10 Best Putty Knifes With Reviews – 2017 | ResearchCore

What Is a Putty Knife?

While putty knives can have a variety of functions, their initial purpose was to help smooth putty while installing or repairing windows. Typically, these knives come in different sizes, with bigger knives suited for larger surfaces and smaller, thinner knives developed for more detailed tasks.

How To Use a Putty Knife Properly?

As with any sharp object, whenever you use a putty knife you always want to put your safety first. While it might not seem like it, putty knives can be fairly sharp depending on their intended purpose. Avoid placing your fingers or hands too close to the end and never point the knife towards you.

When using a flexible knife to apply putty you have two options. Firstly, you can apply putty to the knife in an even layer across the blade and then smooth it across your intended surface. The second option is to apply the putty straight on the surface, then smooth it with the knife.

removing wax using a putty knifeNo matter your expertise in construction—whether you’re a painter, a carpenter or a do-it-yourselfer—at some point, you’ll need a putty knife. Owing to the fact that putty knives have a distinct, narrow and/or thin design, they typically work for a plethora of construction and repair tasks.

Although the flexible blade initially made putty knives ideal for spreading putty—hence the name—today its uses have evolved. The knife’s additional uses include operating as a scraper knife, which removes tough debris like plaster and paint.

However, even though these knives can occasionally both scrape and apply putty, not all these tools are created equal. The most important thing to note about putty knives is they come in two versions: flexible knives and stiff knives.

Flexible, or flex, knives are the great for applying and spreading putty. They usually feature very thin blades that make them pliable, creating a very smooth finished product.

On the other hand, stiff blades are about twice the thickness of flex knives and are, typically, more effective at scraping. The thickness of these tools makes them sturdy, allowing users to put pressure on the knife without having the blade bend.

Another distinguishing factor of a putty knife is its size, ranging anywhere from 1 inch to 6 inches. Varying lengths and widths can be used to for bigger, general, applications or more detail oriented tasks.

When it comes to finding the right knife, it’s not always clear which option is right for you. With so many options to choose from it can be easy to make a regrettable purchase. This guide relies on putty knife reviews and extensive research to narrow down the wide selection of products on the market.

So if you’re eager to start your next project and need to find the perfect putty knife—or knives—read on to discover the top putty knife available.
