Here is mine today, after prepping some sticks for a fire
I don't like the standard handles on the 1, and i assume the Izula 2 would be more comfortable in prolonged use. Maybe those G10 ones would be better, but would affect the slim factor for pocket carry.
If i remember right, the handles for the 1 came after the knife, it was a vote or something at the time, and they don't cover the hole in the handle, thing that bothers me when using it.
May have to do with my grip, but my pinky rests lower because of that. So i rather have it paracord wrapped. That can be a pain if used a lot too..
The Candiru with scales is a lot more comfortable, but a bit less functional with its shorter blade and sabre grind. Plus, it is only a 3 finger grip.
Still, i love mine, and carry it from time to time. The first sheath that came with it, the nylon one, was good for hiding it though.
But the izula, as designed, slim, and thin, as said above, is very easy to conceal, and will prefer it to the small fish carry, especially in forest kind situations.
I prefer neck carry with the Izula.
