Just got pinless blades for my Ferm scroll saw. Eek...so small....scary small. Where to keep safe? Which is which? Which to use? And last but not least what on earth was I using. So I made this. A bog standard biro holds 12 spiral blades with ease. The washer tells me what is currently in the saw and the block has enough space for what I need to know. Hope this helps other newbies like me.
