IMPROVED CIGAR CUTTER
Technical Field This invention relates to the field of smoking implements; and more particularly to devices used for trimming the tip from cigars.
Background Art
In order to facilitate the lighting and smoking of cigars, it has long been found desirable to cut a small portion from the end of the cigar which is to be placed in the smoker's mouth, thereby permitting easier flow of air and eventually smoke, axially through the cigar into the smoker's mouth.
Various devices have been employed to cut the tips from cigars. These devices include pen knives, shears, and various bladed cutters. As it is desirable to have a smoothly cut cigar end to place in the mouth, efforts to trim cigar ends with pen knives and shears have been less than satisfactory.
The bladed-type cutters employed for trimming cigars include single and dual bladed "guillotine" devices, which, while effective and easy to use when new soon become dull and difficult to use. While other more sophisticated cutters have been devised, some of them have been complex in construction and operation as well as difficult and expensive to manufacture, thereby limiting their sales appeal.
Safety is also a concern for a cigar trimmer. As sharp blades are typically involved, it is important that the blades be retained in a safe position before and after use of the cutter and that provisions be made to prevent possible injury during use of the device.
