I have 6 or 7 pry bars but needed a different one for a job. Know how many pry bars Home Depot has on display? 35! And there are larger more specialized ones in the roofing and concrete department. They have a new tool named the Air Shim that is called an “inflatable pry bar” and I can think of lots of times it would have come in handy:
IANALocksmith or burglar or EMT, but that ad seems a little deceptive. At about 14 seconds in, the person uses the tool to open a steel door that has a spring latch and a deadbolt. But it looks like there is no hole, or box, for the deadbolt to go into in the door jamb. That is, it looks like a dummy deadbolt put on to imply the tool, a version of the old “open with a piece of celluloid or credit card trick,” can open deadbolts as well. I may be wrong.
I agree with Kropotkin. Most modern spring latches have a pin that prevents the credit card trick. That tool looks like they have just developed a better version of the credit card. I can’t tell (from the video) how it would bypass a deadbolt or a **properly installed **spring latch.
