I didn't want to repost about this but right now I'm trying to sharpen my chaparral (on a sharpmaker) for the second time and I've got a couple questions. As I said originally the edge angle is too high/too blunt on the left side. I've sharpened it on medium stones by tilting the last inch into the stone and I'm just not consistent enough to get it very sharp toward the tip. This time around I want to use the diamond stones to reset the bevel correctly, which is where I seek some advice...
Should I pass it on the diamond stones at 40 degrees for a while? Is there any reason to use them at 30 degrees first, perhaps only on the left side where I need to remove metal?
Also last time I used the diamond stones I think I caused a very small chip, is that the result of too much pressure?
You want to use light pressure with the diamond stones. They are very aggressive and will take steel off your knife even with a gentle stroke. If you push down too hard you can wear down the rods quicker which isn't good.
If you aren't hitting the edge at 40 degrees in an area, then yeah I would start with 40 degrees doing passes until you make total edge contact on both sides of the knife. Then switch to the 30 degrees to slim it down a little more and make future sharpening jobs easier. You can then go up through the grits at 30 degrees to polish your back bevel then go back to 40 degrees and fine tune the edge.
