The London Bridge terror attackers used 12in pink kitchen knives which had been bought from a Lidl supermarket weeks earlier, an inquest has heard.
Rachid Redouane, one of the three attackers, was seen on CCTV being helped by a staff member as he bought the knives at a self-checkout till.
The inquest also heard how London Bridge may have only been chosen as the target on the night.
Eight people died in the attack on 3 June 2017.
Redouane, 30, along with Khuram Butt, 27, and Youssef Zaghba, 22, mowed down pedestrians on London Bridge before launching a knife attack in nearby Borough Market, injuring 48 others.
Police shot and killed the three men less than 10 minutes after the violence began.
The inquest into the victims’ deaths is being held at London’s Old Bailey.
On Wednesday, the court was shown CCTV footage of the attackers’ movements in the days and weeks leading up to the attack.
After buying the knives from the Lidl in East Ham on 15 May, Redouane returned to the same store just over a fortnight later on 30 May and bought wine bottles, the footage showed.
The court heard that these bottles were prepared as Molotov cocktails – all filled with a flammable liquid and fitted with a wick – and were found in the attackers’ van on the night of the attack.
Meanwhile, CCTV footage from outside the gym which the three men used showed that on 2 June, the evening before the attack, Redouane threw away a phone in some rubbish before walking away to talk with the two other attackers. He returned later to retrieve his phone, and Butt and Zaghba briefly embraced.
It was suggested in court that Redouane may have been concerned that his phone could be used to monitor him.
A CCTV image also showed a phone recovered from the attackers’ van which showed directions to Oxford Street in central London.
The court heard how London Bridge may have been identified as a target only on the night of the attack as the van was driven over it twice before being turned around a final time to be driven south across the bridge and into pedestrians.

The inquest has already heard some evidence relating to the deaths of the eight victims: Xavier Thomas, 45, Christine Archibald, 30, Sara Zelenak, 21, Sebastien Belanger, 36, James McMullan, 32, Kirsty Boden, 28, Alexandre Pigeard, 26, and Ignacio Echeverria, 39.
Earlier this week, the inquest at the Old Bailey heard that a relative of Butt had reported him to an anti-terror hotline two years before the attack.
The court heard how Butt had been an “earnest and hard-working” schoolboy. In his early 20s he was a “normal guy” who liked football and music and smoked cannabis, friends and colleagues said.
However, in around 2013, he began showing signs of extremism and two years later his family became concerned that he wanted to travel to Syria.
