they are not neccesarily ground by ernest, some are but some are not and there is no way to tell, although they are pretty neat, would be my edc if i didnt have a specwar CQC8 and i have 8 EKI's, imho $450 is tooo much, i have seen 2 for sale, both started in the $350 range, i paid $205 for mine (SN 117 IIRC), and the other one was withdrawn, i know ya will never get your $$ outta the thing for $450, although if ya just want a user w/a zero bevel grind, it would be ok, i would keep an eye on the forums for one, or ebay myself, $450 is a little steep; i think they sold for $350 or so when new to ECA members. emerson makes several 'semi' customs w/a hand ground blade and regular handle, the CQC10 comes to mind, and all the ECA knives, and none of them has increased in value in the secondary market, they have all depreciated, these are not customs, so ya aint gonna buy one and make $$ 5 yrs down the line imho.. now if it was a spec war custom, then ya got something which will appreciate down the line, but this is a 'semi' custom
the ECA persian is 2X neater then a std EKI P-Tac imho, satin finish, zero bevel, the blade is a LITTLE bit longer, action and lock seem better to me (i have both)
