An array of knives hangs by the door of a discount store where terrorist Sudesh Amman armed himself on his rampage.
Nine types of blades are still on shelves – including a machete priced at just £4.99.
Fanatic Amman stole a £3.99 kitchen knife from the Low Price Store in Streatham High Road, South London.
He stabbed primary school teacher Monika Luftner, 51, and a man in his forties before being shot dead by undercover police.
Astonishingly, one week on, the store is still flogging blades within easy reach.
The Sunday Mirror also found a meat cleaver on display by the counter at under £10.
All knives are legal to sell and labelled with a sign telling customers they need ID to prove they are 25 or over.
But there was no security present in the bargain store, which is run by two brothers.
Shadow Policing and Crime Minister Louise Haigh said: “It is galling to see knives still on open display in this store, but sadly this all too familiar.
“Knives are much too easy to access in stores.
"I desperately wish the Government had listened to Labour’s proposal to ban the open sale of knives, which could have helped prevent a small number of sickening attacks like this one.
“The Government should now urgently think again.”
Jamie Hoult, director of Anti-Knife UK, was “shocked and outraged” by the ease with which Amman armed himself.
Mr Hoult wants shops to keep knives in cabinets or with security features to stop customers removing them.
He said: “We need laws in place. Too many knife incidents are happening across the country.”
Anti-knife crime campaigner Sarah Armstrong, 32, who was stabbed near Streatham 13 years ago, said: “Why would they still be by the door? You’d think someone would have thought twice and moved them. It is just ridiculous, really infuriating.”
Amman, 21, was on early release after serving half of a sentence for possessing and distributing terrorist documents. He walked into Low Price Store, grabbed the blade then lashed out.
The Government is seeking legislation to block terrorists from automatic early release.
Low Price Store did not wish to comment.
