Hi Fernando
,
Not another piece of rusty old metal
I believe that 'heavy' lances tended to have a diameter of 1.5" - 2" (28mm -50mm) with this having a diameter of 40mm it is well within range. Therefore it would seem to be too 'heavy duty' for hunting. Also many hunting spears/lances had two projections behind the 'head' to prevent spearing the animal too deeply and allowed the user to 'push / hold' the prey (especially wild boars/pigs that had a fearsome reputation.)
I am certain early versions of head did not all have 'protective langets'. The lance was later adopted by foot soldiers, but the shafts lenghened (Pikes) these were prevalent during the 15th, 16th and 17th C and were highly effective. Because of the increased length ..the shaft diameter was also quite thick to prevent 'flexing'. As many pike men were 'enlisted' peasants .... many pike heads were made by 'local blacksmiths' and designs varied slightly. The re-inforced blade would be ideal against a cavalry charge and it would be extremely difficult for a horseman to cut off the head with a sword whilst riding at any speed .....plus it would be likely the cavalry would charge with lances.

PS The shafts of lances of the period were usuall made of ash, though cedar and poplar are also mentioned, the shaft of yours does look like ash ...
