Viper Berus 1 Jade G10, Black PVD M390 by Tommaso Rumici Knife (VT4012DGJ)

Berus 1 Jade G10, design by Tommaso Rumici. Forged from a single piece of steel, this lightweight 95g compact multifunctional knife from Italian brand Viper. It features a comfortable handle and a razor-sharp, short strong blade with a rounded cutting edge.

M390 Microclean® - the highest quality modern tool steel. Manufactured using powder metallurgy technology with extremely high corrosion and abrasion resistance. High-chromium steel with a chromium (Cr) content of 20.0% and vanadium (V) content of 4.0%. Hardened in the range of 59-61 HRC. The steel has undergone vacuum and cryogenic treatments and double tempering. Manufactured at the Böhler-Uddeholm steelworks in Austria.

PVD (Physical Vapor Deposition) a vacuum deposition method used to deposit thin films by condensing an evaporated form of the desired material onto the surface of the workpiece. The coating method involves a purely physical process such as high-temperature vacuum evaporation followed by condensation. The applied coating has a very high hardness which significantly increases the resistance of the blade to rust and abrasive wear.

Blade - Drop Point type with clearly marked belly was finished with matte PVD coating. The small thickness of the blade combined with a high, flat grind gives us an extremely effective cutting tool. Spine jimping, a notched support on the back of the blade, and finger choil, an undercut for the index finger, provide precise control of the cutting direction.

Handle - is the result of ergonomics research, despite its size, provides a secure grip. Made of G-10 plastic (fiberglass compressed under pressure with synthetic resin), textured to improve grip confidence, riveted directly to the blank, provides a virtually indestructible design. The rounded shape of the covers eliminates sharp edges. On the back of the handle an enlarged lanyard hole, a hole for attaching a belaying line.

Sheath - when designing, great emphasis was placed on the ease of carrying and retrieving the knife. Flat, lightweight holster made of Kydex plastic. It comes with UltiClip, a practical multi-position clip suitable for attachment to a pocket or trouser belt. This allows the Berus to be used as a clinch pick (a short knife for ultimate defense in the clinch). Clinch Pick knife, a destructive tool in direct contact, ideal for self-defense also from a sitting position. In addition, the Berus sheath is compatible with the Tek-Lok mount as well as can be worn around the neck like a neck knife.
