Can anyone confirm if it is fine to use the hammer end of my Estwing Geological pick for striking a small cold chisel when fossil hunting - or is it just for striking rocks/ It actually stipulates that the pick end is for prying only (which is fine) but the that hammer end is only for wooden stakes! Is this an overkill by Estwing to manage their H&S liability or is it common knowledge that you canuse the hammer on cold chisels? Any advice gratefully appreciated! Cheers - Rick
