A collapsible hand saw features an elongated tubular frame member with a hollow interior that runs longitudinally therethrough. First and second arms are removably engaged to the tubular frame near first and second ends of thereof, to span outward from an underside thereof in a common direction. Each arm, near a distal mounting end thereof is configured for selective coupling to a bowsaw blade at a respective mounting hole therein near a respective end thereof. An adjustable tensioner is connectable between the frame member and the first arm, and when tightened, pulls the respective mounting end of said first arm away from the second arm and toward the first end of the frame member to tension the blade. The hollow interior of the frame member accommodates simultaneous storage therein of at least the first and second arms, the adjustable tensioner, and one or multiple blades.

The utility model provides a light saw horse which comprises a main beam and a supporting assembly, the main beam is hollow, an assembly opening is formed in the bottom of the main beam, the supporting assembly is rotationally installed in the assembly opening, the light saw horse further comprises a bearing seat, the bearing seat comprises a containing plate and a jacking plate, and the jacking plate is installed on the side face of the main beam and connected to one end of the containing plate. Triangular plates are arranged on the two sides of the containing plate and abut against the abutting plate. By optimizing the structure of the bearing seat, the loading capacity of the bearing seat is effectively improved, the possibility that the bearing seat is scrapped is reduced, and the bearing strength of the saw horse is improved.
