Combat/survival knives and sword laws?

i just wanted to know what the laws are on knives and swords......as collectables in my home. they will be kept in my bedroom which has a padlock on the door, and will not be taken out. i dont have them on display shelves but the only time i touch them is to dust under them, even though there very sharp i do no intend to use them for any other reason than to admire them. is it legal to keep them in my home.....and yes, im over the age of 18 and i dont have any illegal weapons such as flick knives, butterfly knives or gravity knives. just stuff like bowie knives....things that look similar to the rambo survival knife
