Price and rating as shown on Amazon when we collected them. Both change.
This is the Diamond Edge No.1 in ruby red, at the same £12.99 with the same 10,515 ratings as the black version at number four.
It takes fifth because the tool and price are identical, while the two listings disagree about its weight by ten grams and describe the same cube in two different dimension orders.
