Tin snips with blade lock

Blade lock

— the ability to lock the scissor blades in the closed position — it is in this position that the tool is most secure, it is also prescribed for storage and transportation (to avoid contact of the blades with foreign objects). Locking is usually done by means of a device that holds the handles of the scissors together — for example, a loop that connects the ends of the handles and is removed for the duration of work.
