Why do we include the built-in safety mechanism? For improved user safety and protection, our automatic knives at Tekto Gear feature a built-in safety mechanism. This built-in safety mechanism prevents the knife from piercing through any object impeding the blade's full ejection when the trigger is pulled. More importantly, the built-in safety mechanism can prevent the user from sustaining serious injuries in case the blade ejects unexpectedly.\nWhat happens when the built-in safety mechanism kicks in?
