The DPx HEST/F 2.0 is a German D2 tool steel folder mated to a U.S. made titanium alloy frame with a durable American G10 scale assembled by the crafstmen at LionSTEEL? in Northern Italy. The HEST/F was developed as the direct folding version of the HEST Original fixed blade knife and was dubbed the 2.0 because there were a number of significant modifications made to the original design of this brutal use folder. The goal was to increase strength without adding weight and to directly address concerns about ease of opening, strength of lockup and usability.Features:Blade is German D2 tool steel polished then milspec phosphate coatedTumble finish 6Al4V Grade 5 titanium alloy frame and spring frame lockPatented LionSTEEL RotoBlock? systemAmerican-made G10 handle scaleRemovable stainless steel clip and glass breaker (comes with replacement smooth head screw) with integrated lanyard attachment1/4" hex driverUnique wire strippers jimping and hard lashing pointsThumb grip/bottle openerKnife includes a unique, collectible Mr. DP skull adjustment tool which is used to adjust the pivot tension and remove/replace the glass breaker screw with an included flat screw.
