Hey guys,
I recently was given a reynolds ouzo pro 1" full carbon fork, but stupidly cut the steerer down using a pipe cutter I used a saw blade for the very last bit as I couldn't get the pipe cutter to go all the way through and I tightened the cutter very slowly. How likely is it that the fork has sustained internal damage at the steerer? Should I not risk riding it? are there any tell tale signs that the steerer is toast? there aren't any visible cracks on the outside but when i stick my finger down the 1" steerer I can feel small vertical lines running down 1-1.5cm - I think caused by the saw blade flaying the inside somewhat.

Help would be greatly appreciated.
P.S - this is for a steel road bike build using a vintage 4130 crmo frame.
