I'm sorry to hear about your injury.
I nearly severed my right index finger on Labor Day a few years ago. I couldn't look at that knife without getting shaky. I got rid of the knife because my confidence in using it was gone.
I dropped a Muela Buffalo Hunter(large recurve Bowie type knife) on my right foot. I had to reach down and pull it out. Incredible pain for days afterward and eventually it healed but with numbness radiating down to my big toe. It was a nice knife, but, I had to get rid of it.
Over the course of 42 years, I've had many cuts and stabs with many knives. Those are the only two incidents that shook me enough to sell those two knives.
You have two choices here:
1. You can swallow your fear of the knife, jump back in the saddle and conquer that fear.
Or
2. If you've lost all confidence in that knife and your use of it, get rid of it and chalk it up as empirical knowledge gained and get busy finding a replacement for your camp knife.
Loss of confidence in this instance does not entail the actual physical capabilities/attributes of that particular knife, just one's perception of confidence in the use of that particular knife.
Decide what the best course of action for you will be, jump on it and don't look back.
Good luck!
