In reply to Mattlloyd10:
If you are desperate Needle sports do an ice screw sharpening service

But seriously, find a vice and a decent file and do your gear yourself. Ice screws can be done easily by hand with a small file set, ice axe picks are dead easy, i.e. just sharpen it back to original shape. Crampons are the same and even easier if you can remove the front points.
Don't use a grinder and sandwich any metal-ware between blocks of wood.
If you don't have access to a good vice, a few sheets of cardboard, a G-clamp, some wooden blocks and a kitchen table work just as well.
