I would like to be able to buy, and sell, and evolve the collection of my knives, which range from little pen knives, to Hunting Knives, Antique Military swords to practical everyday tools. Collectors break no laws in owning these items, so I see no reason Ebay do not allow the trade in such items. Knives are widely available in the highstreet, such as kitchen knives, what is hard to find are the rare old works of art so many people love to collect. I have never been told of any reason why we can't buy knives on Ebay.
