Segmented saw

A segmented tool, comprising:

• a first segment having a blade extending within a working plane,
• a second segment having a blade extending within the working plane for selective connection with the first segment, wherein at least one of the first and second segments includes a working surface defined along an end of the corresponding blade along the working plane, and
• a connection system comprising complementary portions of each of the first and second segments for engagement together to selectively connect the first and second segments to define a working length along a longitudinal direction along the working plane, the complementary portion of one of the first and second segments including a latch extending with a latch head for engagement with a key of the other of the first and second segments, the latch configured for resilient lateral deflection perpendicularly away from the longitudinal direction, out of the working plane, to permit the latch head and the key to misalign with each other to pass each other along the longitudinal direction, one of the first and second segments including a connection head and the other of the first and second segments including a receiver configured to receive the connection head, the connection head and the receiver collectively defining a fulcrum connection by engagement therebetween to permit pivoting of the first and second segments relative to each other, within the working plane, about the fulcrum connection to pass the latch head and the key relative to each other to selectively interlock the first and second segments.
