In what scenario is it acceptable to cut through a knot when sawing lumber?

Cutting through a knot in lumber is generally discouraged because it can compromise the integrity and strength of the wood. Knots are naturally occurring imperfections that can lead to unpredictable cuts, splinters, and even damage to the saw blade. When sawing lumber, maintaining the quality of the cut is essential for safety, durability, and the overall appearance of the finished product. Additionally, knots can create stress points in the wood, which might lead to problems down the line, such as warping or cracking.

The perspective that it is never acceptable to cut through a knot reflects a cautious approach to woodworking and construction, emphasizing the importance of preserving the wood's structural integrity. Utilizing techniques and tools that respect the natural properties of the material can prevent unnecessary complications in the crafting or building process.
