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 Hunting and Kitchen Blades to Robust Friction Folders.

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!

This is a very powerful, Full Sized Friction Folder ~ Hand Crafted with Custom Contoured Black G-10 scales and Hand Forged 52100 steel.  This example by Mariano has a very Smooth Blade Action, the blade has no play in any direction.

 With a Full Sized Handle that fills the palm very comfortably, this is the ONLY Friction Folder that I have ever held that feels as Solid as a Fixed Blade in the hand!  The Stainless Frame is Hand Turned on the inside and the Tough Black G-10 Handle Scales have a wonderful Wood Like Grain.  

The 52100 Blade was Hand Ground by Mariano, it has a Dark Acid Washed Patina and a near Perfect Full Height Flat Grind.

The Polished Stainless Frame and Full Length Carbon Fiber Backspacer give this knife a Sturdy yet Lightweight feel.  When opened, the extended Tang used to open the Blade rests Flush with the HandleThe Blade is Perfectly Centered when Closed. 

The overall build is very strong without being too heavy and will especially appeal to those where a Locking Knife is frowned upon.

And a Padded Zipper Storage Case for secure storage.
