I use this before almost every shave. It's a piece of whippeddog's leather scrap with his hanging hardware, backed by wood from a local crafts store and pasted with crox. It's about 4 inches wide and 18 inches long. It was very cheap to put together, basically just pocket change. I think the key to using something like this is not to wait until your razor needs it, to use it as maintenance only. It's the single biggest thing I've done to improve the quality of my blade edges. By the way, it looks like the crox is caked on in the pic, but it's only the thinnest of layers.
