The Blast is very similar to a Wave in terms of the available tools, just in a different configuration. The Rebar is basically a downsized SuperTool 300 (neither has scissors unfortunately).

Any of those four are durable, quality tools and would be suitable for a BOB, in my opinion, as long as they meet your feature requirements. I actually own all four.

I think if I were on a desert island, I might want the SuperTool 300 because it's the biggest, strongest multitool of the bunch. For everyday use the Wave is unique in terms of the one handed opening and the bit holder.

Consider the Victorinox Sprit X and the Gerber 400 Compact Sport also.
