I gave up on hand sharpening as I could never get the correct angle. I now use the Lansky system and I am more than happy.
It just takes practice, one of the reasons why I reccomend a dedicated sharpening knife as you can walk away with it being dull with no issue. I find putting on a proper bevel to replace the crappy ones the factor puts on makes a world of difference, easy way of doing that is using the DMT Aligner clamp with a benchstone. After that put sharpie on the bevel and try to sharpen by hand, and check on the sharpie/edge frequently.
Just know your going to screw up a lot till you get it down, than you just don't screw up as much as time goes on.
I cheated earlier today and wanted to have a vague idea of what my new $6 Norton Economy stone could do (I believe it's an india stone as my best guess as it's definately not a silicon carbide). Well anyway I used my Aligner clamp with a Victorinox paring knife on it to reprofile it and sharpen it. Than finished up by wrapping a piece of newspaper around it and stropped it. Was able to easily slice through newspaper and shave arm hair. Not bad considering it's one of the first times I used the clamp that way (I've only had the 4in hones that came with my Aligner), and first time I used this stone.
I have found there is a trick to duplicating those types of results from guided setups like I did above to 100% free hand. Don't think, or at least over think. I sit back and listen to music and let my hands do the work and check on the progress. If I over think and focus on sharpening I will keep screwing up and I am being too harsh on myself which makes me change my technique, angle, etc more often than required. The real trick to being able to do that is practicing enough till you can do this though. I am definitely not perfect but my skill has been improving steadily for the most part minus a few "clicks" which increase my skill dramatically.
But if the lansky works for you, that's good you found something that works you can't argue with the results and your satisfaction :thumbup:. (hmm I just realized I rambled on quite a bit when I didn't need to, I need to get some sleep.)
