EXTREM® by Merard S10 paste is a professional polishing compound developed in France by Merard specifically for processing materials that are the most challenging to achieve a mirror finish.


It is designed for ultra-fine polishing of knife cutting edges and mirror finishing of blade surfaces, allowing you to achieve an exceptional level of shine and smoothness without losing the blade's geometry.

EXTREM® by Merard pastes are compatible with cowhide, suede, kangaroo leather, nanofabric, Gunny Cloth, as well as cast iron and copper whetstones.


The S10 formula is specially designed for use with ultra-hard tool and powder steels, as well as high-carbon alloys, where conventional polishing pastes are no longer effective. The paste effectively removes microscopic marks left by finishing abrasives, creating a perfect mirror finish and uniform surface structure.


EXTREM® S10 is the choice of professionals who strive for a perfect finish on blades, where not only aesthetics but also extreme precision of processing are important.
