... With top materials and very good functionality and robustness. Are manufactured in Italy by Dendra knife Lionsteel what ever is ansich a very good address. The Defender specifically different from its sisters / brothers Deer Hunter, Typhoon (and Tiger Jump) essentially by the low-profile design and low weight. The low-profile design is achieved through the built-in frame lock instead liner lock and the elimination of additional liner under the G10 grip on the opposite side. Nevertheless, the knife makes a very stable impression which is understandable on the basis of the still quite thick G10 grip and strong titanium shell on the other hand. Blade steel is like in the other D2 (a tool steel with heat treatment depending on the manufacturer-58- 61 HRC). The steel is the hardness according to very good cutting properties, rather difficult resharpenable and not entirely rustproof with the stonewash treatment - so you should oil every now and then some. The approximately 4mm strong blade has a flat ground and came very sharp out of box to. Opens the backlash mounted and depending on the tightness of bearings screw (smooth - unfortunately only one tool in the delivery, an additional 8-Torx makes sense if the screw "goes through empty") centered centered blade either with your finger or stylus Flipper. The flipping funktionniert best when supported with a gentle swing from the wrist. Also, opening with your finger pen / pin is fine and pleasantly soft. The pleasant to cross Frame Lock sits approximately centrally and at massive ejected blade very tight (have a bit hurried along with the file) - so that the additional Roto block mechanism seems somewhat superfluous to lock. The handle is very comfortable even for large hands and fits perfectly in your hand. The G10 material is milled in the now somewhat worn Anso (Jens Anso) -style, the titanium polished and pocket friendly to the Roto Block wheel. On top there's an on going from handle to blade coarser but not unpleasant Jimping. For finer work can be fingertip in the cavity on the blade top. The clip is designed quite tight, acu a lanyard eyelet is not missing. Conclusion: Except for the very tight frame lock (but is likely to be different from copy to copy) there was nothing to complain and an extremely robust, powerful but pocket-suitable diameter that mE his money is absolutely worth it. Who is not in frame locks should be times anschaun the other Dendra models that play high as in size in the same league.
