The Difference Between Rift Oak and Flat Cut Oak (or Plain Sawn Oak)

Natural wood kitchen cabinets will remain stylish and sophisticated for years to come. But wood is valued for more than just its appearance. People are drawn to the safety, strength, and durability of the material, with oak being one of the best indicators of these qualities.

In addition to its strength and durability, oak veneer is also versatile. Despite its hardness, it can be easily worked with tools, painted, or varnished. This versatility is why oak veneer is frequently used in the production of kitchen cabinets.

However, choosing the right cut is a crucial factor that influences the wood’s appearance and properties. Rift-cut oak and flat-cut oak differ in how they are sawn, which affects their texture and performance characteristics. Let’s explore these types of cuts and how they differ.

What is Rift Oak

Rift oak is created through the radial sawing process, where the sawing plane is perpendicular to the growth rings that form the wood's grain. This technique produces a uniform and precise grain pattern, free from the "flaming" patterns often associated with other methods of processing. The resulting veneer has a more minimalist and restrained appearance.

Rift Oak Characteristics

Rift oak possesses certain characteristics that directly impact the furniture made from it.

Due to its even fiber distribution, rift oak is naturally resistant to warping and cracking. It also resists liquids, preventing them from easily penetrating. The wood also holds paint tightly and wears evenly over time, making it a reliable choice for durable furniture.

However, like most woods, rift oak is susceptible to shrinking or swelling with changes in environmental humidity. This is why it should always be finished with a protective coating against moisture and weather changes.

Rift sawing uses only about 40% of a log to produce veneer, resulting in significant material waste. Given the environmental impact of logging, this inefficiency is a cause for concern. Additionally, oak's popularity for its sustainability has contributed to its growing scarcity, making it increasingly limited. For these reasons, rift oak should be valued, and people are encouraged to choose high-quality, durable cabinets to minimize environmental impact.

What is Plain Sawn Oak

Flat-cut oak, also known as plain-sawn oak, is another woodworking method. In this process, the timber is cut parallel to the tree’s growth rings. This technique allows the rings to appear at varying angles, creating a distinct grain with more pronounced curves. It is the most common and economical cutting method, producing a characteristic grain pattern that is widely recognized and appreciated.

Flat Cut Oak Characteristics

Because the rings are exposed during the sawing process, the "flame" or "wave" pattern is prominently visible on plain-sawn oak veneer. This distinct grain pattern can also be seen on cabinet fronts, tabletops, and other furniture pieces.

Like other types of wood, flat-cut oak is subject to moisture-related changes. While it also shrinks and expands, these changes primarily occur in its width. As a result, adjustments may be necessary during processing and manufacturing, so cabinets won’t need fixing upon their arrival.

One of the advantages of this method is that the entire log is utilized, significantly reducing waste and lowering production costs. This efficiency makes plain-sawn oak a more affordable option from a financial perspective.

How to Distinguish Rift Oak from Flat Cut Oak

Based on what we’ve learned about the characteristics of rift oak and flat-cut oak, we can identify several key differences between them.

1. Sawing Method
This is the defining factor for both types of wood, but it's worth reiterating. While plain-sawn oak is cut parallel to the axis, rift oak is cut perpendicular to it.

2. Pattern
The sawing method also affects the resulting grain pattern. Flat-cut oak displays the typical wood grain with characteristic wavy lines, while rift oak features a series of thin, parallel lines.

3. Resistance
Like other types of wood, flat-cut oak undergoes minor moisture-related changes, primarily in its width. These natural variations are considered during processing and manufacturing, ensuring cabinets arrive stable and ready for use.

4. Environmental Friendliness
The more complex sawing process of rift oak results in significant waste, as not all of the wood is used. In contrast, flat-cut oak leaves less waste, making it a more environmentally friendly option.

5. Cost
The sawing process for rift oak is more complex and requires high-quality, defect-free logs, which increases its cost slightly. However, this has only a minimal impact on cabinet prices. Plain-sawn oak, being more accessible and yielding more material, is more affordable.

In the end, while visually distinguishable, these types of oak differ in other key areas that will help guide the choice of material for specific projects.

What to choose?

The characteristics of rift oak and flat-cut oak are reflected not only in their production properties but also in their practical applications.

If you're aiming to create minimalist furniture, both in design and finish, rift oak is the ideal choice. The uniform lines and subtle grain make it perfect for a clean, minimalist aesthetic. This will give kitchen cabinet fronts a monochromatic look, creating a smooth, seamless effect.

If you prefer the wood to showcase its natural beauty with visible grain and curves, then plain-sawn oak is the way to go. Even in a minimalist kitchen design, the vibrant grain can serve as a striking feature. It adds a sense of warmth and naturalness, which, when paired with modern design elements and appliances, creates a beautiful contrast that highlights the wood's authenticity.

Both rift oak and plain-sawn oak are in high demand and widely used in the construction of kitchen cabinets and other furniture. Each has its own set of advantages and drawbacks, but both produce equally beautiful and durable results. Ultimately, they serve the same purpose — and that’s what makes these materials so valuable.

FAQ

What does rift mean in wood?

Rift refers to a specific method of sawing wood where the cut is made perpendicular to the growth rings. This technique creates a uniform, linear grain pattern, commonly seen in rift oak.

Is rift oak expensive?

Yes, rift oak is generally more expensive due to the complex sawing process and the high-quality logs required. Additionally, this method produces significant waste, further increasing its cost.

What is flat cut wood?

Flat cut wood is produced by sawing logs parallel to the tree’s growth rings. This method reveals a distinctive wavy grain pattern and is widely used for its affordability and efficiency.

Is flat cut wood the same as plain sawn wood?

Yes, flat cut wood and plain-sawn wood are the same. Both terms describe the process of cutting logs parallel to the growth rings, creating the characteristic flame or wave-like grain pattern.
