Courts are giving out tougher sentences for knife possession
The number of knife deaths in areas targeted by an anti-knife crime scheme has risen, the Home Office has said.
The government's Tackling Knives Action Programme started last July in 10 police areas in England and Wales.
In its first nine months, 126 people died after being attacked with a knife or other sharp object - seven more than in the same period the previous year.
Overall knife-related violence fell by 10%, but the number of deaths among teenagers remains unchanged.
The Home Office-led Tackling Knives Action Programme (TKAP) was triggered by a series of high-profile teenage stabbings.
Police have stepped up searches and patrols in knife crime hotspots and are running courses to highlight the dangers of carrying the weapons.
Home Secretary Alan Johnson: "It is disappointing"
A second phase of the scheme, focusing on all forms of serious violence among 13 to 24-year-olds, will now be rolled out. About £5m will be made available to the 10 original forces and six others.
Warwickshire Chief Constable Keith Bristow, who leads TKAP, said "public angst" over knife crime was understandable but added that there were some "promising signs" in the reduction of killings among youngsters.
He said: "It's a mixed picture in the sense that in some places there have been some increases but overall it's going in the right direction.
"This is a long journey. Success when you're dealing with these sort of problems might be measured in generations, not weeks or months."
The figures also showed the number of offenders aged 19 and under possessing an offensive weapon fell 13% despite an increase in stop and search measures in all 10 police force areas.
Robberies with sharp instruments against those aged 19 and under also fell by 13%. According to provisional figures knife-related hospital admissions fell 32%, compared with 18% in non-TKAP areas.
