UK UK - Penny Bell, 43, Ealing, London, 6 June 1991

[Professor Moriarty]

I'm possibly clutching at straws, but could gloves have protected the killer's hand if he used a non lock blade?

I don't think a non-locking pocket knife would have been suitable. If you are using force to stab that many times the blade would keep shutting and, wearing gloves, you would have difficulty opening it again each time.

Some of the bigger (and illegal to carry) Swiss Army knives had buttons to lock the blade.

Penny was stabbed with a four inch blade, which seems about the right size for a large Swiss Army knife.. or a small locking knife, or small kitchen knife...

Yes. The bigger Swiss Army Knives. (The blade locks automatically on opening; the button is to release the blade for closing.) Locking knives are illegal to carry, but many only have that locking blade (ie they don't have bottle openers, scissors etc) and so are quite slim.

Although flick knives have been illegal for years, there are many in circulation. Airport security sometimes pick them up in the luggage of people returning from overseas. Some must get through.
