Hey Guys and Girls! Just wanted to take a second to introduce my latest offering, the EDC-4. Taking Ankerson's advice a few months ago, I decided to look into Elmax. Needless to say the performance was excellent so I pick up a few sheets. Thanks Ankerson, trying Elmax was a great decision. These knives are heat treated to 59-60Rc by Peter's heat treating, of Meadville, PA. The specs are as follows: OAL is 9", blade length of 4.25", blade thickness of 5/32", blade height of 1.25". The blades are skeletonized under the handles to improve balance. A new addition to my knife designs are my new custom 416 stainless fasteners. The same fastener will fit all of my models moving forward. They feature an oversized slot for easier handle removal, requiring no specialized tools. Also stop by my new website www.SurviveKnives.com take a look around, tell me what you think. Oh, forgot the best part. They are on sale now at the SURVIVE! website for only $165! Domestic ground shipping included.
