@xellos99 could try using a jig or a plunge guide, I've had good results with both. However, I've just found that regular practice is key - been grinding a blade every night since before xmas, got piles of them all over the place! Until I got some waterjet cut folder blade blanks, I was just profiling the blade shape using wickes mild steel and then (much better) GFS 01 steel (i.e. making no handles) and working through 36 and 60 grits with no expectation I was going to produce something worth progressing. Funny but its like you progress one step forward and two steps back, as a result of getting more confident and trying something new, then messing up but learning from the experience. Very often, something will just click and you have a minor eureka moment but in the process you'll probably have ruined what you were working on. Pleased to say I'm able to produce consistent results in either direction and I'm sure you will too very soon.
Yes I made a jig but found that because of the design of the jig, when I switched the blade to the other side I would get different result. So I thought to hell with making a better more accurate jig, I will try to get good at flat grinds free hand if I can. I'm not bothered about other grinds, if I can do flat grinds I will be very happy since its my favourite overall. I have 6 more blanks so will try one a day every day and see if I can improve each time
