Diamond Triangles Questions

I am planning on getting a set of Spyderco Diamond Triangles. I already have the Sharpmaker 204. The Sharpmaker came with a video and instruction book that basically said to alternate 20 times each side of the blade on corners and flats of the stones. Do the triangles come with an instruction sheet? My question is do I do the same with the diamond triangles? I understand that it will vary with the type of steel but as a rule how many strokes on the diamonds will it take to reprofile a really dull knife and do you use the corners and flats on a plain edge blade?
 
I got some recently, and they came with no instructions. I haven't used them much yet, but so far I have found that about a dozen light strokes will bring up completely dull Henckel kitchen knives to a useably sharp edge...amazing! So far, I have only used the corners of them. Then, a few additional strokes on the white stones and these same knives are shaving sharp. I sure like mine.

The diamonds can remove a lot of steel. You also do not want to use very much pressure on the knife when sharpening. Too much pressure would wear out your diamond hones faster as you would knock off the particals from the metal sleeves. You can use a marker to line the edge of the blade so you can see where you are removing the steel.

Each steel is different so there is no set number of strokes. To do is to learn :D
 
I might be wrong but I think the diamond hones are primarily for reprofiling the edge with to the 30 degree back bevel. They will make knocking the shoulders off a lot easier.
 
Laredo,

Do searches on the username Mike990. He gives great Sharpmaker and Sharpmaker diamond sleeves advice.

How fast your diamond sleeves work depends on the steel's hardness, how much you're removing, how fast you're moving, and how hard you're pressing. Now don't press that hard at all. That's the quickest way to be out $56-90. The Sharpmaker is a case of slow and steady wins the race. Fast and furious rounds off the tips of your knives and grinds diamonds off of their sleeves. Been there, done that, and am relearning on sleeves with much less diamonds on them.

:(
 
As already mentioned, they do not come with instructions - much to my chagrin. I did not see the "do not press too hard" warnings until after I pretty much ruined mine.
It is a bummer because they are a very good addition to the 204.

Instructions on cleaning recommendations would be a good idea as well.
 
I got my diamond triangles today from Sawyer's Cutlery. I found him on eBay. I had money in my Paypal account so I wanted to buy from someone who accepted Paypal. I paid 59.99 plus 6.00 shipping. The triangles came with a red sheet that said use gentle strokes, pressing hard will dislodge the diamonds, diamonds are encapsulated and held to the steel by nickel plating, and the tip of the diamond does the cutting. I will use them tomorrow on my dull kitchen knives.
