Which item is not recommended for repairing a stock?

The blocking chisel is not recommended for repairing a stock because it is primarily designed for precise cutting and shaping of wood rather than for repairs. When repairing a stock, especially in woodworking, the focus typically relies on methods that reinforce the joint or bond materials effectively.

Wood glue is a common choice for repairs due to its strong bonding capabilities when adhering pieces of wood together. Epoxy resin, which creates a very strong bond and is particularly effective for fill and repair in more complex or load-bearing scenarios, is equally appropriate. Clamps are essential for holding glued pieces together until they cure, ensuring a solid bond is formed without movement.

Using a blocking chisel in a repair context might introduce unwanted material removal or alteration to the stock, which can compromise its integrity or function. Therefore, tools and materials specifically intended for bonding or structural support are preferred in stock repair.
