To most, the presence of a cutting guide can help reduce the risk of accidents or injuries by providing a stable surface for the blade to glide along, rather than relying on your hand to guide the knife. It also actively prevents the blade from slipping. Adult people with vision impairment between 1/20 and 4/10 (defined as mild to medium visual acuity reduction by the French Ophthalmology Association) will find the use of the Precision Slicing Knife suited for their condition and helpful to their daily activities in the kitchen. For people with vision loss, the serrated blade makes it safer to determine the location of the cutting edge without visual cues, and the metal guide serves as a reliable measure to achieve consistent thickness regardless of dexterity confidence, warranting both thick or thin constant slicing and greatly reducing risks of inadvertent slippage. The hexagonal screw is easy and safe to handle as the user slides the guide on the rails to the desired thickness even before starting to cut.
It is simply an easy-to-use and accessible tool that will find itself indispensable in many kitchens, including those of visually handicapped persons.
