A mandrel (300) for holding an intraocular lens blank (200) during manufacturing includes an intraocular lens holding section configured to hold an intraocular lens, the intraocular lens holding section including: a central cavity (310) configured to hold a mounting material (315) such that the mounting material contacts an optic of the intraocular lens blank when the intraocular lens blank is mounted on the mandrel, and a projection (325) extending around a periphery of the central cavity, the projection having an outer wall (330) and an inner wall (335), and the projection being configured such that an outer peripheral edge of the intraocular lens blank extends up to or beyond the projection when the intraocular lens blank is mounted on the mandrel. A second mounting material (320) is deposited in the first trench (340) and then the haptic is milled using e.g. an end mill (365).

A blocking tool and a method of using the blocking tool to sand a surface of a vehicle are disclosed. The blocking tool includes a first member having a length and having an outer periphery with a plurality of cuts formed therein. The plurality of cuts extend over at least about 70% of the length and each of the cuts penetrates the first member through an arc of at least about 70% of the outer periphery. The blocking tool also has a base member with a first surface, an oppositely aligned second surface, and a length. A portion of the outer periphery of the first member is secured to the first surface of the base member to form an integral blocking tool.
