Hero Series - Air Force
 
The OSF3.5 has been one of those knives that has always had a huge following. OSF stands for "Open Source Folder."

As Jake says, "When I started this project in 2010, it was after I had spent countless hours researching folding knives, mechanisms and lock geometry. I thought to myself, why not put this information into a solid model so that everyone who is getting into making folders can start with a finished idea to look at while they build their very own awesome knife. So I set out to make the knife in such a way that it could be made with simple tools, no CNC necessary. All you would need to do is waterjet cut a blank and start drilling and tapping."

The knife design itself is a modified sheep’s foot blade with a properly engineered frame set. The single point rear standoff/backspacer is large enough to handle knife stresses but small enough to allow a rather large handle to blade ratio.

The blade steel is CPM-S35VN, with an excellent heat treat that seamlessly flows into and out of the titanium frame set. There are several options to choose from to make this knife your very own -- including pocket clips, pivots, backspacers, and inlays. This all adds up to a NPD (Never Put it Down), not just an EDC!
