Howsit Guys and Gals,

So last night I start re-polishing my razor tang after I did a horrible job at it the first time, and I noticed that some of my normal sanding paper has different grits on it. Now I do realize the higher the grit the finer the paper, but is there a difference in lets say 220 and P220. Also, Maxi was kind enough to set me up with some Micro-Mesh, considering we don't have it in Africa, but because I hadn't touched it in quite a while, I guess humidity caused it to come loose from the fabric backing. So I Google-ed Micro Mesh and saw on Stewmac that there are different typed of Micro-Mesh, namely regular, AX, and MX. Do these differences have different standards in grid, meaning is a 1200 grit AX comparable to a 4000 grit regular?

Thanks for any insight on this.

Kind Regards
