Hi, Polly.
I just dont have a photo with me, in the plant, in areas where there is low frequency of opening of packaging, what was used are scissors. In areas with large frequency of packaging opening, what was used was fabricated knife. This is made from one solid stainless steel structure with the approximate dimension.
length is around 5 inches, thickness is around 1 cm, one end is tapered for safety purposes and one end is fitted with a ring for easy handling.
The length is divided into 3 inches for the handle and the remaining 2 inch as the cutting part itself ( the 2 inch part is constructed like what you see in ax blade).
The design can be easily be cleaned, no movable part, durable due its thickness and no hollow bodies where dirt may accumulate. In addition, frequency can be established to sharpened the blade removing the cost for blade replacement.
