The greatest trick the devil ever played, was convincing the world he was not real...


Diavel - meaning ``Devil`` in the Bolognese dialect.

The Masterworks Diavel takes the standard model and elevates it to a higher, heirloom quality level, while still retaining its functional roots.

The Diavel is an extremely versatile little knife, unassuming to many, easy to carry and conceal, and very effective. The neutral handle allows multiple grips by the user and interchanging on the fly is easy. The asymmetric edge bevel means the blade geometry is robust, especially at the tip, while the Yasugi steel its made from allows a fine, razor sharp edge.

This Masterworks Diavel is made from one of the finest steels available, Hitachi’s Blue Paper variant of their Yasugi steel range. This steel is a high carbon powder metallurgy process steel which results in an extremely fine carbide structure once hardened. It also contains some of the highest carbon levels in a factory made steel making it very hard once heat treated, thus allowing the fine, razor sharp edges Japanese knives are known for. This is a relatively exotic steel still, and its availibility outside of Japan is still rare.

The Masterworks Diavel is finished with a traditional Silk Tsukamaki wrap on the handle, fitted to the customer’s specification in terms of colour choice.

The set is completed with a custom made Kydex Sheath with two mounting options as well as a second Pocket Hook Sheath for a more discreet carry.

The Silk Ito is sealed with clear resin to weather proof and cement it in place and provides a long lasting grip.
