Spyderco Diamond rods

Define "use properly." They will not last decades with regular use. Maybe if you only sharpen your own knives and use them once a month or so. If you use them as often as I do (or even more often like a professional sharpener might), count on 10 years or so before you start noticing enough of a performance drop to want to buy a new set.

I'd recommend slightly soapy water (maybe a few drops of dish soap per 16 oz of water). The dish soap just breaks the surface tension so the water doesn't pool up on one point of the stone. You can use Windex, but that stuff smells horrible and you'll be breathing it in all day long. Mineral oil is completely unnecessary and will make a mess. Plus keeping your stone covered in Windex or mineral oil is more expensive than just using water with a drop of dish soap.
 
Use properly, meaning not putting a bunch of unnecessary pressure on them. If they lasted 2 years, fine by me, they were $30 stones. I know they'll last longer, just saying if it were the worst.
 
There are members here who're still using the same diamond hones after 20+ years (I'm one of them). So in the hands of most hobbyist sharpeners and knife collectors/users, yes, they can last decades under regular and proper use. Easy.

They won't last decades if abused. Pressure kills them, as does lack of regular maintenance (loading up, which contributes to over-pressure issues). Get a handle on that early on, and your diamond hones will be grateful for it. Chances are, your edges will be better for it as well.

Just to clarify M, on my screen it looks like a black dot on the DMT stone, that would be the extra C stone. The coarse stone has a blue dot. Is it just my screen?
 
it's just the vid. It's the blue dot side. :)

EDIT: one way to tell is the side the dot is on. If the dot is on the bottom of the plate, black is on the right, blue is on the left.
