Blade guards for power tools such as table saws are disclosed. The blade guard may include a shroud that pivots up and down to allow a workpiece to move past the guard, a dust collection channel, and a pivot joint which maintains the dust collection channel in an operable condition as the shroud pivots up or down. The guard may also include a wood stop and anti-kickback pawls. The blade guard may be part of a dust collection system and may be connected to a vacuum system by a conduit such as a flexible hose.

A sheet cutting device includes a stage including a placement surface on which a to-be-cut sheet is placed; a strip-shaped fixed blade that is provided in one end portion of the stage; a movable blade that works together with the fixed blade to cut the sheet placed on the placement surface of the stage gradually from one end portion of the sheet to a different one end portion; and a support section that is located between the one end of the fixed blade and the other end in such a way as to be closer to a vertically downward side than the fixed blade and be closer to a vertically upward side than a bottom surface of a waste box placed closer to the vertically downward side than the fixed blade, to temporarily support part of a remnant generated after cutting by the fixed and movable blades.
