The authors have presented an interesting review of the use of fall cones to determine Atterberg limits (O’Kelly et al., 2018). Wood (1983: p. 80) recognised that the fall-cone test was not suited to determine the true plastic limit (PL): ‘It is not clear how the cone penetrometer plastic limit gives an indication of the water content at which soil changes from the brittle to the plastic state’. The discusser wishes to comment on the strength–water content relationship and the plastic strength limit (PSL, an acronym that is preferable to PL to reinforce that this is a strength-based value with no relation to the true plastic limit)
