Help identify lance knife and bill hook

[George44]

        Hello! I have been trying to find the same type of the knife i found. So far i have identified roman boar hunting spear which is massive 735 grams, and 40 cm long. Knife and billhook are 390 grams each. Knife has a ring on pic that was probably holding the wooden handle. At same place they were all found together with a ceramic pot and a bronze key ring and 4 bronze buttons of roman military style. I believe it is a roman soldier grave. Maybe there are more around? I do not know much about roman military graves. This was found on my property and i am not sure if i should bring it to conservatorium or they gonna laugh at me. I have also found some other roman artifacts and coins around the same place Vespasian and Salonina. Please help to identify those weapons/ tools!
