This illegal flick-knife is almost identical to the one used to kill tragic Yousef Makki and cost us just £10 online with no age checks.

Shockingly, it was also ordered on the same website as the blade that ended the 17-year-old grammar school pupil’s life – just hours after his killer was sentenced this week.

A Sunday Mirror probe found the lethal weapons are available on Wish within just three clicks on a mobile phone.

Former Met Police inspector Peter Kirkham said: “This is despicable. These companies are profiting from the knife crime epidemic.

“If you buy these in a shop, like alcohol, checks would be made. It would be mandatory.

“If sites can’t ask for ID and sell responsibly, we should block them. Something drastic has to happen. Too many are dying.”

Yousef died after a boy of 17, known as Boy A, stabbed him in the heart in Hale Barns, Greater Manchester, on March 2.

He was cleared of murder and manslaughter but got 16 months in youth jail for perverting justice and possession of a knife.

Manchester crown court heard Boy B, 17, bought the knife on Wish. He got four months.

And hours after Thursday’s sentencing, we found our blade on Wish after a search for flick-knives – with no age checks made during the purchase.

Reviewers call the 9in knife, with a 3.7in blade, a “finely crafted weapon”.

Another on the site, the OTF Switch Blade, costs £9 plus £3 UK delivery.

It is also 9in long with a 3.7in blade and we bought both in three clicks.

It is illegal to sell a knife with a folding blade of 3in or longer to under-18s.

It is also illegal to have a knife with a blade over 3in in public or carry, buy or sell any banned knife – including flicks.

The funeral of Yousef Makki – yet knives like the one that killed the schoolboy are still readily available, cheap and with no age checks 

Wish is operated by a San Francisco firm and a spokesman said it is an “e-commerce site”, a platform between seller and buyer.They said: “It is up to customs officers in individual countries to work out what is legal and illegal.”

There have been 78 knife killings in London this year. Last year was the city’s bloodiest in 10 years with homicides hitting 132.

And figures this week showed a record 43,000 knife offences in England
