20100011594 | Composite Saw Blades - Saw blades, including band saw blades, reciprocating saw blades, hole saw blades and hand hack saw blades, are made from a bi-metal strip. The bi-metal strip includes a cutting edge defined by a plurality of cutting teeth that is welded to an axially-elongated carbon or spring steel backing. The cutting edge is formed of a high speed steel alloy consisting essentially of: about 8/10% to about 1% carbon, up to about 45/100% silicon, up to about 4/10% manganese, up to about 3/100% phosphorous, up to about 3/100% sulfur, about 4% to about 6% cobalt, about 3% to about 5% chromium, about 4½% to about 5½% molybdenum, about 1% to about 2½% vanadium, about 5½% to about 7% tungsten, and about 74% to about 78½% iron. | 01-21-2010 |
20100050445 | Structure of cutting edge of diamond blade - An improved structure of a cutting edge of a diamond blade allows the cutting edge to be constantly sharp for cutting and have a long service life. The cutting edge is formed at an appropriate part of a particularly shaped metal shank or blank and is corrugated by stamping so as to form recesses on two sides of the cutting edge. The recesses of the cutting edge have inner bottoms whose depths are one-half or more than one-half a thickness of the metal shank or blank. The cutting edge can be further formed with plural openings. In addition, the two sides of the cutting edge have outer surfaces electroplated or coated with diamond particles, wherein a vertical distance between outermost portions of layers of the diamond particles formed respectively on the two sides of the cutting edge is greater than a thickness of the cutting edge. | 03-04-2010 |
20110000093 | Kitchen tool construction - A kitchen tool or implement construction comprises a composite glass fiber reinforced polyamide material, preferably “Nylon 6.6”, and may be used for making kitchen implements such as flour sieving implements, ladles, large spoons, mixing spatulas, whisks, smooth and perforated vanes, skimmers, bread, salad, spaghetti, sweet, sugar springs and grippers. | 01-06-2011 |
20110056083 | Degradable string for string trimmer - A string for string trimmer has a non-circular cross section and is made of degradable material such as Polylactide (PLA), Polycaprolactone (PCL) or Polyvinyl Acetate (PVA). The string is a spiral string with multiple cutting edges spirally extending along a longitudinal axis of the string. | 03-10-2011 |
20110232108 | CUTTING INSTRUMENT - A cutting instrument ( | 09-29-2011 |
20120222318 | EXTENDABLE UTENSIL AND METHOD OF MANUFACTURE - An extendable utensil comprises a base part and a body formed from sheet material having a first surface and a second and surface, wherein the body is arranged in a wrap around the base part in successive turns, and a point on the first surface at an end of a turn is fixed to a point on the second surface at a beginning of the turn. A method of manufacturing an extendable utensil is also disclosed. | 09-06-2012 |
20130247387 | Disposable, Single-Use Utensils for Children - A disposable, single-use utensil type is provided for use by children and child caregivers while traveling or otherwise away from home, wherein a spoon, knife, and fork are disclosed having features suitable for use by young children and a construction that is disposable after one use. The utensils include rounded edges and wide handles suitable for use by children, while the structure of the utensils is one that is disposable or recyclable after use. The utensils are packaged in sets and distributed as packs of disposable travel utensils, where further a travel pack is provided for storing a plurality of utensils during an outing and thereafter disposing of the utensils once in contact with food items and a child's mouth. The goal is to eliminate the need for parents to travel with permanent utensils, which become messy and are not easily stored after use. | 09-26-2013 |
20130247388 | CERAMIC CUTTING KNIFE AND METHOD FOR MANUFACTURING SAME - A ceramic knife and a method for producing the ceramic knife are disclosed. The ceramic knife includes a base member and two layers on the base member. The base member includes zirconia as a main component. The base member further includes a cutting edge and a cutting edge portion that is adjacent area of the cutting edge. Two layers include a first layer and a second layer. The first layer is located at least on the cutting edge portion of the base member, and includes nitride material such as zirconium nitride, silicon nitride and aluminum nitride. The second layer is located on the first layer, and includes diamond-like carbon or DLS. | 09-26-2013 |
20140082947 | METHOD FOR CREATING ATOMICALLY SHARP EDGES ON OBJECTS MADE OF CRYSTAL MATERIAL - A process to make atomically sharp cutting devices is described. The process may provide for a cost effective and efficient technique of producing the atomically sharp cutting devices made from single crystal material such as, for example, sapphire, silicon carbide, silicon, and the like. The process may include identifying and choosing a preferred geometric orientation of the crystal material where cleavage can be promoted along a preferred natural plane of the single crystal material, thus ultimately producing an atomically sharp edge. The single crystal material may be covered at select surface locations by a photo-resist material arranged in a predetermined alignment with reference to the preferred plane to prevent etching at unexposed surface portions while permitting etching at exposed surface portions of the single crystal material. An atomic edge may be created by physical cleaving once the etching has reached a predetermined end-point. | 03-27-2014 |
20140157606 | Lightweight Knife - The present invention relates to a lightweight knife. Conventional knives are made of steel and other heavy materials. While metal knives provide excellent strength and cutting ability, they can be heavy, which adds weight to an individual's load, pack, kit, or supplies on their person. Previous attempts to produce a lightweight knife have focused on replacing steel with lightweight materials. Plastic knives are light and have been produced, but do not provide an effective, sharp cutting edge. The present invention uses plastic insertion molding technology to imbed a partial steel blade in an otherwise plastic knife, significantly reducing overall weight while still providing a strong, effective cutting edge. | 06-12-2014 |
