Stab vest

[citation needed] Bulletproof vests are more commonly used by police in countries with greater firearms ownership, such as the United States and Canada; but dual-purpose armor plates that protect against both stab and firearms attacks are fairly widely available for police and also security applications.

[citation needed] In the mid-1980s the state of California Department of Corrections issued a requirement for a body armor using a commercial ice pick as the test penetrator.

The test method attempted to simulate the capacity of a human attacker to deliver impact energy with their upper body.

These textile materials do not have equal performance with cutting-edge threats and these certifications were only with ice picks and were not tested with knives.

The PSDB standard was replaced in 2007 with the current Home Office Scientific Development Branch (HOSDB) publication No.
