Factors to Consider When Choosing the Best Putty Knife

Any good home improvement or woodworking project starts with the proper tools. And while there are a lot of different tools that can come in handy around the house, one tool that is often overlooked is the putty knife. 

But, if you’re not using the right product for the job, it can make your project a lot harder than it needs to be. In order to choose the best putty knife to use for your project, there are a few things you’ll need to keep in mind. 

Take time to consider the following factors, and you’ll be sure to choose the quality putty knife for your needs.

1. Size

When it comes to putty knives, size definitely matters. After all, you don’t want to be stuck trying to scrape away excess putty with a blade that’s too small. 

But at the same time, you don’t want a product that’s so big that it’s difficult to maneuver. So how do you choose the right size product for the job? Here are a few factors to consider:

The type of putty you’re using: If you’re using a thicker, more viscous putty, then you’ll need a larger blade to disseminate it evenly. On the other hand, if you’re using a thinner putty, then a smaller blade will suffice.

The surface area you’re working with: If you’re patching up a large hole, then you’ll need a correspondingly large size of the product. Conversely, if you’re just touching up a small crack, then a smaller knife will do the trick.

Your own personal preferences: Some people prefer larger blades because they provide more coverage with each stroke. 

Others find smaller blades to be more nimble and easier to control. Ultimately, it’s up to you to decide what size putty blade feels right in your hand.

2. Material

The material of a putty knife can be the difference between a successful repair job and an unsuccessful one. 

For example, when you are using a putty knife to apply spackle to a hole in your wall, you will want to choose a putty or spackle knife that is made of a durable material that can withstand repeated use. 

However, if you are using a product to apply a finish to a piece of furniture, you will want to choose a knife that is made of a softer material so as not to damage the surface. The following are some of the most common materials used in putty knives:

Plastic: 

Plastic putty knives are the most common type of knife on the market. They are lightweight and can be used for a variety of tasks. 

If you are selecting a plastic blade, it is important to select one that is constructed of durable plastic. This will ensure that your butter knife will last for a long time.

Steel: 

Steel putty knives are more durable than plastic knives and can be used for tougher tasks. The uses for a steel putty knife are nearly endless. 

Stainless steel and carbon steel material are the two most common types of steel used in putty knives. These material options offer different levels of durability.

So, depending on the task at hand, you can choose either stainless steel blade or plastic construction for your putty blade. 

Regardless of the material you choose, you should ensure that it is durable and can withstand repeated exposure. This will prolong the life of your knife and ultimately save you money.

3. Flexible or Stiff

Deciding whether to go with a stiff or flex putty knife is not as black and white as one might think. It really depends on the project you’re undertaking. 

You need to know what the job is that you will be using it for. For example, if you’re going to be using your putty knife on a curved surface, then you will need to select a flexible knife. The flexibility of the blade will allow you to follow the contours of the surface without damaging it. 

Furthermore, if you are working with a soft material such as putty or dough, you will need a flexible knife. With this flexibility, you will have greater control over the material, and you will reduce the chance of accidental gouges. 

Generally speaking, a flexible putty knife is better suited for delicate tasks. For applying putty to soft surfaces such as drywalls or woodwork, a flex putty knife is a way to go.

On the other hand, if you’re working with a harder material, like concrete or stone, then you will want to go with a stiffer putty blade. 

The stiffness of the blade will give you more leverage when chipping away at the material. Also, if you are working with putty or dough that is on the harder side, then you will want to use a stiffer knife. 

In addition, the blade’s stiffness will prevent the material from being inadvertently pushed around. In order to remove paint or old caulk, a stiff putty blade is ideal.

So, as you can see, there is no clear-cut answer as to whether you should use a stiff or flexible blade. It really depends on the project you’re working on. Ultimately, it is up to you to decide which type of blade, (flexible and stiff versions) will work best for the task at hand.

4. Handle

In most cases, the handle of a putty knife is overlooked, but it is an indispensable part of this tool. In order to make use of the knife effectively, it is important to choose a handle that is comfortable for you. 

When selecting a putty blade, you should pay close attention to the handle. In terms of handles, you need to consider the length, width, and grip. 

Make sure that the handle length is suitable for your hand size. Also, the width of the handle should be comfortable for you to hold. 

Lastly, the grip should be slip-resistant so that you can maintain a firm grip on the knife while you are using it.

5. Hang-Hole

When you’re done using your putty knife, you’re going to want to store it somewhere safe. But where exactly should you store it? The most obvious answer is in a drawer or toolbox. 

However, if you’re like most people, your drawers and toolboxes are already overflowing with other tools and supplies. So, what’s the best way to store your putty knife? The answer is simple, get a putty blade with a hang-hole.

A hang-hole is simply a small hole in the handle of the putty knife that allows you to store it on a hook. 

This is a great way to store your putty blade because it keeps it within easy reach and prevents it from taking up valuable space in your drawers or toolbox. 

Therefore, when you are looking for the best putty knife for wood filler or any other use, you should search for one that has a hang-hole. Your life will become much easier and you will be able to keep your workspace more organized.

6. Rust-Resistance

If you are going to be using your putty knife on a regular basis, then you need to choose one with a rust-resistant blade. This is especially important if you live in an area with high humidity or if you plan on using your putty blade in wet conditions. 

A rust-resistant blade will ensure that your putty knife lasts for a long time without showing any signs of wear and tear. So, next time, when selecting the best putty knife for drywall or any other task, make sure that it is rust-resistant.

7. Solvent-Resistance

In addition to being rust-resistant, the best putty knife will also have solvent-resistant blades. 

This is important because you will likely be using solvents (such as paint thinner or mineral spirits) when cleaning your putty blade. If the blade is not resistant to these solvents, then it will become damaged and stained.

8. Washable

Washable

Another important feature to look for in the best putty knife is a washable blade. This is important because you will need to wash your putty blade on a regular basis, particularly if you are using it for painting projects.

When you are looking for the best putty knife, you should also look for one that is reusable.
