Hi,
I have the ByrdWrench and find it an interesting part of my M-T collection. While it is quite different from the conventional plier-based multi, it works well. We are likely to see lots of variations in the future ( Look at the CRKT Guppie and Zilla).
As to the comment about being "pricey", I'd offer that this is a complex tool to produce in a way that it works well. This costs money, regardless of whether it comes from China or not. That is the reason Spyderco dropped the original SpyderWrench. I have some 45 Byrd knives and find them outstanding value for the money. I feel the ByrdWrench offers the same.
Give this a good look. I think you may see something unique in this M-T.
Cheers - Joe
