Got tired of constantly sharpening the blades that comes with it. Also the factory blades are thicker and hard to pull through thick leather unless recently sharpened.
I started using regular box razor blades and they seem to work much better. They are thinner and glide through thick leather like butter plus you just replace it with a fresh blade when needed.
Been doing this for awhile and never had them slip out or anything.....Surely I'm not the only one doing this?
