Custom Invader, Proto#1. from Andre De Villiers, and ADV Tactical. IMHO, this knife which was a grail to me, met every expectation I ever hoped a Custom could meet. The awesome looking on the clip alone, amazed me, in part because it was a special clip that I had asked for and designed with him. Not to mention the excessive and extreme file work he did on the spine. Here are the Specifications. To start with, it has some awesome S35-VN steel that's a chunk, nothing lightweight here. It's a combo satin blasted blade with, polished flats. Carbon Fiber inlay,, plus it has an extra, custom decorative, "filed" spine , and a beautiful Timascus Clip Also the Color theme is Annodized purple and blue. With (heavy duty rollers) in the pivot screw area. Also what I think is really cool is the fact that Andre allowed me to help him design the blade. We mashed two of his previous designs together, so it came out as a cross between one of his previous Tantos and one of his previous Wharncliffe's with my specifications thrown in. Andre has grown to be a great personal friend as well as one of my favorite knife makers. If you haven't tried one of his knives as of yet, then be sure and make a point to in the near future. #ADVTactical #friendsaregold #friendsstickethcloserthanabrother #knifecommunity #invader #grail #customknives #knifecollector
