I think I listed that tip many pages ago, and it really does work.
I use an electric sharpener and a burr rotary sharpener and the waxy prisma lead builds up on the blade, then the blade starts to catch at the lead as they are now both waxy. I keep a graphite pencil by the sharpener and every third time or so I sharpen it for a few turns between the prismas. This works with the razor type angled blade sharpeners as well.- it helps to keep the blade from catching on the lead instead of shaving through it. Sharpening a cheap #2 regular old graphite pencil will knock the build up off the blade and help to lube it to prevent new build up for a little while.
