Tungsten needles with sharper tips generally have a better ability to penetrate tissue compared to needles with duller tips. This is because a sharper tip creates a smaller area of initial tissue damage, which can reduce the force required for insertion and potentially reduce tissue trauma. Additionally, a sharper tip can also help to reduce the risk of needle deflection during insertion, which can be important for precision procedures. However, the optimal tip sharpness may depend on the specific application and tissue type being targeted, as different tissues may require different needle geometries for optimal performance.
