Why Kerfed Wood Should be Your Choice for Flexible Architectural PanelsFebruary 6, 2023
Ever wonder where we got our company name from? Kerfkore is based on the word kerf, which is a technique in woodworking used to create bends and curves. For many, woodworking is associated with straight and traditional designs, but with kerfing, we can create elegant, dynamic, and modern woodworking that defies expectations. So, where did kerfed wood originate and why should it be your choice when working on your next curved project?
What is a kerf cut?
A kerf cut refers to the resulting slot when a cutting process removes material. Traditionally, a kerf was defined as the width of a saw blade and how much wood was removed, before other methods and materials were used.
In woodworking, when enough kerf cuts are used in succession and spaced appropriately, it’ll create wood that is flexible. It works sort of like a bendable straw – the creases in the bendy part of the straw allow the straw to flex, without causing too much stress on the material.
It’s tough to tell exactly where and when the kerf cut was invented. Woodworking is one of humanity’s oldest industries, and the kerf-cutting technique, by all records, seems like it’s been around for a while. It’s at least old enough to be referenced in the University of Michigan’s Middle English Compendium as “kirf” and referenced in the Oxford Old English dictionary as “cyrf.”
Why kerfed wood?
While it’s an age-old technique, it can be used to create incredibly modern shapes. The elegant curves of wooden instruments like grand pianos and acoustic guitars can be executed with kerfing, as well as archways, curved ceiling baffles, and a plethora of other eye-catching architectural designs.
The possibilities are endless. The psychological benefits of arches and curves have been well-documented. There is something natural and welcoming about curves, which kerfing allows us to achieve with wood because it creates stability and consistency.
There are some alternatives to high-quality kerfed wood such as using thinner, bendable wood like bending luan. But it’s not without its drawbacks – we wrote an article comparing bending luan to Kerfkore, but here are the quick takeaways.
- Bending luan is known for its high variation in quality and bendability. Some sheets of luan will bend further and be less durable than others, potentially creating a misadventure of trial and error for fabricators trying to achieve a desired bend radius.
- These quality issues also contribute to the overall time spent on the project as well as potentially higher costs. In general, luan plywood is cheap, but fabricators may lose multiple sheets due to breakage.
For a lot of projects, it’s hard to replace the dependable, high-quality wood that can be achieved with kerfed wood. It allows you to create complex and more demanding designs such as S-shaped curves, where bending luan can struggle to do so.
Self-Kerfing vs. Pre-Engineered
At Kerfkore, we specialize in creating pre-engineered architectural panels that are specially built to be quickly implemented, but DIY kerfing is a popular and viable option for small projects.
If you’re planning on self-kerfing, be aware that as the scale of your work grows, so will the demands on your materials, time, and costs. That’s where pre-engineered kerfing really shines. It allows you to focus on putting together the rest of your project, instead of tying up time, equipment, and manpower on the tedious work of kerfing.
Plus, with pre-engineered kerfed wood you can rely on precision cutting and high-quality materials built to your exact needs, which is often required for larger, professional works. On the other hand, DIY kerfing is a challenging process that can result in wasted wood, telegraphing, and uneven surfaces, if not executed properly.
Our pre-engineered kerfed wood also eliminates the bending radius guessing game, you’ll know exactly how much bend is possible before incorporating the wood into your project. For projects that call for multiple panels, with a uniform bend – this is an integral feature.
That’s not to say we’re anti-DIY, but when a project calls for professional precision, quality, and your time is limited, then pre-engineered kerfed wood like Kerfkore is your best bet.
