4000 Grit should push cut through rolled up glossy magazine page?
Leather strop should make a horizontal slice through a tomato without anything holding it down?
I'm trying to sharpen an old knife and at 400 grit it doesn't do anything to paper and I have no idea to keep going or move up to 1000

I really liked this video on how to sharpen with a whetstone. I think I had an old stone laying around the house and sharpened all my knives pretty well with about 800 grit. The videos don't mention soaking the whetstones in water until the bubbles are gone. That parts pretty important.
I think 1000+ grit will get you push cut. 4000-8000 should be able to split hairs, or so I've seen on knife sharpening forums. The DMT kit makes looks knife sharpening super easy, but I had yet to try it.
If you have a bench grinder, buffing wheel, or CNC machine you could try this.
