German paratrooper knife

[Painter80]

I got this today with a pile of other stuff. Unfortunately
the spring inside is broken and the blade has been sharpened

Is there a spring? I thought this is a 'gravity knife". Are you referring to the spring on the locking lever?

[Painter80]

The lever pushes some type of spring inside so the blade can be extended when pointing upside down

Still a nice find.

Not broken, the trigger holds the knife open or closed, gravity does the movement. Looks like a Paul Weyersberg and in decent shape! Those were made in the late 1930's and are highly sought after and collectable. Just don't open/close it too much, the trigger spring will break. I paid @ $150 to get one with a broken spring and missing trigger fixed, easily worth double that but don't sell it on eBay.

There are numbers on the trigger and a mark on the spike to denote authenticity.

The lever on the one in the original post just flops up and down but won't let the blade drop. It is a weyersburg made knife. I'm still trying to decide if I want to get it fixed. I guess it really depends on how much it costs. I already had this one in my collection that is much nicer than the one I got today

That one is very pristine.

That one is very pristine.

Thanks. It's definitely one of my favorite pieces
