Best Practices for Sharpening Tools with Diamond Stones

I've been using something like WD-40 to keep my diamond plates wet. I just wipe off the muck and rewet the plate as I go. It helps prevent clogging and makes the sharpening process smoother!

For the angle issue, I've had similar problems with budget diamond stones. Sometimes, larger, higher-quality stones really help. You can use automotive glass cleaner as lapping fluid, which works great without needing the expensive stuff. It's also fine to sharpen dry, but I find using it wet gives better results!

A simple trick is to make a triangular wood block that holds your chisel at the desired angle before you even start sharpening. This keeps your wrists locked at the right angle. Also, a micro bevel is useful if your main bevel is set to the edge, but it might not be necessary if you're not using a powered grinder. And sure, you don’t necessarily need lapping fluid, but it does make for easier cleanup. I like to use Windex personally!

For large diamond stones, you can actually use them for flattening or freehand if the size allows. If you're sharpening with a jig, you might want to try aligning another stone next to it to extend the length for your guide. It should help utilize the full surface.

If you're a beginner, it might help to try freehand sharpening instead of relying solely on the honing guide. I had similar issues, and I found that watching Rob Cosman's sharpening videos was a game changer. They really clarified how to create the micro bevel. I usually do it on my 1000 grit followed by the 4000 grit, which works well for me. Also, I simply use paper towels to keep my stones clean—no fluids needed!
