So I was just wondering is mar-tempering worth the extra hassle and expense. what tangible benefits are gained.
Let us consider alloy heypereutectoid steel specifically cpm M4, especially for this next question

let us say we want our knife at 63 Rc is it better to austenize at higher temp say 2200 F and temper at a higher temp or austenize lower and temper lower. Which will yield better toughness
is it true that at higher temperatures more carbon is dissolved into the steel, presumably disolving carbides, and freeing carbon to form martensite?
if so which; high austenize, and high temper or low austenize and low temper lends higher carbide volume, or better wear resistance
