hello, what's going on is after forging out the blade i will normalize by bringing the blade to a good orange color then setting it aside on the coal bed then again to orange and putting it in lime ( witch i plan on getting rid of ) then i try to drill a hole for pins and it's just to hard. the wraper on the material says it's an oil harding steel and it's warpless,maybee a brand name? also it has the recipe of the steel on the wraper but i am not to familar with the peticular's, maybee if i had some kind of chart?
