Viper Oniro Ultem, Stonewashed MagnaCut by Denis Simonutti (V6012UT)

Oniro Ultem, Stonewashed, one of Viper's latest folding knives designed by renowned Italian knifemaker Denis Simonutti. The ergonomic Handle is made of composite, the blade is made of MagnaCut, a modern tool steel, which is now considered one of the best on the market. MagnaCut is characterized by excellent corrosion resistance and exceptional durability of the cutting edge. It is an exceptional example of a compact EDC (Every Day Carry) knife, an excellent choice for anyone looking for a reliable everyday tool.

Denis Simonutti, born in 1986 in Maniago, is an Italian designer and knifemaker from Friuli. He has been in the knifemaking business since 2010 and is known as the inventor of the Fingers Safe Opening System locking system. His passions are mountaineering and photography, which he combines with his design skills to create knives with unique design and functionality. He works with the Fox brand for which he designed the “The Claw” series of Karambit knives, combining oriental style with practical application.

CPMMagnaCut - a powder stainless steel produced by the Crucible® Particle Metallurgy(CPM) process hardened to 60.5-62.5 HRC. The high content of vanadium 4.0% (V), molybdenum 2.0% (Mo) and niobium 2.0% (Nb) guarantees accuracy and purity unmatched by more “conventional” steels. Designed and developed specifically for blade production by Larrin Thomas, it meets all the requirements of knife enthusiasts. With CPM MagnaCut succeeded in creating a steel that combines the unique properties of knife steels like no other. The result is a blade material that offers a remarkable balance of wear resistance, strength and corrosion resistance. There is no other steel on the world market today that offers a comparable combination of superior properties. This unique steel is produced at Crucible® Industries' U.S. steel mills.

Crossbar Lock - acrossbar that moves horizontally in longitudinal cutouts in the steel side plates of the handle frame. When the knife is opened, the locking bar overlaps the back of the Blade from above, preventing it from moving back. This beam is pressed down by two springs. Unlocking is done by pulling back the locking bar, the ends of which are accessible through cutouts in the grips on the sides of the Handle grips. In the closed position, the bar presses against the cam surface at the rear of the Blade, preventing it from opening on its own. Advantages of the Crossbar Lock include resistance to contamination, practical insensitivity to dynamic loads, ease of operation with both right and left hands, and lightweight operation.

Blade - wide, Drop Point type with a clearly marked belly, finished with a scratch-masking bath of fine Stonewashed pebbles. Ball bearings support the smooth operation of the opening mechanism of the wedge, which can be opened with a double-sided pin in the wedge (dual thumb studs). The small thickness of the wedge, combined with a high, flat grind (Flat Grind), gives excellent cutting edge geometry and extreme cutting performance. The entire blade is locked with an intuitive Crossbar Lock.

ULTEM™ - a plastic belonging to the Polyethermoids family or simply PEI. This material is characterized primarily by high mechanical and impact strength with a very high strength-to-weight ratio. It is also characterized by high thermal resistance (180⁰C) and high chemical resistance to all kinds of solvents (synthetic and natural), lubricants or other chemicals. Adding to this total insensitivity to weather conditions, we get an ideal material for knife handles.

Handle - grips made of transparent Ultem™, a virtually indestructible material insensitive to weather conditions, resistant to chemicals and mechanical damage, beautifully milled using CNC machine tools. The open-backed design, fixed with steel spacer sleeves, reduces weight and facilitates cleaning. The simple, secure design gives assurance of many years of use. Single-position clip (right), made of titanium, allows the knife to be carried in tip-up position.
