I was just tuning up my S90V Military with a Lansky Diamond set and the X-Fine (really not that fine!!) and had a big nugget of diamond on the stone that ground huge notches in the edge ( i say huge, but they were big enough). I ended up using the 2 finest stones from the regular Lansky set and got most of them out. Has anybody had similar experience with Lansky diamonds? Do the big nuggets ever fall off and let you get a decent grind? I got the diamond set for S90V and ZDP, and hope they won't be a bust.
