Mr. Ev's, or may I call you hevy? I am surprised that the obvious question here has not been addressed yet, except for when Steelshaper wisely touched upon it. What sort of tools and equipkment do you possess for in house heat treating? And also what kind of knives do you intend to make?
If all you possess is a forge or a torch you steels will have to be simple enough to accomodate those rudimentary tools- 10XX series, or
possibly 5160. If you have heat sources capable of holding precise temperature for extended periods of time, or even capable of progamable ramping features then the sky is the limit in the steels you wish to use.
If you have not equipped your shop yet or are considering upgrading the equipment then the first question that needs to be asked, but bladesmiths rarely do

, is what kind of knives do you want to make. If they will be mostly small slicers like skinners and hunters then steels like 1095, O1, W2 etc.. will top the list. If you want to make big bruisers and choppers or a super duper-stab-your-car-door-and-stand-on-the-handle type survival knife, then look at steels like L6, 5160, S7 or anything with carbon at .8% or less (.5% or less for the stupid super duper-stab-your-car-door-and-stand-on-the-handle type stuff
