I don't get it. The dude says "each set comes with a lubricant oil", and right after that says "pro tip: don't use any kind of lubricant with diamond stones". WTF?

Extra coarse diamond stone (70 grit)
Coarse diamond stone (120 grit)
Medium diamond stone (280 grit)
Fine diamond stone (600 grit)
Looks like 4 diamond stones to me.
dmedvinskyMy bad, I have a non diamond version. System is great for knives, keeping a nice angle. Sucks about the price on here.
I don't normally use it for sharpening but if I got a damaged knife that I need to regrind I use this, (apt life no space for a bench grinder).
