McPherson-Vannas Micro Dissecting Spring Scissors; Straight, Sharp Needle Points; 3mm Cutting Edge; 0.1mm Tip Width; 3" Overall Length
 

These fine micro dissecting scissors have very thin blades with long taper and sharp needle points.  The thin blades are ideal for working in narrow spaces like when reaching inside blood vessels to cut their walls.

These scissors are also the best option for working under microscopes as they are less bulky than other designs thus they are less likely to obstruct the view.
