control, and last longer than partial or no tang handles.

Consider the ergonomics of the knife handle. If the knife doesn’t feel comfortable when working for extended periods, it should be avoided. A curved ergonomic grip handle made from rubber or plastic is what we mainly use and recommend.

The last thing to note before choosing a knife handle is the weight balance of the handle and the blade. They should be roughly the same weight, with the handle being only slightly heavier. The overall weight of the handle and the drywall taping knife should be light.

Hammer End

The Hammer end is a metal part of the drywall knife that is located at the butt of the knife. This part is used for setting drywall nails and is very handy to have.

The hammer end should be very sturdy and impact and drop resistant. It needs to be able to withstand the banging pressure that will be applied to it.

While not necessary, this is a useful add-on to a drywall knife. It’s a bonus that you get with the knife and is not a primary deciding factor when the quality of drywall knife is concerned.
