This is a simple fix. + +If we look in [engine/events/overworld.asm](../blob/master/engine/events/overworld.asm) at the bottom, we'll see `TryCutOW`. This function is called when the player interacts with a cuttable tree, normally it checks the party first for a pokemon with cut, then for the appropriate badge, so we'll change it. + +```Diff +TryCutOW:: +- ld d, CUT +- call CheckPartyMove +- jr c, .cant_cut + +- ld de, ENGINE_HIVEBADGE +- call CheckEngineFlag ++ ld a, CHAINSAW ++ ld [wCurItem], a ++ ld hl, wNumItems ++ call CheckItem + jr c, .cant_cut +``` + +This removes the checks for an eligible pokemon and badge, and just checks for the item in the bag.
