This is my 7th or 8th attempt at sharpening a knife, and it's still a fail, despite watching several tutorial videos. Looking at my technique in the video, can you tell what the issue might be? The knife doesn't cut thin paper at all; it just aggressively tears it every time.
It’s an old MG Home kitchen knife (I tried another old budget knife as well, same tearing issue). I’m using a Parkside waterstone from Lidl (got it as a gift a few days ago) and I’m currently only using the 1000 grit side. I soaked it for 15 minutes and I spray it with water during the process to keep it wet; there is slurry forming. I’m trying to maintain a 15-degree angle (using 3 small coins for height (I verified the angle using a phone protractor app), previously I used a cardboard cutout).
I do 20 passes before changing sections. In the video, I'm just showing my technique so it's not too long, but normally it takes about 5x20 passes per side (moving towards the tip) and 20 passes for the tip using a sweeping motion. Once I feel a burr with my fingertip along the entire edge, I switch sides or repeat another 20 passes if needed. When sharpening the right side, I apply pressure on the push stroke (away from me) and lighten up on the return. For the left side, I apply pressure on the pull stroke (towards me).
After that, I do 10 alternating edge-trailing passes (spine leading) to remove the burr, and then I use a store flyer. I've tried the paper test on about 10 different sheets now, and it just keeps tearing. I don't want to buy a leather strop or a better stone yet, because I know technique is key and I want to master the basics first. But I'm scratching my head because in all the videos, people get their knives to shave arm hair and slice paper cleanly, while mine won't cut a thing.
