About Lewis Safety Knife Co.
The Lewis Safety Knife Company is a division of the Seal-O-Matic Corporation, a family owned business established in 1933. Seal-O-Matic Corp.was one of the pioneers in the shipping and packaging industry. In 1950 we expanded into the safety market by manufacturing our first patented safety knife, the Lewis K310-3. The success of this knife led to the development of other safety tools over the years, including safety box openers, safety staple removers, safety carton reducers, and safety tape dispensers.
In 2000, we created the new, American made, patented Lewis K710 Locking Safety Knife. The knife’s automatic locking safety hood snaps shut and locks instantly when contact is lost with the cutting surface. Other features include two definitive depth of cut settings, easy blade changing and a proven ergonomic handle design that is comfortable for any size hand and can be used with either the left or right hand.
