16 cm Triangalo switchblade

[Dorsey]

Can someone help me date this? I can't obtain a clear picture of the tang stamp, but it most closely matches "Triangalo." As can see, it's suffered some storage problems, and someone (probably me) tried to sharpen it many years ago. The bolsters are nickel silver, but the button and lock are magnetic. The spring slides in, and I remember when it (the spring) broke while playing with it shortly after I got it. Oddly, the broken part of the spring is still present.

This was given to me by a friend in the early 70s in much better condition. I don't have any special attachment to it, but it's close to the exact opposite of a 33 cm Italian picklock I recently acquired and I'd like to display them together. Would it be worthwhile having the spring and scale repaired by a pro? Or, is this just a low-end knife that isn't worth much?

Thanks for your help.

Definitely worth fixing, to me most Italian stiletto type knives are all the same , just hoopla over different tang stamps. Italians where knife marketing pros … your knife is collectable and likely made in the 50s

It's an earlier knife made (or marketed by) a desirable manufacturer.
It is worth having it professionally repaired.
