Will this effect performance of my edge significantly?

I finished the HT for a practice kiridashi (26c3 steel) and I seem to have gotten an auto hamon due to the thickness of my stock ( 1/4”). My HT was heat to 1475, hold for 10min after the temp equalizes, quench in parks 50, then temper 2x for 1hr at 350°. My evenheat seems to read a tiny bit higher than the actual temp so I compensate by 15°.

I did apply clay to the blade to prevent some oxidization, and then left a ~1/16” thick layer roughly 3/4” away from the top of the bevel. But I doubt this had much of an effect on the hamon, the stock I used was admittedly a bit over kill, but this is a test blade and I have more 1/4” stock than 1/8”.

Will this significantly effect the performance of my edge as I finish up the blade and put it to use? Or is these enough room between the edge and the hamon that for testing purposes this is fine?

Thanks,

That also looks like a single bevel grind, so unless parts of the backside are soft you will still have hard steel at the edge as you sharpen it. Polish up the back and have a look at it.
 
It is single beveled. The back side does show a similar pattern but it is slightly close to the edge.

I polished the edge up to 3,000 grit then stropped with white compound. After a few re stroppings I’m going to take it down to 1,000 grit + strop, repeat. Then the same with 800grit and see which I like best.

A a side note, I did notice on my 800grit stone that the hamon showed a lot of contrast but not much detail. Seems good for a working finish. I’ve never polished a hamon with stones before but I might try it out in the future. This was well after removing the oxides and scratches from etching

Looks fine, I had a clip point scandi in 26C3 Auto hamon on me without any clay 2 weeks ago, there's video of it floating around.
I was just dunking it (horizontally not vertical) into the quench tank too slowly, and it formed a quench line before the spine touched the oil.
This steel gets hard if you look at it for too long.
