"Kevin I 1000% agree with you that the Shabaria handle is just simply not right. However if that handle with it's hour glass curvature was extended lengthways by about an inch or so it would be a completely different knife."
I was thinking the same thing when I owned one. I thought, if this were a little larger, it would feel really good. I think it was based on larger daggers that they decided to scale down. The shape is actually good it just need to be scaled up about 10% to make it feel right.
I forgot about the D'allera, that is a great handle. In fact, I think it is better than the Manix. The fact is, there are a lot of really good handles and a handful of handles that make me scratch my head and wonder what they were thinking.
I still don't understand the Para, it is like they tried to do too much with it. Make that more simple like the Endura 3 or Stretch and I think it will fit more people in more grips than it does now. The only grip it feels right in is the one with your thumb on the back of the blade and your index finger in the choil. Who cuts like that? If I am a making a light controlled draw cut, I will use that grip but that is only about 10% of my cuts. There are a bunch of weird finger groove that don't fit your fingers. Why not just ditch the finger grooves and make keep it simple?
