Tool and connection therefor between working portion and handle portion thereof

A device for cutting, comprising:

• a cutting blade formed of metal and having a forwardly disposed toothed portion and a rearwardly disposed tapered shank portion terminating in a rearward end surface, wherein a hole is formed in said cutting blade portion;
• and
• a handle portion formed of plastic material and provided with a tapered slot defined therein for accommodating said tapered shank portion of said cutting blade to a predetermined depth therein, such that the hole remains forwardly disposed from said handle portion.

A device for cutting, comprising:

• a cutting blade formed of metal and having a forwardly disposed toothed portion and a rearwardly disposed tapered shank portion;
• and
• a handle portion formed of plastic material and provided with a tapered slot defined therein for accommodating said tapered shank portion of said cutting blade such that said cutting blade can be attached to said handle, said handle portion having a forwardly facing surface surrounding said slot, said slot having an enlarged forward opening, said slot being configured and positioned to accommodate said toothed portion of said cutting blade such that at least a portion of a rearward-most tooth is disposed in said enlarged forward opening and rearwardly of said forwardly facing surface.

A tool, comprising:

• a working member formed of metal and having a forwardly disposed work portion and a rearwardly disposed shank portion terminating in a rearward end surface, said shank portion being tapered in shape and having outwardly extending projections terminating at associated end portions, said projections being spaced along a longitudinal axis of the member, and said end portions having increasing distances from said longitudinal axis as the associated projections are disposed further away from the end surface of said shank portion;
• and
• a handle portion formed of plastic material and having a tapered slot defined therein for accommodating said shank portion of said working member such that said projections are fixedly secured within said handle portion.

• and
• a handle portion formed of plastic material and provided with a tapered slot defined therein for accommodating said tapered shank portion of said working member to a predetermined depth therein, such that the hole remains forwardly disposed from said handle portion, wherein said tool is a saw and said forwardly disposed work portion comprises saw teeth.

A tool, comprising:

• a working member formed of metal and having a forwardly disposed work portion and a rearwardly disposed tapered shank portion;
• and
• a handle portion formed of plastic material and provided with a tapered slot defined therein for accommodating said tapered shank portion of said working member such that said working member can be attached to said handle, said handle portion having a forwardly facing surface surrounding said slot, said slot having an enlarged forward opening, said slot being configured and positioned to accommodate said work portion of said working member such that at least a portion of the work portion is disposed in said enlarged forward opening and rearwardly of said forwardly facing surface.

A tool, comprising:

• a working member formed of metal;
• a handle portion formed of plastic material and having a tapered slot defined therein;
• a connecting portion having plural outwardly extending projections terminating at associated end portions, said projections being spaced along a longitudinal axis of the member, said end portions having increasing distances from said longitudinal axis as the associated projections approach an end of the connecting portion, said connecting portion having said end portions thereof disposed in retaining contact with the plastic material within said slot.
