Se-wari Kerfing
When lumber dries it tends to check, leaving unsightly cracks in the wood surface. This makes the wood unsuitable for Japanese tea houses or sukiya-style residences. How can you prevent sawn lumber from cracking? Japanese lumber mills have developed a technique for controlling the checking, ensuring that cracks appear only on the least visible side of the lumber. This time-intensive technique called sewari kurfing is usually applied to the high-quality wood used in timber frame homes, but it can also be applied to reclaimed lumber and pressure treated lumber.
