gotta love the good ol' single action switchblades

other knives with metal springs were around before that spetsnaz beauty, all very lethal, the earlier versions available were coil spring if I remember correctly, and very dangerous to charge and keep on your person due to triggers without safetys.

spetsnaz would have been better off recycling the rabbit hole pistols that we used in vietnam for ranged kills, for close quarter throat cutting and cold cocking the knife is superior.

i have bought 6 of these....yes 6....and used one for a test expecting to break it.....well i took it and it went EASILY through an 8 inch phone book and was still locked up with no blade play so my guess is that if someone breaks into my house it will go about 4 inches into them
