Demolition tools are presented including: a handle having a proximal end and a distal end; a prying head disposed along the distal end of the handle, the prying head including at least two tines mechanically coupled with a substantially cylindrical cross frame, where the at least two tines each includes: an upper surface forming a width, a proximal end and a distal end; a tapered base including a first end forming a profile complementary to the substantially cylindrical cross frame, the tapered base mechanically coupled to the cylindrical cross frame at the proximal end of the upper surface along the profile, the tapered base tapering upward towards the upper surface from the first end towards the distal end of the upper surface, where the at least two tines each form a fulcrum point where the tapered base is coupled with the cross frame.

A striking hand tool includes a grip component where an external surface has a front arc half and a rear arc half, wherein an area of the grip is smaller in a first cross sectional plane further from a head of the tool than a second plane closer to the head portion. A ρ value of the front arc half in the first cross sectional plane is less than approximately 0.45. A measurement from a first axis to a frontmost point in the first cross sectional plane is between 17.5 mm and 19 mm. A ρ value of the front arc half in the second cross sectional plane is less than approximately 0.5. A measurement from the first axis to a frontmost point in the second cross sectional plane is between 18.5 mm and 20 mm. Methods of manufacturing and striking hand tools having desirous durometer measurements are also disclosed.

A system includes a universal handle and a variety of tools selectively secured within the handle. The tools can be tools for grooming or collecting hair, and are especially useful with animals such as household pets. One example tool includes a mat breaker that is adjustable for left handed or right handed use. Another example tool is a fur sweeper tool and a fur accumulator tool. Other tools include deshedders, brushes, and combs.

A knife has a handle that is fastened to the knife blade and that has a first recess that opens towards the handle end and is closed by an end cap or end disc which lies in or abuts on the recess. The rear side of the end cap/end disc has at least two tongues molded thereon parallel to the longitudinal axis of the handle and which project into a longitudinal recess which starts from the first recess and projects inwardly in the direction of the knife blade. The inner wall of the longitudinal recess has longitudinal ribs that are parallel to the longitudinal axis of the handle and jut out from opposite wall sides. The free ends of the tongues have on their outer side at least one tooth or a tooth strip which being forced into the longitudinal rib is/are held therein.

A knife and associated guide for the cutting of fibrous batt insulation products, as well as rigid foam board insulation products are described. The knife has a handle and blade, each oriented so as to maximize the ability to pull the blade through the material to be cut, while minimizing the muscular effort and strain required of the user. The guide is configured to easily compress batt insulation products and to be easily moved over the products for improved efficiency.

Certain embodiments are directed to a laryngoscopy device and methods of use thereof, the device having a curved, hollow stylet with a handle and a flexible bougie contained at least partially within the hollow stylet, the bougie being extendable out of the end of the stylet for use in guidance of a hollow endotracheal tube.
