The average kitchen knife is sharpened at a 15-20 degree angle. So, hold your knife perpendicular to the steel. You’re at 90 degrees. Go halfway down, you’re at 45. Go halfway down again, you’re roughly at 22.5 degrees.
This is close enough in my opinion, but you can always angle down a tad more for those last few degrees if you want. You want to be a little bigger than the actual angle it is sharpened at though, since you’re focusing on the edge, not the whole bevel.
