I have owned:
- 2 izula’s
- izula 2
- esee 3, with TKC handles
- esee 4, with TKC handles
- esee 6
I used every one, but I only kept the 3.
The Izula’s is a fine knife, but on all 3 Izulas, something in the sheath dulled the edge on the middle of the belly. And it was a bit thick for it’s size (for me).
The 4 was a bit too thick and narrow, so it got a wedge shaped profile. Not as good a cutter as I liked. It’s the same spine thickness on the 6, but the 6 is wider, so the primary grind has a lower angle than on the 4.
I kept the 3 for the thin, slicy blade, and switched the 6 for a Skrama 200. To be honest I don’t use the 3 all that much since I use the clip to carry it, and in the winter, with jackets and wool sweathers, I prefer some of my dangler sheath knifes. Also, on sub 0 degrees celcius, I found that I had sharpened the 3 to a too narrow edge for it’s hardness, ao it rolled a bit on frozen spruce and birch. Not the knives fault, but again, know what you will be using it for. The 4, with it’s thicker grind, did not roll on the under the same circumstanses.
As long as you know what you are going to use it for, and getting a model that matches that use (thickness, width, edge angle = geometry and mode of carry), you probably will not be disappointed.
