Getting ready to buy a rotary blade sharpener and need to know what the best one is. There was a thread on these about a year ago but new ones have since come out. I find mixed reviews on all of them when used on fabric. The guys that cut rubber need a good sharpener.
I wish there was a simple device. I use a hard 8" cardboard buffing wheel on my grinder. Works pretty well. Justs buffs the edge back to sharp. Until someone has a better idea Ill keep doing it this way.
No I don't use that sharpener. A lady into quilting has one and she used it on one of my blades. Since then I have gone to 107 bands and tubes or buying them from others. Saves me the hassle and get results I like.
You can use any buffer to polish up the edge on your roller knife blades till they slide through rubber like it was butter, as long as the edges are just dull and not nicked or bent. Just leave it in the knife and buff edge down at about the 4 or 5 o'clock position on the blade so that it spins a little as it buffs, then flip it around and repeat on the other side. any type of buff and compound that is softer than a sisal wheel will work, the stainless in the blades won't really discolor even a buff used with white diamond for final polish. Give it a try, it's easier to do than to explain.
