A saw contains: a saw blade, a handle, and an auxiliary fixing device. The saw blade includes a serrated sawing section, a connection shaft, a fixing post defined between the connection shaft and the handle. The auxiliary fixing device includes two clamp extensions, wherein two front ends of the two clamp extensions are connected together by using a guiding section of the auxiliary fixing device. The auxiliary fixing device also includes two first elastic rings respectively rolled on two rear ends of the two clamp extensions, two second elastic rings individually formed in the two first elastic rings. Each second elastic ring is eccentric with each first elastic ring and its diameter is less than that of each first elastic ring, each second elastic ring is rotatably fitted with the connection shaft, and each first elastic ring abuts against the fixing post as not using the saw.

A tamping apparatus that is configured to be operably coupled to a reciprocating saw in order to be employed to compact material. The present invention includes a stem member having a first end and a second end wherein the first end includes a tang configured to be operably coupled to a chuck of a reciprocating saw. A plate member is secured to the second end of the stem member and is planar in manner. The plate member includes a rolled front edge and in a preferred embodiment is rectangular in shape. The tamping apparatus further includes an expansion plate member that is configured to be releasably secured to the plate member and has a surface area that is larger. An impact force reduction member is integrally formed with the stem member and provides reduction of impact force transferred to the reciprocating saw during use of the tamping apparatus.

A portioning device for cutting or leveling a food product includes a blade configured to cut the food product, a first leg section and a second leg section configured to support the portioning device on a surface, and a handle section configured to be manipulated by a user. Each of the first and second leg sections include a leg, a blade holder configured to connect with the blade, and a leg lock operatively mounted to the leg and configured to selectively lock the leg in a position at a selected height of the leg to adjust a distance between the blade and the surface. The blade is a wire. The handle section is foldable about the central portion thereof to place the device in a collapsed configuration.

A portioning device is provided for use in cutting or leveling a food product. The portioning device comprises a handle section that is configured to be manipulated by a user, a leg section and a blade. The handle section includes an arm configured to receive a leg, a sleeve configured to slide over a portion of the arm, and an arm connector pivotally coupled to the arm. The leg section is configured to support the portioning device on a surface. The leg section includes a blade holder configured to hold an end of a blade portion, and a leg lock configured to adjustably lock the leg in a position. The blade is configured to cut an object.

A reciprocating tool includes a reciprocation conversion mechanism disposed in a casing neck, a saw blade connected to the reciprocation conversion mechanism, a shoe, and a shoe adjustment mechanism. The shoe adjustment mechanism has a cover plate connected to the reciprocation conversion mechanism and a slide pin. The shoe has a support and a guide plate pivotably connected to the support. The guide plate is disposed between the cover plate and the reciprocation conversion mechanism. The guide plate has a slide groove parallel to a direction of reciprocation. The slide pin passes through the slide groove. In a locked position of the shoe adjustment mechanism the slide pin is engaged in the slide groove and the guide plate is locked by the slide pin. In an unlocked position the slide pin is disengaged from the slide groove and the guide plate is slidable in the direction of reciprocation.
