　　Subject:Prototype of ORIENT Cutting Tool

　　We have delivered the prototype of a new cutting tool for your inspection.The tool,designated as ORIENT,has been developed by the Second Group.

　　The tool is composed of four parts cast from low-carbon steel and finely machined.The cutting edges on one side of each of the two long pieces feature a bonded tungsten alloy ground to a high degree of sharpness.

　　A strong machine screw holds the two long pieces together.A tension plate of spring steel between them keeps constant pressure on the cutting edges as they are opened and closed by thumb finger action.

　　When using the tool,place the thumb in the smaller hole and the index and middle fingers in the larger one.By applying pressure with the thumb and fingers,you can easily open and close the cutting edges.

　　In a word,it is an ideal tool with few weaknesses.So we recommend it to you.
