Knots and knotholes are not hazards that contribute to cutout accidents because gaffs are shaped to deal with them.

• A. True
• B. False
• C. Not applicable
• D. Not sure

Answer: (B)

Knots and knotholes remain hazards because they disrupt the wood’s grain and density, creating spots where cutting forces behave unpredictably. When the cut reaches a knot or a hollowed knot area, the blade or tool can slow, snag, or bind, which can pinch the workpiece, cause twisting, or even kick the piece back toward you. Gaffs or other design features on a tool can help reduce catching, but they don’t eliminate the risk. The wood around a knot is inconsistent—grain swirls, fibers break unevenly, and resin or moisture can make the surface grabby—so you can still experience binding, unexpected chatter, or chips tearing away.

Because of that, plan to avoid knots when possible: position the cut to stay clear of them, or reinforce and support the workpiece so movement is controlled. Ensure the blade is sharp for the material, apply steady, even pressure, and keep your hands well clear of the cut path. If you encounter a knot during a cut, pause and reassess rather than forcing the cut, since forcing increases the chance of a loss of control.

Knotholes also pose hazards by creating voids that can weaken the cut line and lead to unpredictable material behavior as the tool passes over them. In short, while tool design helps, knots and knotholes are real hazards that can contribute to cutout accidents.
