Abstract
The present disclosure provides cutting tools which include a handle coupled to a rotatable shaft having shallow grooves that extend substantially entirely across the surface of the rotatable shaft. The grooves define sharp cutting edges. In particular examples, the cutting edges are continuous, such as being defined by helical threads. The present disclosure also provides methods of dissecting a substrate of cultured cells. The substrate of cultured cells is separated into separated portions with a cutting tool. The cutting tool includes a rotatable shaft having a cutting blade which extends around the shaft. The cutting blade is rolled through the substrate to cut the substrate into portions. The portions are separated from one another to dissect the substrate.
Claims16
A cutting device for dissecting a substrate of cultured cells comprising:
- (A) a handle, and
- (B) a rotatable shaft coupled to the handle for rotation about a rolling axis wherein shallow grooves in the surface of the rotatable shaft define sharp cutting edges that extend substantially entirely across the surface of the rotatable shaft,
- wherein the shallow grooves comprise a continuous groove in a surface of the rotatable shaft with the sharp cutting edges extending upward on both sides of the continuous groove into sharp crests that define a continuous cutting surface that extends substantially entirely across the surface of the rotatable shaft.
