You are right!
The reason for the handle being too slim at the rear is that I goofed big time when doing this knife. When shaping the handle i found out too late that it wasnt exactly in-line with the blade and I had to remove a wee bit of material to have it half aligned. I also have too many scratches in the handle from using the coarse file too long, which couldnt be removed without taking away too much wood.
Thats why I stopped finishing with 6oo grid, leaving the handle quite rough and used only cheap leather for the sheat. I didnt want to start all over and the blade was cheap enough anyway ( 19,-), so I decided to keep it ( to not forget what I did all wrong)and have a not too worthy knife at hand when, for example, someone wants to borrow one.
Since I did incorporate a bigger swell in the horizontal plane of the handle and further forward, I still can grip it very good.
I used it yesterday for its intended purpose, batoning big branches which have been previously cut to pieces with a saw. And it worked!
My personal favoiurite is this one. A real Leuku, the other one is more of an american camp knife.
185mm carbon blade by Jarvenpaa, brass and fibre and birch, in a traditional pouch-type sheat with an unobstrusive seam and a medieval belt loop. there is a fat swelling in the forwarp third of the handle (horizontal plane again, thats what I prefer) and the rear end bulges, too :
