ok so i got a sharpmaker for xmas and went to sharpen my leeks, ok so it says to sharpen at 18-22* per side so that would be 40 *. that worked ok but when i sharpied the sides and saw where it was taking material off it was semi flat on one side and the other just the edge so i checked the more acute side on the 30* setting and it seemed pretty close, infact its still not flat and just hitting the edge more, yet the other side is hitting the top of the bevel.

so my blade as one side that is probably 22-25* and the other is probably 13*

are the brown corse stones going to be the best bet for me to get it all down to 30 inclusive or do i really need to get the diamond sticks?

If you want it to go fast then get the diamond rods but for now the brown stones will work, it will just be slow. You will need to set a new bevel because the factory one is probabily not very stright. Go slow, keep it even and most of all enjoy it.

thanks, i ended up saying forget it for now and just did a 40 on it, my other leek was much better (right at 40) but that one is my nice leek that i dont use in the studio (its one of the models they made less than 500 of and i really like it so i dont want to mess it up).

i think ill just get the diamond ones later at some point to re-bevel it

thanks

SR Matt, I have yet to find a knife with both sides ground to the same degree. If they're out there, great, but I've never seen one yet.

Probably the best thing to do is get a selection of wet/dry from 220 through 400 (220, 280, 320, 400). Cut them into strips at least as wide as all three sides of the triangle stones. Cut the paper along the 8" edge, not the longer edge.

Now, you can carefully (creases and tightness-to-stone are important here) fold them around the stones and clip them with black binder clips, small spring hand clamps, or even tape.

This will grind your edges even much faster. Using the medium stones is futile in my opinion. I've used this method on at least 5 knives (probably more but I'm just sitting here guessing) and it works very well.

The reason I say cut the strips at least as wide as the stones is because: once you use the front face of the wet/dry, you still have two unused sides, BUT!, you can't use those sides unless there is a little more paper to go around the unused side of the stone to be clipped with.

Now, this will regrind the edge bevel (NOT "re-profile"- improper terminology [useless trivia here :) ]) your edge to either 15 degrees (30deg) or 20 degrees (40deg). You can increase the 15 degree to 12.5 if you want. You take a 1/4" small piece of wood and place it under the Shaprmaker base. Use a protractor on the bench and sighting by eye, move the wood inward or out to get your 12.5 degree angle. Sharpen ON THAT SIDE only until it's nice. Then, use the protractor again and get the other side of the base adjusted to provide a 12.5. Note that, since the holes are each placed on opposite sides of the base, the wooden wedge will not be in the approximate same place on the other end. Use the protractor.

Now that your knife is ground at 12.5 (this is an example, you could choose any angle, steeper or more shallow), now you can remove the wooden wedge, remove the wet/dry, and you have a knife edge bevel of 25 degrees. Using the 30 degree medium and fine rods to place a nice, clean micro-bevel on the edge. Works good. I've done it as I said at least five times.

The Spyderco diamond stones run about $60...maybe cheaper here or there. The wet/dry setup will cost you $5.

Good luck Matt.

I changed the post above to correct the incorrect terminolgy of "reprofile", a term which you did not use and probably already knew. I just mentioned it because so many use the term...wrongly.
