Here are a couple more of mine.

A standard "snap blade" tool with lots of extra blades in the middle. Imitation bone celluloid handle.
This is kind of a generic set and not the highest quality. The extra blades all fit. They were spares from broken sets I picked up here and there. Most blades fit most of these kinds of tools. So many were available to me at one point I could afford to just pass over the rusty ones. If you can imagine.
Nobody wanted them for -any price- 30 years ago.
To the left (closed) is a much better set.
And at the top is a screwdriver set that is the only one I've seen. In the original box with 80% label no less. No way I could leave this behind when I saw it. heehehehe

Open

Here is the better set open. Tooled art noveau decorated outside and green braise leather inside. It has much nicer tools and a much sturdier handle. The handle slips were broken when I met it (why I could afford it) so I made new rosewood slips for it.
The Murmac set is revealed! It has a wooden universal driver handle and a magnetic drive plug to hold the various bits. The drive plug is made to fit any brace as well.
So you can use the bits in any brace, and any brace bit also works in the wooden driver handle.
