CASE KNIVES
High quality, extremely collectible handmade knives since the 1800s.
SHOP CASE KNIVESCrafted in Maniago, Italy, the Viper Turn NO Folding Knife combines traditional aesthetics with modern engineering for a folding knife that feels at home in the field or in refined hands. Designed by Fabrizio Silvestrelli, this knife features a 3.23-inch satin-finished blade made from Bohler M390 Microclean stainless steel—renowned for its excellent edge retention, high hardness, and resistance to corrosion. With a Rockwell hardness of 59–61 HRC, the blade performs with dependable precision, whether slicing, piercing, or handling daily tasks. Built around a robust lockback mechanism, the Turn NO stands out with its advanced double-spring system, delivering smooth operation and solid, reliable lockup. The pivot system runs on thrust bearings, allowing for controlled, fluid deployment via the dual thumb studs without sacrificing the sturdy feel you'd expect from a lockback folder. The handle is a fine blend of classic and modern. Titanium liners and bolsters are machined from a single piece of GR5 titanium, then sandblasted for a clean, matte finish. They flow seamlessly into warm walnut wood scales that provide both ergonomic comfort and natural beauty. The contoured grip ensures a secure hold, while the precision build guarantees excellent balance in hand. The titanium bolster adds subtle contrast and visual appeal to the rich wood grain of the handle.
A shaped GR5 titanium pocket clip supports discreet, right-handed carry. The knife also comes with a leather pouch and is shipped in a branded cardboard box for protection and presentation. Attention to detail carries through to the rounded spring backspacer, crafted from tempered W.NR.1.4034 steel and accented with fine filework. Every element, down to the AISI 303 stainless screws and pivot hardware, reflects Viper’s commitment to superior fit and finish. Whether you're a collector, craftsman, or everyday carrier with an appreciation for top-tier steel and old-world charm, the Viper Turn NO offers unmatched sophistication in a practical, compact form.
