Pretty sure Lances could do either impact or cutting in early games, depending on the weakness of the hitzone you were attacking (unless it was a tail, then it was always cutting). This was then rectified somepoint during the 3rd Generation, and now they only do Cutting damage.

I might be wrong with some of that.
