Coticule, Latneuses, Hybrid




Name: Coticule, Latneuses, Hybrid
Provenance: Vielsalm, BE
Geology: Medium-grade metamorphic stone

Use case: Honing

Grit size: 6k-8k
Hardness: 5/5
Cutting speed: 3.5/5
Feedback: 3.5/5



These stones were at one point directly connected to the Latneuses, usually being present in the backside of Latneuses stones. The “hybrid” nomenclature was given to them in the past and I don’t know the reason. This layer of stone is composed of mostly crystalline quartz instead of spessartine and feels like it withstood slightly higher grade metamorphosis.

This whetstone feels hard, glassy, does not have the same versatility and is hardly suitable for sharpening. However, it is still a decent honing stone.
