Back in the 1950's the Latama company built a few stiletto
proto-types with unique plunge style releases and square buttons.
Currently, they are considered to be the rarest and most valuable
of all antique Italian switchblades as only about a dozen or so are
known to exist. They have passed between collectors hands in
amounts of up to $10,000 per piece. Little has been known about
how many were actually produced and in what sizes they were
built in. Recently, accurate information in regards to these knives
has become available and released in a newly published book
named "Switchblades of Italy."  
I have been privelaged to actually hold original vintage 9" and 13"
Latama square button stilettos in my hands. From pictures and
holding these actual knives I have recreated this style of knife in a
13". They've been kept close to the antique vintage styling as
possible with a few modern improvements of our own. Offered in a
limited run of 5 hollow ground Kris blades and 5 hollow ground
Bayonet blades in 13" AOL. Ten square button knives total (plus 2
proto-types) are serialized and signed by myself "BURN."     
The following two square button knives are 13" AOL. #2
Kris and #2 Bayonet. Hollow ground blades, solid nickel
silver bolsters-buttons-and safeties. Scales are highly
polished solid black horn with flush finished nickel silver
pins. Swivel bolster release. Locktabs, buttons and safeties
are all square. All hardware has been mirror polished. Serial
numbers and signature are inside the liners. 3/16" blade
