I'm still working out some small details but here is a bit of information!
Steel - .227" CPM D2 Stock
This is the Crucible Particle Metallurgy (CPM) version of D2 steel. The CPM process essentially refines and improves the steel. I'm starting with .227" thick stock, it will wind up just a bit thinner after sanding to perfection! The steel is made in the USA.
I chose CPM D2 as I feel it has a great combination of edge holding, toughness and rust resistance. It is nearly stainless, tough because it is a tool steel and holds an edge like crazy.
From Crucibles Site:
Conventionally produced high alloy steels are prone to alloy segregation during solidification. Regardless of the amount of subsequent mill processing, non-uniform clusters of carbides persist as remnants of the as-cast microstructure. This alloy segregation can detrimentally affect tool fabrication and performance.
CPM steels are HIP consolidated from tiny powder particles, each having uniform composition and a uniform distribution of fine carbides. Because there is no alloy segregation in the powder particles themselves, there is no alloy segregation in the resultant compact. The uniform distribution of fine carbides also prevents grain growth, so that the resultant microstructure is fine grained.
Advantages of CPM
For the End User:
Higher Alloy Grades Available
Improved Wear Resistance
Improved Toughness (less chipping)
Consistent Tool Performance
Good Grindability (on resharpening)
Framelock Construction with .190" Thick Titanium Frames
I chose 6al4V Titanium for the frames as I feel it is the very best material I can possibly use.
The lock will be carbidized with 72 Rockwell hardness Tungsten Carbide. I will do this to prevent wear and provide smooth lockup and release.
Hardware
The biggest in the industry!
I'm planning on a 1/4" hardened stainless steel stop pin as well as 1/4" standoff and the biggest pivot available! The pivot head is just under 1/2" with a 1/4" shaft made from hardened stainless steel as well.
I am proud to say that I built the knife around the biggest hardware components that I know of.
Phosphor Bronze will be used for the washers. I feel it is the best for washer material strength, long term durability and lack of friction.
Pocket Clip
Titanium Clip - Tip up Deep "low rider" Carry
I'm using a deep carry clip for the first few but may play around with the design on later folders.
