Finished lapping Spyderco Fine Benchstone ... not too shabby

My Spyderco Fine Benchstone had a bit of an arch in it going lengthwise, I decided to lap the side that had the ends touching the table first.

Stones Used:

(1) DMT Diasharp Extra Extra Coarse - 120 Micron (Flush often with Simple Green)

(2) DMT Diasharp Extra Coarse - 60 Micron (Flush often with Simple Green)

(3) DMT Diasharp Coarse - 45 Micron (Flush often with Simple Green)

(4) Norton 1000 Grit Waterstone - 14 Micron (Flush often with Water)

Process:

With help from others on this Forum I did not press hard when using the diamond stones, light pressure with a lot of flushing with Simple Green. When I was done with the DMT's I wanted to see what the Norton would do ... would the Spyderco cut the Norton or would the Norton cut the Spyderco. I was surprised to see that the brown Norton waterstone developed a white slurry, to me that that was the white Spyderco being cut. It took just over an hour to finish this project.

Impression:

Touching the lapped side there is a slight difference in feel, however, there is a big difference when sharpening a knife. I'm very pleased with the end result and was happy to "break in" my DMT Diasharp stones, no more straggling high diamonds. I do not know how smooth the lapped side is to a new out-of-the- box Spyderco Ultra Fine Benchstone, but for now, I'm happy with my "double-duty" Spyderco Fine Benchstone.

Thank You to all those who helped me learn how to do this project, all the best.

Thomas, I'm glad it turned out well for you. That amount of time seems about right. No glazing? I'm sure it is as fine as those lapped from the contractor and labeled as Ultra Fine. After some use perhaps a dozen knives it will change some. Then hold that for a long time. You'll enjoy using the new stone surface you've created. DM

To me there is no glazing.

I've been using the Spyderco Fine Benchstone to finish the knives I sharpen and to touch up knives in the kitchen, this has given me a sense of how knives come off this stone. I'm impressed how the new lapped side adds something to the finished edges I thought were good, they now have more "bite".

I edge-trail 5-7 swipes per side with only the weight of the knife, then lay the angle down a degree or two more and edge-trail both sides another three swipes with knife weight only ... there is a difference.

Thanks Again for the help and link you shared about others lapping their Spyderco Benchstones.
 
You just did a not so easy stone modification. I congratulate you. Happy sharpening. DM
