I personaly think Elmax has better edge retention than the S30V. I have two knives that are EDC in Elmax, one Ultratech, that has been getting used for just over a year now, and one Troodon that is my wifes EDC/work knife. Everyone’s daily use may be a little different, but for mine the Elmax has been able to keep an edge better. Though I do keep mine sharpened at 20dps. To be fair I only owned a knife with S30V steel for a month or so, just before getting the first Elmax blade, so have had much more time using the Elmax than the S30V.
