It sits between the single-point needle and the flat serrated head: the points still concentrate enough load to cut through oxide and flux, but because there are several of them the probe is far less likely to skate off a slightly domed or uneven target, and a failed contact on one point does not lose the measurement. That makes it a good default on reflowed pads and through-hole joints.
