400 or 600 grit 'wet or dry' black silicon carbide paper (US grit and description - I use 3M products for my abrasive sheets).
Garnet paper is usually too coarse. Silicon Carbide paper is very uniform, and usually finer grit than standard garnet paper. 400 grit is agressive for detail work, 600 is pretty much polishing paper. If you use the different grades of silicon carbide wet-or-dry paper, cut into strips and glued flat onto a piece of glass plate with spray adhesive you can hone cutting and turning tools, and chisels and planes and scrapers, far sharper than you can with honing stones. This is how I sharpen all my instrument making tools - I learned it from this link http://www.shavings.net/SCARY.HTM You can use this method with great success to true up the edges of straing-edged cabinet scrapers, and if the edge is really true, once burnished it can take an amazingly fine shaving - great for minimal truing of the wheel. Also, with all the instrument builders here, I thought this link would be helpful for those not already familiar with it.
