It's been established that I have some OCD when it comes to cleanliness and organizational matters. I have a relatively small/narrow shop (9'x25') and when everything has its place, it stays uncluttered and improves my work flow and efficiency.
This space (for me) started as a musical rehearsal area with a few tools for house projects. I had one blade in the miter saw and one combination blade in the table saw - easy. Time has passed .. I've grown wiser ... at least older ... the shop took over and I've accumulated a larger variety of blades. 80 and 90 tooth fine cutting blades for drum shells, acrylic blades for other drum shells and plexi, 40-60 tooth blades for other projects, cutoff wheels, circular saw blades, etc.
I needed/wanted a storage solution other than a few nails on the wall with the blades knocking against each other in some random fashion. I wanted them all in one case, organized, separated, and mobile. I had an idea .. I also had plywood, poplar, and hardboard ... weird right?
