Had to post this a website is selling ocean jasper for $300-554 .00 a pound! You could make some super priced hones using their outrageous prices for the little pieces of rough stone they were selling. I was thinking we should list the specific weight and hardness for each hone for comparables. If you get me pictures and descriptions I will look them up. It should be easy won't be exact since we aren't testing the specific piece but close. Even my knapping books list some of this. I am thinking could develop some data to eventually use a guide along with other details.
