Will, I found myself, just the other day walking along with my raceknife marking away, ever so contently, I got to #5 and applied 5 straight lines instead of the "V", I gouged it away and applied a proper V. I used to use chisel marks but have gone to the race knife, the East side is simple slashes while the West side is the same except a slash through the whole number, #1 West looks like an X or #ten. I have not constructed a ten bent frame, yet so it has not been a problem.
