I accepted a Victorinox Multitool to engrave a gentleman's name and a few "curly-ques" for a good pastor friend and have been regretting it ever since. Little did I know how HARD the metal is! Not only is it hard, it has soft/hard spots throughout the piece. It will cut beautifully for about 4-5mm and then break the tip, either hitting a hard spot or finding a hidden rivet. Either way, the tip will actually shatter, leaving a good sized chip in the face. I'm using a HSS graver with a 50 degree face, parallel heel and a dubbed tip. I figured a Carbalt or Cobalt graver would be too hard for the steel. Any way, if you're asked to engrave one of these......DON'T!!!!
