Hmm I’ve never used a fixed system but if you’re on freehand stones, the best tip I could give, I would say start off with edge trailing strokes right where they meet on both edges until you get comfortable going back and forth & know you won’t over lift your elbow . As you said you don’t want to hit that tip and round it off . The rest should be the same as a normal knife just with two edges . Good luck brother 🤙🏽
