Both the Gamma and the Eagnas pathfinder tools are useless. They are too thick to be of any use. I own both as well, because they came with machines I've owned.
I do however own the Kimony pathfinder. It's much thinner and much more useful than the other two. Except I don't use it either.
I just bought it to complete my set of Kimony Awls.
The bottom two pictured. The silicone sleeve is just to keep the two pieces together.
