Claim:
A method for sharpening the tip of a microprobe, the method comprising the steps of: providing at least one probe, each probe of said at least one probe having a base portion, an elongate shaft portion and a triangular chisel-shaped tip portion, at least said shaft and tip portions having an essentially constant thickness extending between a first and second surface of the probe; providing a carrier having a first and second flat outer surface oriented at an angle to each other, so that said surfaces are joined by an edge of said carrier; and for each probe of said at least one probe, (i) attaching the first surface of the probe to the second surface of the carrier, with the base portion and the majority of the shaft portion attached to said second surface and the tip portion being in close proximity to said edge; and (ii) subjecting the first surface of the carrier and at least part of the tip portion of the probe to a grinding step, to thereby remove material at least from said triangular, chisel shaped tip portion of the probe, wherein at least part of said triangular, chisel shaped tip portion is extending outward from said edge, so that said part of the triangular tip portion extends below the first surface of the carrier when said first surface is held horizontally, and wherein substantially no material of the carrier is removed during said grinding step.
