Help on complex feature

Afternoon everyone,

I modeled up a pistol grip that has a particular sweep cut pattern "knurl" in it and I was able to get it exactly the way I want however it was very very cumbersome and I had to use numerous planes, surfaces and sketches making it very time consuming and most likely very fragile to changes and rebuilds.

I was hoping someone could shed some light on a more efficient way of pulling this off that's not so cumbersome. This was the only way I could figure it out so any help would be greatly appreciated.

Some things to note however are; The profile that does the sweep cut remains NORMAL to the surface it is cutting along its entire path, which was the main criteria I was trying to meet also the cuts are 20° left and right of vertical which should be easy to see.

Thank you,

Gary Acosta
