Thanks for all the info guys, much appreciated!

I do have experience with honing, I have a 12K natural stone and have been using that for the last few months to just maintain my razor and have been getting good results. My interest in coticules was mainly just curiosity. I have heard a lot about them and just wanted to learn more. I'm thinking of buying just a very small one (cheap as possible) and just having a play around with it and use it just to maintain my razor and then use it to do more substantial work when I buy my 2nd razor. How much would it cost for a small coticule to get me started and where can I purchase one from? I'm in the UK.

Cheers.
