GoBrah. I too have that sharpener and have used it many times with success. I think the trick is to put a drop of oil on the stone before you sharpen the blade. I have a cutter / blade that I use for fleece only. it seems this dulls a blade quickly. so I get out my blue sharpener. I have used this on material blades also, but not with a large sucess rate. if a blade gets too dull, those little blue sharpeners don't work.
