Simpole - comfortable handle, comfortable carrying, solid reliable lock, durability, easy to sharpen (I mean straight edge - recurved is pain to sharpen). But of course most important edge holding.
My favorite knife for long time now Yuna Hard II. And I use it on 100% - I cut everything with it - drywall, stubs, grass, boxes, wood etc - whatever I need to cut. I also cut out splinters out of my fingers - I keep it hair whittling sharp and can do this without drawing blood... It is ideal knife to me now.
It is not excellent performer, but looking way better then Sebenza - more sophisticated I guess, but I like it.
Before my favorite was ZT-302:
Also good performer, excellent slicer because of fine grind. And nice looking as well.
And nice looking not because of decorative stripes but as whole piece!
And before ZT-302, I was carrying MOD Mark II for few years. Not as good in edge holding, but unbeatable in terms of usability to this point in time handle design.
Sabenza is just one knife among many others, to my opinion.
And I have very simple model as well:
Also excellent performers with Shirogami steel and hamon... And for some reason this simple knife which can left NASA crying behind in simplicity contest cost just $15-$20!
Thanks, Vassili.
