Shaping stainless steel pin stems

Hello everyone,

What is the best way to file/shape/sharpen stainless steel wire for
pin stems? There are several suggestions in the archives for nickel
silver, but since I’ve never worked with stainless I’m not sure
which would be appropriate. The blue zirconia disks from Ikohe sound
right, but I can’t find a source that will ship to Canada. Thanks in
advance – any suggestions would be much appreciated.
