Com: bob miller : The solder technique is silly.

If you have a key to copy, you have no need to make the solder key.

Also, it wouldn't be as easy as this video implies to make such a key that actually works.

Lastly, solder is so soft that it would probably just break in the lock anyway.

But why in the world would you make a solder key if you have the real key to copy anyway?

The razor blade idea is equally dumb. Razor blades do not have a saw edge.

You can't saw with it as shown in this video.

And it couldn't cut through anything but the softest metal and locks aren't made with soft metal.

That part of this video is faked.

What a waste of time! You really have way too much time on your hands.
