Which action would reduce the likelihood of Venetian blind artifact appearing?

• A. Retracting the block holder shaft
• B. Reembedding the tissue
• C. Moving to blade section
• D. Allowing drain

Answer: (A)

Venetian blind patterns come from irregular, parallel markings on a section caused by how the blade interacts with the block during cutting. Retracting the block holder shaft reduces downward pressure and allows the knife to approach the block with a clean, fresh surface, minimizing blade chatter and tearing that create those uniform, narrow bands. In other words, easing the contact and resetting the blade’s approach leads to a smoother cut and fewer parallel lines across the section.

Reembedding the tissue tackles embedding issues or poor adhesion, but it doesn’t directly fix the mechanical cutting conditions that produce this pattern. Moving to the blade section or allowing drain don’t address the underlying blade–block interaction responsible for these parallel markings.
