You've definitely achieved the goal of light and simple, I'd say.
However, there might be an opportunity here or there to lighten even further:
1. For that weight, you could go with the GG Murmer Hyperlight, at 8 oz (7 oz savings).
2. Depending on use, you could bring a razor blade instead of a knife.
3. A few other >1 oz savings, such as substituting a lighter bottle, wallet, losing the watch, etc.
