I have used Rutlands Fireplace Mortar to very good results. The key being that you cure the mortar to the blade before heat treat. You want it to stick to the blade during the crucial quench to develop the hamon. It needs to stay put on the blade, keeping that part you want to quench slowly as hot as possible for as long as possible. I would put it on thick, and generously. Leave the part of the blade that you want to harden, completely uncovered. You want that to quench as quickly as possible, especially with 1095. It's finicky about that and requires a very fast quench. The better that you accomplish those two things, the better your hamon will look. I found the best place for me in my location to get the stuff is Amazon. Here is a link to it for reference. Good luck and post your results!
