All About Pocket Knives

Hi there everyone. New here. I could use a little expert help in Identifying a knife of mine. I bought it 30 years ago in a little shop in Venice, Italy. It's a pretty standard Italian picklock. 4 inch blade. The tang stamp says Rostfrei and also a letter B, but that's it. Just wondering what it is, and what the value might be, given it is 30 years old. I appreciate any info you can share. Thanks!

I`m no expert but IMO its a Beltrame . However it appears to be a bolster release not a "picklock" ? its worth whatever one will pay , about the same as a modern stiletto .

Worth a little more than a modern knife because it has liners that are cut for the front bolsters. This is a step that has been removed on modern knives. My GUESS is that it was made by Frank and Armando Beltrame before the two businesses separated. There are hundreds of Beltrames in Maniago, and a lot of them still make knives.

Nice one! Looks like the small button that is attached to the slide lock is missing.I had that happen to a couple of older knives.

Thanks for the replies. Good to finally have a better idea of what brand it is. Yes, the button on the sliding lock came off years ago. Thought of trying to fix that, but always concluded that I'd probably just make it worse.
