Enjoy making them. Shop Talk is a good place to get plenty of advise on your knives as you learn.
Take your time and don't try and rush them to be done. Quality work takes time, and the skills to do quality work takes practice.
On the next knives, post some sketches , intended use, and other specs to get some input as to the design and function before you cut the steel.
The ones you have started are a bit blocky and look uncomfortable to use as they are.
A knife designed to use as a camping/cooking/utility blade will be smoother and have better ergonomics. These look purely offensive, and seem to have little use beyond cutting someone.....which hopefully they will never do.
The best real world uses for these three I see is:
The larger knife could be re-shaped a bit to make it more of a hunter.
The middle knife could be called some sort of rescue tool, but isn't really going to be of much use beyond something small and sharp.
The small "Razel" looking knife might find use as a box cutter.
I'm not knocking these knives, just pointing out places for design improvement on the next knives, and possible adjustments to these. What you have done so far is nice work. I agree that the grind on the Razel is very good.
Final note about carrying those smaller knives. Canada has some strict laws on concealed knives....especially if it looks like a concealed weapon.
A rigger in Alberta with a knife in his pocket can say he cuts rope with it and it is a tool. A farmer in Quebec can say he uses it on the farm for all sorts of chores. A person in downtown Toronto with a 4.5" tactical looking knife in his pocket will not have much luck with either of these reasons.
