It’s a small thing really, but I never had a decent mini saw for cutting plastic and resin until now. Yeah, sure, I had saws big enough to take your arm off, but they are hardly appropriate for miniature work. So I liked the look of these micro saw blades when I saw Accurate Armour selling them. Perhaps the idea isn’t new, but I liked that they attached to a Swann-Morton scalpel handle, which is long time choice of blade for me. They work well!
