What does it mean when a lock pick has a "Metal" or "Stainless Steel" handle?
I am shopping for a good set of lock picks and I have run into some confusion. Some lock picks are advertised as having "metal" or "stainless steel" handles, while others do not have that advertised.

14 Piece Lock Pick Set-Metal Handles

Here is a good example of a set that has the "metal" handles. Perhaps from the description you can understand what it means and explain it to me a little better, because I am confused!

i.e - What do lock picks WITHOUT "metal" or "stainless steel" handles typically have for handles? Specifically concerning to other picks on the website that I linked to..

Best answer:
Stainless steel is a type of metal that is more resistant to corrosion than normal steel. If you are using these in a salt air environment or any environment that has dissimilar metals in an electrolytic solution, you will get corrosion, but stainless steel will corrode less, and slower.
