The TOPS Knives Tahoma Field Knife is the result of a collaboration between Andy Tran of Inner Bark and TOPS. If you are not familiar with Inner Bark, you should be. It is a tremendous source of survival related information and gear reviews.
The Tahoma Field Knife (TFK) is a large survival knife that is ground from 3/16″ 1095 steel with canvas micarta slab grips. It features a 7 5/16″ main cutting edge with a short back up cutting edge on the spine near the tip. This back up edge is there to serve as a last ditch cutting method should you find yourself unable to sharpen the main edge.
The TFK has a notch on the spine that can be used to score materials to create a weak point for breaking to save the edge of your knife. This is an extremely clever feature since saw back knives rarely work well. It appears that Andy and TOPS were able to get the only useful function of the saw back, notching, out of a much smaller section of notches. This leaves the spine of the knife clear and square which is advantageous for other tasks like striking a ferro rod or batoning.
The TFK has a host of other features like dual bow drill pivots on the handle slabs, 2 lanyard points (1 near the wrist on the thumb ramp, 1 on the butt of the grip), a large finger choil, and a pry tip at the butt of the grip. It comes with a ballistic nylon sheath.
