There are a lot of things written about the use of hand planes about the pressure used when starting a the tool vs finishing a cut. Getting these pressure tactics down is essential to accurate planing, but once those are mastered try this.
Next time you start your cut, skew the body of the plane a bit. What this does is cause the plane to start the cut with one pinpoint of the blade as opposed to it’s full width. The beginning of your cuts will feel and look smoother and you can of course straighten out the tool as you go along the board. This also means you won’t have to take a running start when using planes with wide blades (jointers and 4.5 smoothers).
Now, go make a pile of shavings.
