These are handcrafted products made of natural materials – no two strops are the same. May have slight aesthetic imperfections to the finish.

What is a strop and why are they useful?

A strop is used to maintain the sharpness of the edge of the knife. They are easy to use, and if you strop every time the knife has been used, the sharpness of the edge is maintained longer. This means that you do not need to sharpen the knife as often with other coarser sharpening tools such as a diamond or whetstone.

You use the strop by placing the edge of the knife against the leather and pulling the knife in the direction of the knife spine (i.e. you pull the blade away from the edge). Repeat the procedure about 20 times on each side.
One side has a rougher surface and the other a finer one. On the coarser side, if you want, you can apply stropping paste for increased sanding effect.
