Methods and apparatuses for fabricating a needle assembly which includes a blunt in a cannula of a needle. In one example of a method, at least one blunt is collected in a cutout of a blade from a set of blunts and a fluid is passed across said cutout. Any further blunts around the cutout are dislodged by the fluid, leaving only one blunt on the blade. In another example of a method, a blade is moved to a first position to collect at least one blunt from a set of blunts, and the blade is moved to a second position to singulate the one blunt from the set of blunts; the blade has a tip end which is designed to capture securely only one blunt, wherein any further blunts are not securely maintained in the tip end. An exemplary apparatus includes a container for holding a set of blunts, a motor, and a blade coupled to the motor and disposed at least partially within a slot of said container. The blade includes a tip end which is designed to capture securely only one blunt.
