The LockWrite combines two most frequently used police tools (a pen and a handcuff key) into a single design. The result is a functional pen that has been married to a durable heat treated ASP handcuff key. The core of the LockWrite is a precision, high density ink cartridge from Germany. Each LockWrite is packaged with a spare ink refill. The handcuff key of the LockWrite is produced from 4140 steel, the same alloy used in ASP Batons. A matte black body is accented in Gold, Silver or Black. A blue body pen with Silver accents is available for two pawl Security Restraints.
