The main differences between the 1801 and 1889 spear bayonet is that the 1889 is weighted to counteract the weight of the stock and the 1889 is attached like the 1878 sword bayonet while the 1801 is tied to the barrel, it’s usually just held. Both are anti-cavalry weapons, they’re not useful for much else.
