Product Description

https://technocretetrading.com/shyg2pwja7 The 4 micron CBN emulsion used in conjunction with one of our new Kangaroo leather strops is quite possibly the single most impressive sharpening accessory we’ve ever used and every single person who’s tried it agrees. One kangaroo strop and one bottle of 4 micron CBN emulsion are “must have” items!

see 4 Micron = 4,000 grit
