A few days back I tested these heads and they were some of the sharpest out of the box heads I have ever tested. With some ultra fine triangle croc sticks and strops these are now much sharper than the 125 replaceable blade control reading, plus the blade polishing is a nice bonus (second pic vs 3rd pic). I have got to be satisfied with these now, especially considering the thickness and steel quality. Not the ideal head for every situation, but for ultra big game they are my choice.
