Old School STI Sabertooth Serrations

[aalbert]

I really like the look of the old Sabertooth serrations, and I was wondering if anybody here had the magic formula for doing them (looks like a fly or shell cutter, dropped into it at X angle, X depth, with X spacing).  

 

I am in the planning stages of doing a build on a Limited Optics type build, using a NOS STI frame from 28 years ago with a custom serial, and kind of wanted to incorporate some touches from through the years. I was thinking these serrations or something a little more modernized like the Accuracy X s swoosh, or something in-between.  I actually also like the old Steelmaster front lightening slots, but not sure if they would be taking too metal out of an tri-topped RDS Atlas slide. 

 

Thanks
