You don't buy weapons you buy antiques that just happen to be weapons, they are exempt and they are always better made and hold thier value so you should be buying them in the first place. I own antique warclubs, swordsticks and once money allows it again will be buying a really nice katana again.

I saw a Japanese weapon that was made illegal here recently that looks almost the same as my rice knife but with a flat blade. Persumably my gardening rice knife is still exempt?...Makes you wonder if they will be trying to outlaw a pointed stick or a broken glass bottle before addressing the social issues they have in certain London neighbourhoods.
