One of my first knives by Ed Martin was a saber ground Rio model back in 2012.
It was the first knife I used in the field, both as a cutting tool and as a size reference, in the course of starting the flora fauna database I was just beginning at that time
Sadly it was also one of many knives sold to fund surviving the crazy winter of 2013 / 2014 in Michigan, and I had wanted another Rio with what Ed refers to as a sow belly handle ever since. And was hoping for one with a stainless blade and a higher grind. Then a couple of years ago Ed posted this Rio on his website, in a nearly identical profile, but in CPM 154 with a deep hollow grind and a tapered tang, and I grabbed it without much thought before it could get away.
Ed posted a video of the batch of these on his you tube to warn us that they were deeply hollowground and not meant as combat or survival knives, though being a knife it could obviously be used as a tool for survival if needs be, but they were intended to be hunting and field knives. Yet when I got it home, after years of being hung up on knives I had chosen for their durability and intended uses in "survival" baded on my childhood experiences and PTS-driven train of thought, I wandered if it were maybe too deeply hollowground for my uses and if it would be too fragile.
It definitely slices well
After 13 years of intense herblore studies and photography, I don't just photograph plants, I harvest quite a few I make quarts of herbal extracts with to boost my vitamin, nutrition, and polyphenol intake in the winter months, and the hollowground edge does a geat job of slicing the fruits and roots for the extracts as well as expected.
