A foot rest for a post-hole digger and post-hole diggers using the foot rest are disclosed. The foot rest includes two portions, one attached to each shaft of the post-hole digger. The two portions have structure that allows them to engage one another when the two shafts of the post-hole digger are vertical. The foot rest does not extend beyond the bore diameter of the post-hole digger. Thus, in order to keep the user's feet on the relatively short foot rest, the contact surface of the foot rest may be angled. In some embodiments, the foot rest may be symmetrical, so that either side may be used as the upper surface. A post-hole digger including the foot rests typically includes at least two foot rests, spaced from one another and facing different directions along the shafts of the tool.

A fluid shovel apparatus that pushes and lifts loose material such as snow, leaves, sand, dirt, grass clippings, mulch, or the like. The present invention includes at least one fluid exhaust port extending through a blade. Pressurized fluid is ejected through the at least one fluid exhaust port extending through the blade and ejects towards loose material. The loose material floats on a cushion of pressurized fluid that forms between the blade and the loose material. The loose material is pushed away from the blade and is lifted in an upward direction. Additionally, the fluid shovel apparatus may further include a soft pad and an ice scraper blade to assist in removing material from a surface of a motor vehicle. Additionally, the fluid shovel apparatus may be used to deliver a fire suppressant pressurized fluid upon a material that is burning. Additionally, the fluid shovel apparatus may be used to clear snow from railroad train tracks ahead of a railroad train car.

The present disclosure relates to a shovel assembly for use in association with snow, sand, or any other particulate matter for collection and cleaning residing on a flat horizontal surface such as the ground, more specifically the shovel assembly and a method of assembly and use thereof in which the shovel's blade is made of multiple interlocked sections, each having opposite top and bottom edges with different geometries adapted for different purposes, an adjustable composite handle with multiple grips for adaptation to varied user preferences and a dynamic pivot at the base of the handle to easily change the blade's push angle during use.

The invention provides a shovel for chemical production. The shovel for chemical production comprises a shovel body and a handle, wherein the handle is fixedly connected with the shovel body; a supporting leg is arranged below the handle and is positioned at a connection position between the handle and the shovel body; the front end of the shovel body is in the shape of an arc groove; circular projections are arranged on the front surface of the shovel body; the handle is made of a transparent heat-insulation material and has a hollow structure; an LED (light emitting diode) lamp is fixedly arranged at one end, which is close to the shovel body, in the handle; a battery holder and a control switch which are electrically connected with the LED lamp are arranged on the outer wall of the other end of the handle; and a plastic sleeve layer is arranged on a handheld portion of the handle and is provided with circular anti-slipping projections.
