Got my first coticule this weekend. lapped it with a Norton norton flattening stone then wet dry sand paper (800 then 1.5k) on a tile. Any advice on using this new stone? Also what is lapping film and how does it differ from sand paper?
Congratulations on the coti! Looks like a nice stone. Let us know what your honing experience is like there are lots of great guys here that can offer you wonderful feedback
As for Lapping film it is much higher quality and the abrasive is plastic backed rather than paper. It is the stuff they use to polish fiber optics with so it has to be really fine quality to do that. It works fantastic on razors as well and easy to do.
