Provided are an apparatus and method for cutting a glass laminate The apparatus comprises a first and second part spaced apart from each other by a first gap, a first guide block and a second guide block spaced apart from each other by a second gap, wherein a saw blade is able to pass through first and second gaps, a first fixing unit and second fixing unit, each capable of fixing the respective first guide block and second guide block to the respective first part and second part of the table, and thus defining a space for a glass laminate.

A method of cutting a glass sheet is disclosed. The method comprises heating a heating element to a heat temperature, which in turn heats a glass sheet along a desired cutting line, to a separation temperature. The glass sheet is subjected to non-destructive pressure at an edge on the cutting line. The non-destructive pressure may be applied by a tool with opposed sharp edges so long as the edges do not nick or otherwise score the glass sheet. A diagonal cutter may be utilized as the sharp-edged tool. After an adequate amount of heating time, the glass sheet will achieve the separation temperature and spontaneously separate along the heated cutting line.

An arcuate or circular cutting and/or marking apparatus comprises a bridging element comprising legs engageable to a grid base, wherein the bridging element comprises a circular cutting and/or marking element extending from a bottom of the bridging element for cutting and/or marking material, and a rotary handle connected to the circular cutting and/or marking element extending from a top of the bridging element for rotating the cutting and/or marking element. Systems and methods of the same are further provided.

A method of separating an edge strip of a sheet of brittle material using a handheld sheet edge strip separation device is provided. The method includes sliding an edge receiving channel of a separation body of the sheet edge strip separation device over an edge portion that includes an edge of the sheet of brittle material. The edge receiving channel has a fixed width and is integrally formed as part of the separation body. The sheet edge strip separation device is rotated to provide a force over an area of the edge portion. The edge strip is separated from a quality portion of the sheet of brittle material with the glass edge strip located in the edge receiving channel.
