Its hard to recommend anything without knowing the application. Based off your description, I would say what you are looking for does not exist, and you will have to compromise somewhere or look to redesign.
Resins are not great at taking regular impacts from a metal edge, but then it also depends on how hard those impacts are. Resins made for laminating reinforcement like Kevlar are typically quite brittle, and wont last long taking regular impacts. Polyurethane rubbers are likely to be the most resilient, but they would need to be cast and do not have fantastic bonding properties, so no good for your Kevlar.
A flexible epoxy like Ex's EF80 might be the most suitable, but it still isnt going to take impacts superbly well - it is flexible rather than soft.
