Final answer:
The safest way to attach a blade to a knife handle involves using specialized tools and safety equipment while fitting the blade securely into the handle. Designs with multiple blades, such as a three-blade knife, may also enhance safety and efficiency.
Step-by-step explanation:
The safest method for placing a blade on a knife handle is with the use of specialized tools and safety equipment, such as blade tongs or a vice, and protective gloves. This procedure should be conducted carefully to ensure that the blade is securely attached and the risk of injury is minimized. The process typically involves fitting the blade into the handle and then securing it, either by tightening screws or riveting, or by applying an adhesive if it’s a design where the handle is meant to be permanently attached over the blade, like in the example of a knife with an iron blade and hollow bronze handle from the 1st millennium BC. It’s also important to note that the design of the knife, including the number of blades and their tip speed, can affect the safety and efficiency of the knife, as pointed out in the reference to a three-blade design being more efficient and safer than those with fewer blades.
