Russ Kommer designed our P.T.S.™ (Pelvic Tool/Sharpener) because splitting the pelvic bone when dressing larger animals such as White Tail Deer and Alaskan Moose is difficult with a conventional blade, and may cause damage to the knife as well.
The P.T.S. is a high-carbon steel wedge with a chisel edge which will neatly split the cartilage at the pelvic bone seam aided by the tap of a nearby rock. There is no need to pack a hatchet.
In addition, we have coated the P.T.S. with a No. 400 diamond grit, creating a useful field sharpener. Use the flat side to touch up hunting knives. The back side has two grooves designed to sharpen fishhooks and arrow broadheads. The tapered, rounded edges are just right to sharpen serrated knife edges, including conventional serrations and our exclusive patented* Veff™ Serrations.
And in typical CRKT style, we have included a braided leather thong for grip and a handy carry pouch with the P.T.S.
At first I thought the 400 diamond grit was a little aggressive, but it smooths itself out after a few uses. I have since used it to sharpen all the knives in my house and my friends house. It renewed and corrected a lot of blades that had been severely neglected in a few strokes.
