Joshua Ribera was stabbed near a nightclub in Selly Oak in September
A campaign urging people to hand in knives has been launched in Birmingham.
Families of stab victims helped unveil a knife bin at The Hub in Holford Drive, Perry Barr, as part of the "Save A Life Surrender A Knife" initiative.
Another knife bin is due to be opened in Sparkbrook next week while Aston will get one next month.
The British Ironworks Centre in Oswestry plans to use the knives to create a monument commemorating the lives of stabbing victims.
Kathleen Harris, the mother of 16-year-old Christina Edkins, who was killed on a bus in Birmingham last year, joined other families in Perry Barr, the first of 150 knife bins due to be set up around the country.
Recent Birmingham knife victims also include musician Joshua Ribera, who was stabbed through the heart in September and his friend 16-year-old Kyle Sheehan, who was killed almost exactly a year earlier.
A total of 16 knives were handed in during a three-month knife surrender earlier this year.
