Fuller open way is a notable classification within the product category of knives and multi-tools, defined by its distinctive design and versatile functionality. The fuller, often referred to as a “blood groove,” is a long, narrow, and shallow groove or channel that is precisely machined or forged into the blade’s surface. Contrary to its name, it does not actually hold blood but serves a variety of practical purposes. One of the key advantages of a fuller is its ability to reduce the overall weight of the blade without compromising structural integrity. Additionally, it can enhance blade stiffness and balance. Shieldon has been instrumental in providing fuller open way solutions to clients. Our OEM/ODM mastery in crafting precision tools ensures that clients receive superior products with fullers that are not only functional but also aesthetically pleasing, enhancing both the usability and market appeal of their knives and multi-tools.
