Abstract
A cylindrical sleeve has a conically tapered end from which three spring members extend. Additionally, within the sleeve is a shaft that has a portion which extends from the tapered end. The extending portion includes an end of the shaft in the shape of a right truncated cone. The spring members, the extending portion and the tapered end are all inserted within a hollow cylindrical blade that has a cutting edge at its distal end. An edge of the proximal end of the blade is maintained in contact with the tapered end by adjusting the length of the extending portion to cause the extending portion to push the spring members against the interior surface of the blade.
