hmmm not so nice!
I bought two of the newer DC4's as field sharpeners. Luckily I also have a small pocket hard arkansas stone, to go along.....but the black stuff is indeed no way near 2000.
I hope they don't wear so as soon as stated.....
The rough black stuff is a bit improved after 2 times use.
@ all the comments about whining!:
since alot of people dislike poor quality, its waste on the enviroment for manufacturing, its wast on your wallet (since avalability of cash
and heigth of prices in 2012 are terrible), the principles of bushcraft.....it IS something to whine about.
And: my knife is evenly important as my stones. A stone and its knife are like bride and groom!
My advice on quality and prices on stones; get a Honyama Quarry Stones while still available. They are the best so far as I know (in my modest opinion)
