All the ones I have owned in the past were crap..
But just for the nostalgia I would like the get a quality one that could hold up well as a daily carry knife if choose to use it in that role..

I too would like to know.  In for answers.

Walts / Latama did a run of flatguard picklocks about 10 years ago that easily rival the quality of 1940's-50's blades......but , like Osprey said, expect to pay.....they are 3-600 each on the secondary market now...

Most of the blades floating around in the 70's/80's/90's were junk.......and many folks associated the cheaply made "Rizzuto Estiletto Milanos" as the classic Italian switchblade.....they were made in Japan and Korea for the most part....funny thing is that they were so cheaply made, relatively few have survived in good condition....and now have a cult following, and bring good $$$

Look for a 5mm wide backspring, and solid (not hollow or stamped steel) nickel bolsters as a general sign of a quality knife. Picklocks are more desirable than bolster release.

a few of mine:

Thanks for the tips..I appreciate it

While not purely in the classic style, Protech makes some that are very similar:



Every Protech I've owned or handled has been very high quality, and very capable for EDC.
