Not a review but rather to show you the edge stability on my AK made by Kumar. This took me 1 hour 20 min to split without stopping. Afterwards I took my ceramic stone and 1 swipe per side is all it took to get it back to shaving. The edge on the AK is very shallow being only between 10-15° per side in comparison to my CAK which was much steeper. I like lower edge angles.. its not necessary on even a chopper with 5160 and good heat treat. I have a VLUK on the way which I will do a review on.
