By searching the new IWD files that came with the map pack i found out:
Sickle:Code:bind XX "give bh_bomb_zm"
Matrioshka doll(i am not sure about this because there are a code with each of the carachters names but i suppose this is the name):Code:bind XX "give sicke_zm"
NOTE: I have not tested this. It is purely based on the file names i found in iw_26.iwdCode:bind XX "give nesting_bomb_zm"
