What term is used to designate the best grade of plain-sawed oak flooring?

The term "Clear" is used to designate the best grade of plain-sawed oak flooring. This classification indicates that the wood is of superior quality, exhibiting minimal or no imperfections, such as knots or other blemishes. Clear grade oak flooring is prized for its uniform appearance and natural beauty, making it ideal for high-end applications where aesthetics are a priority.

Select grade, while still high quality, may contain some minor defects that do not detract significantly from its overall appearance. Common grade represents a lower quality with more visible imperfections and flaws, making it less desirable for applications where appearance is crucial. Quality is a more general term that does not specifically define the standard like "Clear," and thus does not pinpoint the highest grade in this context. This understanding of grading terminology is essential for selecting the right materials in carpentry and flooring projects.
