Featured Specimen

Coticule ID:


Coticule, glued to slate, mined at Ardennes's Old Preu quarry.
Most likely from the La Grosse Blanche Layer.
I has beautiful orange-brown color shades and some brown line running crosswise. A black manganese trace runs lengthwise.

This is a small rectangular specimen, but it's perfectly suited for razor honing.

Coticule Dimensions:

Speed on slurry:

Feedback on slurry:
A distinct feedback of fine abrasion. Water turns gray almost immediately. Abrasive feel slowly dissipates as the slurry is thinned down to a more watery consistency while honing during the Dilucot procedure. It does not seem to require as many dilution steps as some other La Grosse Blanche samples that I tested in the past.


Slurry Keenness Limit:
shaves arm hair well

Speed on water:

Feedback on water:
Glass-like feedback, with a slight hint of the same fine abrasion as felt on slurry. No visible discoloration of the water, but upon drying the edge with a paper tissue, black metal traces can be observed.

Edge Qualification:

This Coticule was selected by me (Bart), during a visit at Ardennes, while I went through a stock of smaller hones, selecting visually attracting pieces. These little rocks are practically jewels in the eye of the Coticule lover I am, and with their limited cost (40 EUR at present), it is even for a non-collectioner as myself, tempting to start a small collection of various attractive Coticules. But they're not just for display. With their small size, they lay on the hand very easily and after some initial getting used to, they work as easily and efficiently as the longer Coticules.
