For the minimalist but demanding straight razor honers out there, here some larger coticules in rectangular format and selected quality, with slurry stone included.

NEW! Now available in two formats:

Small: 100x40mm (about 4"x1.6")
Large: 150x40mm (about 6"x1.6")

"Handmade in Belgium" and "Selected Quality" Stamped (some older stock remains unstamped, it is the same quality though)

This formats are ideal for honing kamisori (7/8"x 1 1/2" blade depicted, obviously not included), as its width is enough to hone most Japanese razors with minimal or no X pattern (quicker honing). For longer western razors they make ideal travel hones and minimalist bench stones for X strokes.

Unbeatable price/quality ratio; looking for a no-nonsense razor hone, you found it!

The slurry stone included is Coticule.

To finish a razor with only this one stone and slurry, follow the dulicot method:

(depicted stones are just examples; but unlike the bouts, the sizes are standard and quality uniform, so there is nearly no variation apart from one stone to the other)
--------

The grit of all coticules varies between 6000-8000 grit and can be stretched by braking down the slurry and playing with the pressure. They are finishing stones, still very hard and give a famously keen edge to razors, yet they are not as hard and release slurry quicker than the japanese stones i'm listing, and hence are more easy to use.

Unlike Jnats, coticules are very consistent stones; in general they are a bit slower cutting than the former, as the geometry of the particles (garnets) is obtuse, but therefore leave a smoother and less serrated edge.

Please note that the creamy side (Coticule) does the honing, the blue one is just support and for holding. In the past this was a Belgian blue stone of grit 4000, which could also be used, but nowadays they use Portuguese slate as support, which does not have any particularly beneficial sharpening properties.

Before use sprinkle in water (Coticule whetstones don't need to be soaked beforehand). They produce slurry rather quickly, but a slurry stone will make it grind quicker and increase the versatility.
