Gentlemen,

Many things have been said about Belgian Blue Whestone (BBW). It's supposed to be coarser than a Coticule. It's supposed to be slower than a Coticule. Some use it as an "intermediate" stone. Some say it's "4000 grit", and treat it as a slow version of the Norton 4K. Some use it in between a 1K synthetic stone and a "proper finisher", often a Coticule. Many use it for honing kitchen knives, but never for razors.

Elaborate information about the use of this whetstone is nearly impossible to find. Even on our very own Coticule.be, BBWs remain somewhat mysterious and often overlooked hones. They are inexpensive. And that, doesn't predict much good, at least not in the mind of the market.

In January 2010 (a year ago), the research team of Coticule.be started an extensive experiment with the goal to determine the abrasive yield of Belgian Blue Whetstone. Are they capable to reclaim a dull edge with a bevel that requires some work? Are they capable of bringing that edge to sufficient sharpness for shaving? Are they capable to finish a razor's edge? And if so, how smooth is that finish?

Today, it is with humble pride that the research team of Coticule.be presents the end report of that experiment. We hope you'll find it worthwhile.

Then the light shone, trumpets sounded and I got to the other side, where men shave with smiles on their faces, razors pop hairs, and a continuous choir singing «~~Keen and Smooth~~» is heard everywhere. (Matt)

I love the BBW side of my LPB. Thanks to Bart and all the researchers who made this happen. Can't wait to dive into it.

I checked for this at work today and must have missed it.

I can't wait to try this at home on my 8X3. Thanks, Bart! :thumbup:

So finishing with edge-trailing strokes? I am going to have to try this.

When I finish honing on my oozuku asagi I tend to do stropping strokes on just water and then finish on a very light X stroke that is in the normal honing direction so the back honing makes sense.

Fellows! A wonderful read, thank you. Very well written and it looks like the number crunching has been well utilized.

I believe that an eight man test sample, given the size of the straight razor community might well be representative in a meaningful way. My assumptions about who these eight were lead me to believe that the personal skills employed may not be...:)
(Though the modified unicot procedure is an excellent choice given the wide success of the method.)

My thoughts turn to the variances between the two BBW hones. Did either of them exhibit these pink dots, for example, or do they exhibit any quartz inclusions? (Even though I realize we are off into the last 5% netherworld once we open that discussion...:rolleyes: )

regards,
Torolf

PS: Damn glad this site has the talent to back up its fundamental prejudice to noise.

None of the BBW samples have the pink dots, that some of them display.

I will take both stones with me tomorrow and place them on the flatbed scanner at work. That will provide us with details surface pictures.

No doubt this research will stir certain pots.:rolleyes: We may have to start a new forum section: The Blue Cave. :)

Kind regards,
Bart.

Bart, I took the liberty of mentioning this thread in a new thread on B&B (someone had to, right?). I hope you don't mind the publicity. :O
