The Canvas or Linen Strop is generally used before final stropping on the leather strop. It's purpose is to provide a very honing to the razor's edge, replacing most of the keenness which was lost in it's last use. While it has proven effective for this purpose, it will not sharpen a dull.razor but will extend the period between honings.
This strop is composed of high quality linen or silk woven into a fine or coarse texture.
A fine-textured linen strop is most desirable for putting a lasting edge on a razor. To obtain the best results, a new canvas strop should be thoroughly broken in. A daily hand finish will keep its surface smooth and ready for stropping..For a hand finish, the canvas strop is given the following treatment:
Attach the swivel end of the strop to a fixed point, such as a nail.
Lay the strop flat on a smooth and level surface and hold the unsecured end firmly.
Rub a bar of dry soap over the strop, working it well into the grain of the canvas.
Rub a smooth glass bottle over strop several times, each time forcing the soap into the grain and also removing excess soap.
Many modern Linen strops.often come from the manufacturer pre-treated with a very fine chalk-based abrasive. These strops are generally quite stiff when new and do.not require any break-in.though their performance does improve with use. Over time the chalk abrasive may be worn away. It can be replaced with Linen Strop Paste, which is itself chalk-based and usually is either white or gray in color.
