The knife was placed there for size comparison purposes, not to imply it is sharpened with those stones. For the record the knife was a $19 dollar Ebay purchase sold as a ""WW2 Commando Knife." I recognized the handle of what was shown as belonging to a Cattaraugas 225 Q quartermaster knife, described as being in "fair" shape and bid $19 and won. The ad didn't mention some idiot had taken a belt sander to it and reshaped the blade in an apparent attempt to compensate for losing a quarter inch at the tip. Yes, I am using my Lansky on it. We are up to arm shaving sharp at this time and it has gone on to the Arkansas (I am not impressed with the white ceramic on the Lansky fine). [Elsewhere I had asked what is the proper bevel for one of those knives is, now you know why I asked. I bought 4 of them on Ebay from different sources, in varying condition, but only one arrived sharp.] I had a suspicion that the Moraine might be a honing stone. It's in pretty good shape. The Arkansas is also. I have had both stones for decades but don't use the Moraine much. In my experience large natural stones from the pre 1960 era are both getting hard to find and better at producing fine edges than some of the newer stuff we find in Lowes, Walmart or similar stores.
