Your comment about getting smacked in the face can be easily solved, just weld on a handle to the ends of them and cut the handles off later. You did not mention what kind or size of forge you have or have access to. When I did my dies of 4150 I heated the forge and put the die in and turned the forge off, let the die soak for a while then I fired up and let the forge heat and turned it off for a while I wanted to let the heat soak in to the interior of the piece and not just surface harden. after about three sessions I fired the forge and let it come up to a non magnetic red. I turned the forge off and let it darken a bit and repeated I did this three times also. I oil quenched and that takes a big bucket of oil. A welded on handle is worth gold then. I tempered in the oven for along time I think it was aboiut 8 hours before a file test let me know it was softened enough not to be brittle and chip. I don't have specs on the SS you used but you should research the data for that particular ss. the SS I use requires very specific heat treat temps and times. As was mentioned above if you can put your stuff in a larger load of steel to be heat treated you may save some money. REsearch anyone in your area that is useing the steels you used and see if they send thm out and if you can send yours with. I would start at the heat treat place and see who sends them the same SS as you have and go from there.
