I would suggest finishing the blade before installing the handle.
As Quint said, the tip on the #3 Wharncliff is too thin.
I understand that in Canada, you can only make knives in the summer, so that gives you from the third week of June to the first week of August to get everything done before the snow comes
But, take some time and hand sand the bevels smooth and flat.
Remove all the coarse grit scratches.
Work on the fit and finish of the handles ( #4 goes right across the plunge line).
You can go to the shop and start to grind out a knife by just shaping the steel and seeing what happens, or you can sit down and do some planning and drawings. almost everyone who makes knives can tell which way a knife was made.
Look at some photos of knives made by makers that you like. See how the elements go together.....how the shape flows from handle to blade. Notice how crisp the grinds and lines are.
Make some sketches.
Plan the procedures you will take.
Take your time.
Don't go to the next step until you have finished the last one.
In the beginning, work on one knife at a time. There is little learning experience in making the same mistake four times.
If you rush to make four knives at one time, you get four knives with the same problems and quality issues.
By doing one at a time, you can progress in your skills and eliminate some problems. If you make four knives slowly , one at a time, the last one should be much better than the first.
