Effective 10th March 2009: eBay prohibits members from listing knives on eBay.co.uk and eBay.ie with one exception:
Cutlery: this includes sets of kitchen cutlery (knives, forks, spoons) that contain knives used for eating, but does not include sharp kitchen knives such as those found in knife blocks, such as paring knives.
Members should be aware when listing knives on eBay that it is an offence to market a knife in a way which indicates or suggests that it is suitable for combat, or is likely to encourage violent behaviour involving the use of the knife as a weapon. It is also an offence to sell knives to a person who is under the age of 18.
What is this??!!! Pretty silly rule in my opinion... any UK reader's check out this site...
