An Overview of Drywall Taping Knife Materials

Drywall taping knives are drywall tools used for spreading “mud” or joint compound. As the name suggests, the knife features a blade and handle. The knife spreads the joint compound over screw and nail indents in drywall. Many people also use drywall taping knives when utilizing fiberglass/paper drywall tape to hide seams. The knives range in size, blade material, and handle design/material. To help you understand your options for drywall knives, we’ve compiled an overview of drywall taping knife materials. Read on to learn more.

Taping Knife Blade Materials

In regard to blade material, you can buy a stainless steel drywall knife or one made from carbon steel or blue steel. Each material has its pros and cons. Here’s what you should know about each of them.

Stainless Steel Drywall Taping Knife

Drywall taping knives with blades made of stainless steel are rust-resistant. When cared for properly, these blades will last decades. Another notable benefit of stainless steel is its strength. The blades are more rigid than others, making them harder to bend and less flexible. However, this feature makes them suitable for large-scale applications where blades shouldn’t bend easily.

Carbon Steel Drywall Taping Knife

If you wish for more flexibility, carbon steel is a better choice than stainless steel. This type of drywall taping knife blade is perfect for feathering and smoothing, among other fine tasks. Carbon steel blades usually come with a “broken-in” feel from the first use. However, carbon steel will rust, introducing unique maintenance challenges.

Blue Steel Drywall Taping Knife

Do you want the flexibility of carbon steel without the cons? You may want to opt for a blue steel drywall taping knife. The only difference between blue steel and carbon steel knives is that the treatment used on blue steel knives helps prevent rusting. The treatment gives the knives a dark bluish color, hence the name. Blue steel drywall taping knives are also flexible, making them a great choice for drywallers who want the best of both stainless steel and carbon steel.

Handle Materials

Blade material aside, drywall taping knives also feature handles made of different materials. Wood handles are popular for their availability, comfort, and durability. They also have an attractive appearance. However, wood handles can be costly and heavy.

Rubber handles may be a better option given their lightweight nature, comfort, and durability. Plus, rubber handles provide a better grip.

Some drywall taping knives also have plastic handles, which are durable and cheap. However, they aren’t as comfortable as rubber handles.


In this overview of drywall taping knife materials, we’ve gone over three common types of drywall knives. Each material has unique benefits, although stainless steel and blue steel drywall taping knife materials stand out the most. Additionally, it’s essential to consider the handle material.
