At the chaos that was Blade Show 2019 I was intent to meet world renowned Knife Maker Claudio Sobral of CAS knives.  After talking with Claudio he introduced me to his good friend, also a Knife Maker ~ and that Maker was Mariano Yannoni.  I was thrilled to see that Mariano still had a few knives on his table, so after speaking with him and inspecting his knives ~ I purchased everything Mariano had left!  I am very proud to be able to offer his knives to my Customers.

~ Direct from the Maker ~

Mariano Yannoni is clearly a Maker who enjoys Hand Crafting Solid Working knives, from Custom Fixed Blades to Robust Friction Folders.  Mariano uses several kinds of Steel on his knives, but his favorite is the Hand Forged San Mai steel that he gets from his friend Claudio Sobral!

A Friction Folder is the oldest of folding knife designs, ancient Viking Age Friction Folders (or Penny Knives as they were later called ) have recently been discovered in Ancient Roman Dig sites where they were a standard item for men of wealth and privilege!

Marianno has used beautiful stag for the handles and Carbon Fiber for the bolsters to add to the overall beauty of the piece. 

This Mariano Yannoni Friction Folder is a very powerful, Full Sized Folder ~ Hand Crafted with Stag Handle Scales and CAS Knives Hand Forged San Mai Steel!  This example has a very Smooth Blade Action, the blade has no play in any direction and the Full Sized Handle fills the palm very comfortably. Blade is Perfectly Centered when Closed. 

The Hand Forged San Mai Blade has a 1095 Core with a 420 Exterior ~ it was Forged by Claudio Sobral and then Hand Ground by Mariano with a near Perfect Convex Grind. It has a Satin finish that clearly shows the gorgeous Lamination Lines of the Steels. Mariano decided to leave the Forge Scale near the Rear of the blade and on the Extended Tang for a Brute de Forge appearance.    

When opened, the extended Tang used to open the Blade rests inside the handle with the Custom Thumb Ridges of the Tang being perfectly matched with more on the Frame.  The Titanium Frame and Black G-10 Backspacer give this knife a Sturdy yet Lightweight feel.  

The overall build of this Mariano Yannoni Friction Folder is very strong without being too heavy and will especially appeal to those where a Locking Knife is frowned upon. 


A Thick Leather Pocket or Pack Sheath also made by Mariano is included.  

Tight stitching with a Soft Suede Interior and Belt Loop.  The Sheath holds the knife securely.

 This knife comes with a Hand Written COA 

And a Zipper Case for secure storage.
