Modified Blade

Abstract

A modified blade or knife that fits into a utility knife for cutting metal, wood, carpet and other materials. The blade or knife uses the utility knife body as a handle for easy, quick changing of multiple cutting edges to handle jobs that require a small tool in tight spaces without the need for power. The blades come in many common styles, fine tooth for metal, rough teeth for wood and sharp rounded blades for materials like carpet.

Claims

1. A modified reciprocating saw blade with said modified end clips into the body of a common utility knife body with at least one cutting edge with defined teeth.

2. A modified reciprocating saw blade with said modified end clips into the body of a common utility knife body with at least one cutting edge

3. A filing blade for filing materials incorporating the said modified end to clip into the body of a utility knife using the method of the present invention.

4. A double edge reciprocating saw blade with said modified end clips into the body of a common utility knife body on one end and the common reciprocating blade attachment on the other end for use in either tool.

5. Utility knife attachments with the modified end for the means to scrape or file using the present invention to clip into a utility knife body

Description

Description of the Preferred Embodiment

[0004] 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 FIGS. 1-5 Additional features and/or advantages of the invention will become apparent from the ensuing description or may be learned by practicing the invention. In the figures the drawings are not to scale with like numerals referring to like features throughout both the drawings and the description. Referring now to FIGS. 1-5 there is generally illustrated a reciprocating saw blade modified 1, 2 to accept a utility knife body 12 as a handle in several designs 3,4,5,6 showing the various methods blades can be manufactured to cut various materials. As the drawings of the present invention do not depict all of the possible attachments to the utility knife, drawings are shown for reference to different styles of blades 3,4,5,6 to understand and learn the present invention. While fine tooth blades and rough tooth blades are common cutting blades that can be attached to the utility knife body 12 using the present invention, other cutting knives 6 can be made to clip into the utility knife body using the present invention as well as a blade 13 made to file down material. Because the present invention uses a reciprocating style blade, adding the existing reciprocating style 7 to the opposing end of the present invention 8, 9 to attach the present invention to a utility knife body or electric reciprocating saw could be useful with teeth on both sides 10, 11 or just 10 or 11

DESCRIPTION OF RELATED ART

[0005] 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.
