The present invention relates generally to the field of cutting tools and more particularly hand cutting tools where the need for sharp cutting edges can be applied to a common utility knife and can be changed with speed and ease. The knife or blade has the appearance of a reciprocating blade but the back end has the appearance of a common utility blade which clips in to the utility knife body making the utility knife into a hand saw capable of cutting, wood metal and other materials a general a utility knife can't cut.
The Modified Cutting Blade of the present invention overcomes the deficiencies of prior art in the field by incorporating a commonly used tool, the utility knife body as a handle for a saw blade or other attachments whereas prior art in the field requires a separate handle specifically designed to hold a specific blade manufactured by a specific company. While utility knives are useful for certain jobs like cutting cardboard and other thin materials, adding a feature for cutting metal, wood, carpet, branches and other thicker, tougher materials turns the utility knife body into a handle for cutting just about anything. As will be discussed herein, the blades can be designed with tine teeth, serrated, smooth and rough teeth for cutting different materials common utility blades won't cut.
Certain embodiments of the present invention include but are not limited to will be described in detail with reference to the modified blade, as generally illustrated in
On construction jobs there is many times where electric reciprocating saws can't fit in small spaces, making using electric tools difficult and sometimes impossible to use. These saws also have cutting blades for metal and wood, ranging from fine teeth to rough, using electricity to cut materials rapidly. While electricity usually makes using power tools fast and effective, power outages sometimes occur, making these tools become useless and hand tools a must. Currently in the hand tool consumer market, saws like a the hack saw for cutting metal require a hoop like handle to accept a fine blade which commonly break and are hard to get into small spaces. Some smaller metal cutting adapted blades have handles specifically designed for that blade and require the user to buy a tool with limited uses. For instance, a carpet knife typically has a wooden handle and an attached blade with a lifespan of the blade, after the blade is worn; the handle being attached to the blade, the entire tool is discarded. Utility knives currently on the market have quick change features making it easy to change the common utility knife blade with ease and speed. The utility knife is used by tradesmen and the general public for small jobs as well as large but currently there is nothing available to the consumer to attach to the utility knife body that is capable of cutting wood, metal or other materials where a saw like blade is needed. What is needed therefore is a blade with saw like properties that is capable of clipping into the common utility knife. The blade would be configured so as to look like a reciprocating saw blade but replace the common utility knife blade when needed. Most consumers will or already have purchased a utility knife capable of holding the present invention without having to require purchasing an additional handle to secure a specific saw blade or carry an additional tool while at work.
