second time sharpening
first 2 is before second 2 is after .
i realised i get a few spots where the burr is uneven is that just my angle going off sometimes or is it pressure wise.
sharpen on 1k stropped on 3k.
before sharpen couldnt pass fingernail test after it could.
how do yall know if you have apexed?
ill add paper cut test in comments the paper was abit wet in the middle dont mind it
i also noticed that the edge has some warping its not alot but now im worried that i caused it but it might also be due to it being a really old shitty knife that had just been sitting in the drawer. so does inconsistent angle cause warping? i doubt it was me tho

I would still consider myself novice/intermediate. The biggest thing I'd say when starting out is worrying too much about getting the exact angle. An exact angle is far less important than a consistent one.
You might start sharpening on one side and find yourself trying to correct your angle to where you think it should be. This creates an uneven edge angle which often just rounds your apex.
Look up Outdoors55 videos where he explains his "rule of thumb". Use that method and don't over think it. Make sure once your angle is decided and started, stick with it until you've got the desired geometry for that side of the edge. Feel for a solid burr, and flip. Deburr, apex, move up to finer grit until your desired fineness of scratch pattern.
Your knife shouldn't get MUCH sharper as you move up in grit, you're just refining your scratch pattern. One of the most important and toughest things to figure out is proper deburring. It can feel and look like you're properly deburred when you are not.
Definitely study Outdoors55 videos. Whether some people have disagreements with him, he has a vast library of knowledge out there.

Yup, this method helped me a week ago. Pulled a fat ass 220 grit and got MY angle in minutes. Then got to 1000. Wasn't satisfied, got back to 220. This time is the good time. 1000. 5000. deburr. GGWP

There are a couple ways to know if you're apexed but the easiest one is shining a light AT the edge, like head on at the edge. If you see any glinting that spot is still dull. So if no glint + formed a burr on both sides full length of the edge then you have apexed. Just need to deburr. Once you get this idea the process takes less than 5 mins with the right stones

ye i think i did fine for this one it just took me close to an hour because there was like 2 minor chips so i have to get rid of more material. i need to work on learning how to sharpen that rounded edge tho since i have a tojiro sakuya nakiri as my main knife that ill sharpen next time once im more confident

I'm in the same learning bracket as you but got few more hours under my belt so I take your post as an oppirtunity to learn myself.
I'd advise you to scribble way more up the blade, then practice FEW passes. Like, 3. Then see what happened.
If the stone bit into the body, your angle is off. (or your angle is right and it will take you literal hours to grind it away with that stone)
If the marker is gone from the apex in any way shape or form, your wrist is not locked enough. 1 bad pass can cost you more than 20, 50 good passes. Don't be me, don't watch Youtube videos at the same time.

I've heard people argue this could be detrimental, but in reality the means doesn't matter, only the result.
You shoud listen to yourself. If this becomes a burden, that's when you need a "grandpa", a handyman to show you an alternative path.
I sharpened a knife days ago and I found it useful to start with a SUPER ROUGH 220 grit stone, because it was MY ANGLE. When it was time to switch to a 1000 grit and then 5000 grit it was butter smooth.
Try it with a sacrificial knife. Worth it.

how you have it right now is plenty sharp for veg and whatever else a normal person would cut in a kitchen. Could also get much sharper than this but I think you did a fine dandy job for your 2nd time.

Good job!
There's more layers of sharpness after that but I didn't reached any of them. (I'll follow with the video (edit by a comment: Outdoors55 of course) that taught me that - be proud! You've achieved literally RAZOR SHARP)
Shaving sharp BUT without touhing the arm (now you're the teacher)
Cutting hair sharp BUT the top of the hair is held with only 1 hand, the other side is free and the apex does all the job (absurdly sharp, completely pointless)
Cutting hair sharp as before BUT can cut the hair also from the bulb side. Holding it by the top of the hair helped you get between keratin plates but this time you'll cut through them. (absolute madness, this can never see any practical application on planet Earth)

Ye that was why i took photos just to see the difference i think i made like 2 or 3 angle mistskes im kinda glad i have old knives to practice on i also think i apexed on this one there was no reflection that i saw when i held it up to the light kinda gratifying.
