Ive always sharpened up a few at a time.
Once they get a bit furred up or dulled, just swap over to another. Once theyve all been used, sharpen the lot again (i am a bit funny about liking them needle sharp, dont know why). In the workshop using a tungsten grinder, on site using a hand grinder with a worn flap disk (done at an angle so the grooves spiral around it, as its better than sideways imho). Cant be climbing down out of scaffolding, or out of pile racks just to walk over to a workshop to sharpen a tungsten. Hand grinder, 10secs then crack on.
All the worry about cutting off half an inch if you dip it (which i dont), or contaminated grinding wheels hasnt yet caused me any problems personally, and almost all the jobs the company i work for does have NDT carried out, mostly xray some 10% some 100%, and all jobs are 100% hydro/pressure tested.
In other words, wouldnt worry about it too much, just dont snap them.
