Thanks,

I used to use this method with wood working tools in the past but upgrades to a whetstone grinder but I don't fancy using a straight on that.

At the moment I'm just trying to establish what I need if I'm going to hone my own on a tight budget.

At present I've ordered a Dragon's Tongue Welsh slate, its so cheap it would be rude not to, I shall almost certainly get a Chinese 12k as well for the same reason.

But below that I'm not sure. I'm leaning towards a King combination 1000/6000 but it seems a big jump between the 2 so I think I would also need a 2-3K grit stone as well which is when my searching turned up 2500 grit wet and dry paper
