First and foremost, a rescue tool must meet one central requirement: in an emergency and stressful situation, it must be quick, easy and reliable to use. The technically best solution to meet this requirement is a construction with an automatic thrust blade (OTF, short for Out-of-The-Front) with a robustly constructed and carefully crafted mechanism.
This poses a legal challenge for manufacturers in Germany, because according to the German Weapons Act, OTF knives are initially prohibited (WaffG §1 Paragraph 4 in conjunction with Annex 1 Section 1 Subsection 2.1.1). For the rescue tool Boker Plus Kalashnikov Rescue OTF, however, there is now a notice of assessment from the Federal Criminal Police Office, which negates the weapon and prohibition properties of this tool due to the shape of the blade. (File number SO13-5164.01-Z-543) Possession and even carrying of this tool in public (in Germany) is permitted spring out or slide back completely into the handle.
The absolutely reliable and proven mechanism with a powerful spring was adopted from the OTFs of the Kalashnikov switchblade series, which Boker has been selling abroad for many years, e.g. in France or the USA.
