A reciprocating blade apparatus includes a pair of reciprocating blades stacked on one another in a thickness direction. Each of the blades includes a base as a flat plate extending in a longitudinal direction, and a plurality of teeth protruding in a direction intersecting the longitudinal direction. A transmission case of the reciprocating blade apparatus also includes a reciprocating member having a joint detachably coupled to the base, the reciprocating member being reciprocably supported in the longitudinal direction. A blade support member is attached to the transmission case and configured to sandwich bases of the pair of reciprocating blades therebetween to allow the pair of reciprocating blades to move in the longitudinal direction. The blade support member holds a space to accommodate the pair of reciprocating blades and is independently attached to the transmission case. The pair of reciprocating blades is detachably attached to the blade support member.

A garden shears has a handle, a first cutting member, a handgrip, a second cutting member, an intermediate member and at least one driving member. The handle secures the first cutting member and is pivoted to the second cutting member by the second shaft hole, the handgrip secures the intermediate member, the third shaft hole is pivoted to the first shaft hole, the first end of the driving member is connected to the second connecting aperture of the intermediate member, the second end is connected to the first connecting aperture of the second cutting member, therefore, the first shaft hole, the second shaft hole, the first end and the second end form a four-bar linkage state. In addition, the evading groove of the handle is configured for accepting the second end, thereby the expanded swing range increases the maximum opening angle of the blade and the knife anvil.

A drive manipulation member is configured to be allowed to move to a drive position when an interlock member is at a first position and to be prohibited from moving to the drive position when the interlock member is at a second position. The drive manipulation member is supported rotatably about an axis with respect to the second housing, and is provided with first and second portions extending from the axis in different directions. The first portion is configured to be manipulated by the user. The second portion is provided with a switch operation portion configured to operate a switching unit and an interlock engaging portion configured to engage with or contact with the interlock member. The switch operation portion and the interlock engaging portion are located at different positions from each other in a direction parallel to the axis.

A hand operated shearing tool, comprising a first unit (1) comprising a first blade (11), the first blade (11) comprising a first cutting edge (112); and a second unit (2) comprising a second blade (21) and a second handle (22) connected to the second blade (21) at a proximal end (211) of the second blade (21), the second blade (21) comprising a second cutting edge (212), wherein the second unit (2) is connected rotatably to the first unit (1) about a first rotational axis (Ri) defined by a first pivot (3), the first pivot (3) comprising a first pin (31) penetrating the first blade (11) and the second blade (21); the first pin (31) is connected to the first blade (11) so that displacement of the first blade (11) in relation to the first pin (31) in a direction parallel with the first rotational axis (Ri) is prevented; the second handle (22) is connected to the second blade (21) so that rotational movement of the second handle (22) in relation to the second blade (21) about a second rotational axis (R2) is allowed; the second rotational axis (R2) is defined by a second pivot (4) interacting with the second blade (21) and the second handle (22) and being arranged at a distance (D) from the first rotational axis (Ri) in a direction away from the cutting edge contact point (P); the first pin (31) is arranged to penetrate the second handle (22) through a through hole (221) arranged in the second handle (22); the diameter of the through hole (221) is greater than the diameter of the first pin (31) for allowing movement of the second handle (22) in relation to the second blade (21) in a direction transversal to the first rotational axis (Ri); the through hole (221) has afrusto-conical shape at the end of the through hole (221) opening in the direction away from the second blade (21); the first pivot (3) comprises a frusto-conical shape arranged coaxially with the first pin for interacting with the frusto-conical shape of the through hole (221); as a result, the second handle (22) is arranged to exert a compressive force (F.sub.2) to the second blade (21) due to a shearing force (Fi) between the second handle (22) and the second blade (21) when the shearing tool is moved from the open position towards the closed position; and due to the compressive force (Fi), the second blade (21) is driven towards the first blade (1
