I chipped one of the jaws on my Regal debarbing a Gamakatsu T10 salmon/steelhead hook. I probably had the hook in crooked......Tying with the regal has made it easier to get the barb pinched before tying. I've had good luck with the barbless jig hooks such as the fulling mills. I got so many with barbs though, sometimes on days I try a lot I got a bad habit of forgetting, or not getting a good pinch on the barb. Some of the micro barbs I just seem to miss I think, until the first tiny fish doesn't come off.
