and thats the key, use what works for you.
like above, we all seem to do things a little differently, and that will give us different outcomes with the same system.
I 'used' basic stones freehand for years, and I could get somethign that would pass as serviceable, but never sharp.
my first good edge was with a lansky - but I wasn't able to repeat that consistently. it wasn't until i came here and read about the sharpie trick and making sure I'm getting to the apex that it all started to click. i was then able to get a good sharp edge consistently with the lansky up to the 1000 grit that came with my kit.
once i was able to do that, i expanded, adding the 2000 'sapphire' stone, strops, diamond stones, and diamond pastes to expand my capabilities and further refine edges as I see fit. and continue to learn from the guys here
eventually, i want to build my own system that allows for better materials and more control - just havent done it yet
