An apparatus for fixing a saw blade and a knife plate of a saw grinding machine includes a driving device including an axis; and a fixture plate having a first end and a second end. The fixture plate includes a connective hole coupled to the driving device, and a coupled portion defined at the first end thereof. The saw blade is pivotally connected to the axis of the driving device, with the saw blade and the fixture plate moved with respect to the driving device simultaneously. The knife plate is coupled to the coupled portion of the fixture plate and includes a blocked side formed on a side thereof, with a vertical distance between the blocked side and the saw blade maintained to be fixed.

Table saws are disclosed. The table saws can include a blade, an arbor, an arbor block, an elevation carriage, and a latch that connects the arbor block and the elevation carriage. The arbor block can have a first position in which the latch connects the arbor block and the elevation carriage, and a second position in which the latch does not connect the arbor block and the elevation carriage. The arbor block can pivot from the first position to the second position upon the occurrence of a retraction force. The table saw can include an actuator to cause the occurrence of the retraction force, and detection electronics to detect contact between the blade and a person. Woodworking machines with detection and reaction systems are also disclosed. A reaction system can include an explosive that causes retraction of a cutting tool.
